What is Internet Phone?

Internet Phone is a unique software product that opens a new and exciting dimension for Internet users. Up to now you could only use the Internet to transfer text and graphics. You could send e-mail to other users, or even have text "chats" with them, but didn't you ever wish you could actually speak with them?

With Internet Phone you can use the Internet to speak, with your own voice, with Internet users all over the globe! Yes, real-time real-voice conversations over the Internet!

All you need is Internet Phone, an Internet connection and a Windows-compatible audio device. Plug in a microphone and speaker, run Internet Phone and, by clicking a button, get in touch with Internet users all over the world at the price of a local phone call. Whether you want to meet new friends, get information personally, or make the direct business contact, Internet Phone is for you. A friendly graphic user interface and a smart Voice-Activation feature make conversation a snap. VocalTec's sophisticated voice compression and transfer technology makes sure your voice gets across in a flash and using only a fraction of the bandwidth.

Users that have two audio boards installed or that have an audio board that supports full duplex, can conduct conversations with two-way audio, as with a real telephone. This means that they can speak and listen to the other person at the same time. Others users have to take turns speaking during conversation.

Internet Phone uses the Internet Phone network as a global phonebook, always presenting you with an updated list of topics and on-line users. By connecting to an Internet Phone server you can access this list and call anyone on it. You can create new topics or list your name under existing ones, waiting for people with shared interests to join in. When you get to know a person, you can put his or her name under a Quick-Dial button. To call the person, simply click on her Quick-Dial button and a call to her is made, even if you are both listed under different topics. Once you establish contact with a person, communication is carried out directly over the Internet, and not through the Internet Phone network.

You and others can use private topics to block out unwanted callers, when you are waiting for important business or intimate calls. Private topics also let the members of world-wide organizations or groups easily locate each other without interference.

Of course, the quality of voice communication depends on the quality of your Internet connection. We recommend that you use Internet Phone on systems with an Internet connection of 14400 baud or more. Installing a voice compression card, such as VocalTec's VC Card, can also increase the efficiency and quality of communication considerably.


Starting Internet Phone

To start Internet Phone

1	Switch to the Program Manager window.

2	Open the group window that contains the Internet Phone icon.

3	Do one of the following:

   Double-click the Internet Phone icon.

   Use the arrow-keys to select the Internet Phone icon, and the ENTER key to start it.


Quitting Internet Phone

When you quit Internet Phone, the Quick-Dial buttons setup and the current Voice Activation level are automatically saved to disk. If you were connected to the Internet Phone network, Internet Phone disconnects you.

To quit Internet Phone

Do one of the following:

Choose Exit from the Phone menu.

Press ALT+F4.

  	Double-click the window's Control-menu box in the upper-left corner of the window.


Connecting to an Internet Phone Server

Internet Phone uses the Internet Phone server as a global phonebook, always presenting you with an updated list of topics and of on-line Internet Phone users. By connecting to an Internet Phone server, you gain access to the Internet Phone network, and you can access this list and call anyone on it. Note that once you establish contact with a person, communication is carried out directly over the Internet, and not through the Internet Phone network.

To connect to an Internet Phone server

1	Select Connect To Server from the Phone menu or from the Tool bar.

The Connect To Server dialog box appears.

2	The first time you try to connect to the Internet Phone network, the Internet Phone Servers dialog box automatically opens.This dialog box displays a list of countries and Internet Phone servers. It also includes a list of servers that are publicly accessible from any country. Choose your country, and from the list that opens, choose an Internet Phone server. Now choose "OK" and the selected server is added to the dialog box.

To access this dialog box again, choose the Servers button.

3	If you want to enter the Internet address of an Internet Phone server manually, type it in. Internet Phone also keeps a list of the last five servers to which you connected, letting you choose one of them.

You can connect to the Internet Phone network through any Internet Phone server. However, If you want to reduce response time and increase performance, it is recommended that you try to connect to an Internet Phone server in your vicinity.

If the Internet Phone server that you want to connect to does not use the default port, uncheck the Use default port option and type in the correct port number.

If you want to automatically connect to this Internet Phone server each time you run Internet Phone, check the Connect Automatically on Startup option.

4	Choose "OK".

Internet Phone tries to connect to the Internet Phone server. While the connecting process is in progress, the IPS indicator blinks in yellow. When the connection is successful, the indicator turns green.

If the Nick Name you entered in the User Info is already used by another person, you will have to change it. Choose User Info from the Options menu and enter a new Nick Name.

The first time you connect to the Internet Phone network, Internet Phone joins you to the general topic. The next times you connect to the network, Internet Phone automatically joins you to the topics under which you were listed when you last exited the Internet Phone network.


Disconnecting From the Internet Phone Network

When you disconnect from the Internet Phone server, Internet Phone saves to disk the names of the topics under which you were listed, and will automatically list you under these topics the next time you connect to the network.

To disconnect from an Internet Phone server

Select Disconnect From Server from the Phone menu.

Internet Phone disconnects from the Internet Phone server.


  Internet Phone Servers dialog box

This dialog box is used to locate an Internet Phone server. You must connect to the Internet Phone network (via one of the servers) if you want to use Internet Phone: this network is like an address book, and is used to locate other users or to browse for topics of conversation.

Remember that ANY of the server listed can be used to connect to the Internet Phone network. You can download the updated list of Internet Phone servers from our Web server (at http://www.vocaltec.com/). Download the file and replace the older file in your Internet Phone directory.

Dialog Box Options

Choose Public Internet Phone Servers from the State list to get a list of servers you can connect to from any country.

Choose your country or state from the State list to get a list of local servers.

Choose one of the servers in the list that appears and choose OK to add the selected server to the Connect dialog box.

If you connect to any one of the listed servers, you will be connected to the Internet Phone network. However, finding a server that is closer will result in better response time as the data does not have to be routed through several countries/sites to get there.


Joining and Creating Topics

Once you are connected to the Internet Phone network, you can start looking for persons to call, or wait for them to call you. The topic list makes this easy. By joining various topics, you can see the other users listed under these topics, and you can contact them. Your name is now listed under this topic, letting others that share your interests to easily locate and call you. It is possible to join up to ten topics at any one time. Of course, topics can have any name: you can create topics that only you and your friends will recognize. When there are no persons connected to a topic, it is removed from the topic list.

The resources of the Internet Phone network are not unlimited. You should not multiply topics unnecessarily. If you are no longer using a topics, and are the only user listed under it, leave it. This will help prevent network overload.

To join or create a topic

1	Select Call from the Phone menu, or choose the tool bar Call button.

The Call dialog box opens. The topics you are now listed under appear on the Joined Topics list on the right.

2	Choose the Join Topic button.

The Join Topic dialog box opens. This dialog box gives a global list of all the available Internet Phone topics. Of course, this list constantly changes as persons create new topics or leave existing ones.

3	Since updating the topic list can take some time, you must choose the Refresh button to get the updated list of topics.

•	If you already know the name of the topic you wish to join, you can simply type its name in the Topics box, without having to update the entire list.

•	To join one of the topics on the list, select it.

•	To create a new topic, type its name in the Topics box even without updating the list. Of course, if such a topic already exists, you will simply join it.

4	Choose the Join Topic button. The selected topic is added to the Joined Topics list on the other dialog box and the other users listed under it appear on the Users list.

To join another topic, repeat steps 3 and 4.

5	To exit the dialog box, choose Close.

The Join Topic dialog box closes.

6	You can now call one of the persons in the topics you have joined, or wait for others to join and call you.


Leaving a Topic

When you leave a topic, the other users connected to it cannot contact you, unless they share other topics with you, or have set your name under a Quick-Dial button.

To leave a topic

1	Select Call from the Phone menu, or choose the tool bar Call button.

The Call dialog box opens. The topics you are now listed under appear on the Joined Topics list on the right.

2	Select the topic you wish to leave from the Topics list.

3	Choose the Leave Topic button.

Your name is removed from the topic.


Using Private Topics

If you don't want to be accessible to all the other Internet Phone users, you and other users can use private topics to access each other. Private topics are identical to listed topics, but cannot be seen in the global topic list. Only users that know the exact private topic name are able to join it. Private topics can be used by members of world-wide organizations and groups to access each other without interference.

Of course, for a private topic to be of any use, it is preferable that you remove your name from any listed topics. It is especially important to leave the "General" topic, or many other Internet Phone users will be calling you constantly.

To create or join a private topic

1	Select Call from the Phone menu, or choose the tool bar Call button.

The Call dialog box opens. The topics you are now listed under appear on the Joined Topics list on the right.

2	Choose the Join Topic button.

The Join Topic dialog box opens. This dialog box gives a global list of all the available Internet Phone topics.

3	Type the private topic's name in the Topics box.

4	Choose the Join Private button.

If there is no such topic, it will be created. If a listed topic of that name exists, you will be informed.

The private topic is now added to your Joined Topics list.

5	To exit the dialog box, choose Close.

The Join Topic dialog box closes.

6	You can now call one of the persons listed under the private topic, or wait for others to join it and call you.


Leaving a Topic

Using Private Topics

Making a call to a person


Making a Call to a Person

You can use Internet Phone to call and talk with other users that are connected to the Internet Phone network and have Internet Phone running. You can call a person with the Call command, or by choosing a Quick-Dial button set for him or her.

If you want to conduct a full duplex converation with the other person, make sure the Full Duplex option is on before you make the call.
To call a person

1	Select Call from the Phone menu, or choose the tool bar Call button.

The Call dialog box opens. The Joined Topics list displays the topics under which your name is now listed. The Users list displays the other persons listed under the topic that is selected in the Joined Topics list. To see the names of all the users that are listed under all the joined topics, check the Show Users of all Joined Topics option.

2 Locate the desired person in one of the joined topics. If you cannot locate the person, you can try looking for him or her under other topics.
3	Select a person from the Users list.

4	Choose "OK".

•	A message appears on the message line, accompanied by a dialing sound, indicating that the call is in progress. One of the Quick-Dial buttons depicts a hand knocking on a door. This button will be used for interaction with the person. If one of the buttons already holds the person's name, it will be used. If all the buttons already hold other names, the wild-card button will be used.

•	On the other persons Internet Phone, a Quick-Dial button representing you starts ringing. He or she can answer your call by clicking on this button.

•	If your call is answered, you will be able to talk with the other person; if she is already engaged in another conversation, the message line will report "BUSY".

When contact with the other person's system is established, conversation starts.
TIP:

If you want a much faster way to call a person, set a Quick-Dial button for him or her. If one of the Quick-Dial buttons is empty, it is automatically set to hold the person's name. Whenever you want to call the person, simply point to the Quick-Dial button and click on the left mouse button. This has the advantage of being not only much faster, but also lets you contact the person even if you are both listed under different topics.


Receiving a Call from a Person

When another person calls you, the Quick-Dial button representing the caller changes its appearance to that of a ringing phone, accompanied by a ringing sound. The message line shows the caller's name. If none of the Quick-Dial buttons is set to represent this caller, the wild-card button is used to interact with the caller.

If  the Bring To Top On Call preferences option is on, the Internet Phone window will pop up whenever a person calls you.

Receiving a call

Do one of the following:

To accept the call, choose the caller's Quick-Dial button.

To reject the call, choose Disconnect from the menu or tool bar.

If you accept the call, conversation with the other person starts.
It is possible to make access to your system immediate, by turning on the automatic confirmation mode. If another person tries to call you while you are speaking with someone, the message line shows the caller's name, and the caller gets a "BUSY" message.


Conversation with a Person

Conversation starts when contact is established between two persons.
The message "CONNECTED!" appears on the message line.

Rules for conversation

During a conversation, you and the other person must take turns speaking. You cannot speak at the same time.

There are three modes: Speak, Idle, and Listen. The other person's Quick-Dial button changes its appearance according to the current mode, and the current mode is displayed on the message line.

When Speak mode is on, what you say is transmitted to the other person. When Listen mode is on, you hear what the other person is saying. When Idle mode is on, no one is currently speaking.

Internet Phone uses its Voice Activation interface to recognize when you are speaking, and automatically transmits what you say to the other person, if he is not speaking. (For information on fine-tuning the Voice Activation interface during conversation, see: Setting the Voice Activation level)

Whenever you can speak, the Internet Phone logo on the Status bar changes to the Speak Indicator.

The window's title shows the name of the person you are talking with. If the Internet Phone window is in minimized form, the minimized icon functions like a Quick-Dial button, and the other person's name is shown below it.

Talking with a person over the Internet

1	Speak.

When your audio device registers a sound, Internet Phone activates Speak mode, and what you say is heard on the other person's system.

2	When you are finished speaking (that is, when Internet Phone recognizes that you are silent) Idle mode is automatically activated.

3	When the other person is speaking, the button changes to Listen mode.

4	When the other person has finished speaking, the button changes back to Idle mode.

You can then respond by speaking again.

5 When the conversation is over, disconnect it with the Disconnect command.
Conversation can also be conducted manually, by clicking the person's Quick-Dial button to start speaking, then clicking it again to let the other person speak. In this way it is also possible to burst in and start speaking even when in Listen mode.


Receiving a Call from a Person

Making a Call to a Person


Switching to Full Duplex Mode

If you have two audio boards installed on your system, or if you have an audio board that supports full duplex audio, you will be able to conduct full duplex conversations. When in full duplex mode, Internet Phone records and plays audio simultaneously, letting you speak and hear the other person at the same time, as with a real telephone.

When you first run Interent Phone, it automatically runs the system configuration test. This test checks the connected audio devices, and if full duplex audio is possible, it will notify you that full duplex conversations will be available.

If you install an additional audio board, or switch to one that supports full duplex audio, run the test again to configure Internet Phone to full duplex.

If you are using two audio boards, make sure the audio input and output devices are connected to the correct boards (the input device should be connected to the board listed under Speak in the Preferences dialog box. The output device should be connected to the device listed under Listen.)

Once Internet Phone is configured to full duplex, you can switch to full duplex mode at will. Note however that a complete full duplex conversation will only be possible with another user whose system supports full duplex audio. When conversing with users that only have half duplex audio, you still have the advantage of being able to burst into their speech without having to use the keyboard or to select their button.

To switch to full duplex mode

Select Full Duplex from the Options menu or from the Tool bar.

Now you are in full duplex mode,  and you can conduct full duplex conversations with other people.
You can also switch to full duplex mode in the middle of a conversation.

To exit Full Duplex mode, deselect the Full Duplex options.


Full duplex conversation with a Person

Full duplex conversation starts when contact is established between two persons that have the Full Duplex option on.
The message "CONNECTED!" appears on the message line.

If the other users system also supports full duplex, the status bar will indicate Full Duplex.

If the other users system only supports half duplex, the status bar will indicate Local FDX (On the other users system, it will indicate Remote FDX). In this case a complete full duplex conversation will not be possible, but you still have the advantage of being able to burst into the other users speech without having to use the keyboard or to select his or her button.

Rules for conversation

A full duplex conversation is identical to a standard conversation, except for the following:

During a conversation, both you and the other person can speak simultaneously. Note that there can be a short delay before what you say is transferred and played on the other users system.

There are only two modes: Speak, and Idle. The other person's Quick-Dial button changes its appearance according to the current mode, and the current mode is displayed on the message line.

Button mode	Meaning
	SPEAK mode. When in this mode, what you say is transmitted over the Internet to the other person's system.
	IDLE mode. When in this mode, you are not speaking.
The other user can speak at any time. When he or she does speak, a small speaker symbol appears at the top left corner of the Quick-Dial button.

It is now possible to try switching between full and half duplex modes even in the middle of a conversation.

When the conversation is over, disconnect it with the Disconnect command.


Switching to Full Duplex mode

Making a Call to a Person


Disconnecting a call or a conversation
Disconnecting a Call or Conversation

The Disconnect command can be used to terminate calls and conversations.

To disconnect a call

Do one of the following:

Choose Disconnect command from the Phone menu.

Choose the Disconnect button in the tool bar.

Press F9 or ESCAPE.

Move the pointer over the button, press the right mouse button and choose Disconnect from the pull-down menu.

Choose another Quick Dial button to terminate the current call and start a new call.

Internet Phone will report "DISCONNECTED" on the message line.


Automatic Confirmation of Calls

The Auto Accept Calls mode determines how easy it is for callers to reach you: when it is on, access is immediate, and callers can immediately start talking with you. When it is off, you need to click the caller's Quick-Dial button to answer his call, or choose Disconnect to reject it.

To set the Auto Accept Calls option

Select Auto Accept Calls from the Phone menu, or the tool bar. A check-mark appears next to the menu item, and the tool bar button is highlighted.

If a person calls you now, there is no need for you to answer his or her call. Conversation with her automatically starts.

To disable the Auto Accept Calls option

Reselect the command from the Phone menu or its button in the tool bar. The check-mark will disappear, and the automatic confirmation mode is disabled.


Setting Quick-Dial Buttons

When Internet Phone is first started, the ten Quick-Dial buttons are empty. When you call a person with the Call command, one of the empty buttons is set to hold the person's name, if one does not hold it already. When all the buttons hold names, the bottom-right button -- the wild-card button -- is temporarily used to represent another person who is calling or being called. The Quick-Dial buttons are used for interaction with other persons, and change their appearance to indicate the current mode.

The Quick-Dial buttons also serve another purpose. They can serve as your computerized phone book, giving you direct access to other persons connected to the Internet Phone network. The Quick-Dial button setup is saved to disk, and remains the same each time you run Internet Phone. Once a button has been set, you can simply choose it to call the person. There is no need to locate the person's name on the topic list each time, or to be listed under the same topic.

To set a Quick-Dial button

1	Move the pointer over the desired Quick-Dial button. Click the right mouse button and keep it pressed. If the button is vacant, you can also click the left mouse button.

A pull-down menu appears next to the button.

2	Choose Set Button and release the mouse button.

The Set Button dialog box appears.

3	From the Users list, choose the person name that you want the button to hold.

4	Choose "OK".

The dialog box closes, and the button is set to hold the person's name. The new name appears on the lower part of the button.

Follow this procedure to customize the rest of the Quick-Dial buttons. Remember that your wild-card button setting will be overridden when a person that is not represented by one of the buttons calls you.

A person can appear on only one Quick-Dial button. If you set a button to represent a person who is already set on another button, the first button will be cleared.

Select Clear Button from the Quick-Dial button's pull-down menu to clear it.

Once a Quick-Dial button is set, you can use it by clicking on it with the left or right mouse button.


Using the Quick-Dial Buttons

Once a Quick-Dial button has been set to hold a persons name, it can be used for direct communication with the person. There is no need to locate the person on the topic list each time, or to be listed under the same topic. A pull-down menu for a Quick-Dial button lets you call the person it is set to hold, or to set it to another person.

To call the person set under the button

1 Set a Quick-Dial button to hold the person's name, if you have not already done so.
2	Do one of the following:

Choose the Quick-Dial button with the left mouse button.

Press ALT and the digit which appears on the top left side of the Quick-Dial button.

A call to the person is made.

To access the Quick-Dial pull-down menu

1	Move the pointer over the Quick-Dial button and press the right mouse button, without releasing it.

The Quick Dial pull-down menu appears. Commands which are currently disabled for the button appear in gray.

2	Select the desired command and release the mouse button.

Internet Phone performs the command.

Setting a custom title for a persons Quick-Dial button
Setting a Custom Title for a Person's Quick-Dial Button

You can substitute a custom title for the default name of each person which appears on the Quick-Dial button set for him.

Setting a custom title

1	Move the pointer over the desired Quick-Dial button. Click on the right mouse button and keep it pressed.

A pull-down menu appears next to the button.

2	Choose Set Button Title and release the mouse button.

The Button Title dialog box appears.

3	Type in the new title. It can be up to 8 characters in length.

4	Choose "OK".

The new title replaces the person's name on the Quick-Dial button.

To reset the person's Quick-Dial button to the default name, simply set the button again to the same person.


The Manual Activation mode

Sometimes, when the changing background sound makes conversation with the Voice Activation interface hard to use, you may want to use Manual Activation. Manual Activation can also be used like the MUTE option in many phones: it lets you talk without being heard on the other person's system.

To turn the Manual Activation on

Choose Manual Activation from the Options menu or the tool bar.

A check-mark appears next to the menu command, and the Manual Activation button is highlighted.

To turn Voice Activation back on

Choose Manual Activation again.

The Manual Activation button returns to its default look, and Voice Activation is now on.

Conversation in Manual Activation mode

Conversation in Manual Activation mode is identical to one with the Voice Activation interface, but is conducted manually. To activate Speak mode, choose the person's Quick-Dial button. To put Idle mode back on, choose the button again.

Note that it is not necessary for both systems to be in the same activation mode. One person can use Voice Activation, and the other Manual Activation.


Setting the Voice Activation Level

During conversation, Internet Phone uses a Voice Activation interface to automatically recognize when you start or stop speaking. The Voice Activation interface will operate differently with different input devices and with different levels of background noise. To make the Voice Activation interface run as smoothly as possible, you should set Voice Activation to the correct level.

To set the Voice Activation level

1	Choose Set Voice Activation Level from the Options menu or choose the button next to the colored bar at the bottom-right part of the window.

The Voice Activation level tool is now on, and the message "SET VOX" appears. It displays the level of audio recored by your microphone or other audio input device.

2	Speak to the microphone.

The bright colored bar should respond. This bar indicates the Voice Level. If it does not respond, make sure your microphone is plugged in and that there is no other open application that is using your audio board.

The level bar (the colored bar at the bottom of the screen) should rise in response to the level of sound recorded by your microphone. If it does not respond, then your micropohne is not properly connectedor another application is using the audio device. When the bar is at the far left, there is little or no sound. When it reaches the red part at the far right, it is very loud. The message line indicates how Internet Phone would respond during conversation:

IDLE  means that the current sound level would not be recognized as voice, and Idle mode would be activated. This happens when you stop speaking or when the voice level is lower than the Voice Activation level.

SPEAKING  means that Speak mode will be triggered at the current level of sound. This happens when the voice level is higher than the Voice Activation level

3	If they messages do not correspond to your speech, drag the knob to raise or lower the Voice Activation Level. Set the Voice Activation level to high values, if there is considerable background noise around your system, or if the connected audio input device is very sensitive. Set it to low values if you are not close to the audio input device, or if is not very sensitive.

4	Try speaking again and see if the response is now smooth. If it is not, repeat step 3.

5	Deselect Set Voice Activation Level from the Options menu.

During conversation, you can change the Voice Activation level in the way described above, without having to choose the menu command first.

Internet Phone saves the Voice Activation level setup on disk, so there is no need to repeat this process again unless you change your audio input device or unless it seems the Voice Activation interface is still not working smoothly.


Setting the Volume Level

If the volume level of your output audio device can be controlled by software, you can use the volume slider to set the volume level.

To set the volume level

Do one of the following:

Click on the thumb in the volume slider. Drag it to the left in order to decrease the volume level, or to the right to increase the level.  Clicking to the left or right of the thumb will move it in that direction, thereby decreasing or increasing the volume by a small amount.

Press the numeric keypad PLUS key to increase the volume, and on the MINUS key to lower the volume.


Working with Internet Phone in Minimized Form

It is possible to use Internet Phone while working on other applications, by reducing it to an icon with the Minimize button. Unlike other applications, Internet Phone is still active when it is minimized. Calls are still received and heard. When Internet Phone is minimized, its icon is not static: it changes its appearance exactly like a Quick-Dial button. In this way you can not only receive calls, but also initiate them and engage in conversation while actively working on another application.

The name of the person who is calling you, or with whom you are talking, appears below the icon. If the Minimized On Top option is on, the minimized icon is always in full view. If you also turn on the Bring To Top On Call option, The Internet Phone window will pop up whenever you get a call. You can see who is calling, minimize the window, and continue the conversation.

Suggestions for working with Internet Phone as a minimized icon

1 Make sure Voice Activation is on.
2 Set up a hot key combination.
3 Turn on the Minimized On Top and/or the Bring To Top On Call options in the Preferences dialog box.
4	Minimize the Internet Phone window by clicking on its Minimize button (the top right button on the Internet Phone window).

Internet Phone is now reduced to an icon.

5	Move the Internet Phone icon to a position that does not interfere with work on other applications.

6	Use the hot keys to initiate calls. When a conversation starts, the icon changes its appearance like a Quick-Dial button.

7	To expand Internet Phone back to normal size, double-click on it.


Setting the Internet Phone Preferences

The Preferences dialog box is used to set various options.

To set the Internet Phone Preferences

1	Choose Preferences from the Options menu

The Preferences dialog box opens.

Options that are on are marked by an X.

2	Select the options that you want to set.

Since Voice Activation enables you to talk without using the mouse or keyboard, Internet Phone allows you to make or disconnect calls with keyboard shortcuts even when the Internet Phone window is not in front, or not in focus. This is done by pressing a hot key combination with one of the keyboard shortcuts.

The hot key combinations don't interfere with the keyboard commands or shortcuts used by most other applications.

To set a Hot Key combination

1	Choose Hot Keys from the Options menu.

The Hot Keys dialog box opens.

2	Select the hot key combination that you want to use.

3	Choose "OK".

For a list of shortcuts you can use with the hot keys, see:

Testing your System Configuration

The system configuration test does two things. First, it checks the audio devices installed on your system to determine if your system can support full duplex conversations. Second, it checks your systems performance in order to make sure it is fast enough to run Internet Phone.

The system configuration test runs automatically the first time you run Internet Phone. If you install a and additional audio device on your system, or one that supports full duplex audio, you will have to run the test in order to configure Internet Phone to full duplex audio.

Before running the test, make sure there is no open application that uses your audio device.

To test your system configuration

Choose Test System Configuration from the Options menu.

The system configuration test starts.

•	If the test cannot find an audio device, it will issue an error. In such a case check again that no open application is using your audio device.

•	If the test detects more than one audio device on your system, it will automatically open the preferences dialog box, and will ask you to set one device for input (under Speak), and another device for output (under Listen).

•	If your systems performance is not fast enough to run Interent Phone, a message will report your systems performance mark as compared to the one required.


The Audio Indications

The audio indications are Internet Phone's ring, no answer, indication and busy tones.

You can customize the audio indications by assigning other sound files to them. You can use any sound file which is in the WAV format, and in one of the WAV audio formats supported by Internet Phone. It is also possible to turn the audio indications off, or use your system's internal speaker with or without the audio indications.

To set the audio indications

1	Choose Preferences from the Options menu.

The Preferences dialog box opens.

2	Choose the desired audio indications setup:

•	Use Wave Audio

•	Internal Speaker

For fun and recreation, use the Internet Phone topic list, where users can create and join different topics of conversation.

For private communication and for business, use Private Topics. These can be used only by the users that know their exact name.

The Quick Tour will explain how to do all of these.


 System Requirements

Before starting, let's make sure your system meets the system and audio requirements to run Internet Phone.

To be able to use Internet Phone, you need:

486SX PC - 25MHZ (recommended)

8MB RAM (recommended)

Windows 3.1

A Winsock 1.1 compatible TCP\IP Internet connection (minimum connection: a modem SLIP\PPP connection of 14,400 baud)

Audio requirements:

A Windows compatible audio board.

To be able to use full duplex mode, you will need either a second half duplex audio board, or a single audio board that supports full duplex audio.

An audio input device, such as a microphone

An audio output device, such as a speaker


 Setting Up the Audio

Now, let's fine-tune Internet Phone to your specific input device. During conversation, Internet Phone uses a Voice Activation interface to automatically recognize when you start and stop speaking.

To make sure your audio devices are set up correctly and to make the Voice Activation interface run as smoothly as possible, you should set Voice Activation to the correct level.

1 Choose Set Voice Activation Level from the Options menu.
The Voice Activation level is now on, and the message
"SET VOX" appears. The level bar displays graphically the level of audio recored by your microphone or other audio input device.

2	Speak to the microphone.

The bright colored bar should respond. This bar indicates the Voice Level. If it does not respond, make sure your microphone is plugged in and that there is no other open application that is using your audio board.

When the Voice Level is higher than the Voice Activation Level, Internet Phone will recognize this as voice, and it reports SPEAKING. When you stop speaking or if the Voice Level is lower than the Voice Activation Level, Internet Phone reports IDLE. The SPEAKING and IDLE messages should correspond accurately to your actual speech.

3	If they do not correspond to your speech, drag the knob to raise or lower the Voice Activation Level, and then try speaking again. When you feel that Internet Phone responds correctly, you are ready to go on.

4	Deselect Set Voice Activation Level in the Options menu.

When you speak into the microphone, now or during actual conversation, do not speak too close to the microphone. The voice level is a good indication of this: if it reaches far into the red zone, it is too high. Sometimes this will not work, and you will need to change your microphone's gain level to fix this problem. The software that is bundled with your audio board should be used to do this.

Internet Phone saves the current Voice Activation level to disk, so there is no need to repeat this process again unless you change your audio input device or unless it seems the Voice Activation interface is not working smoothly.

 Connecting to an Internet Phone Server

Before you can really start using Internet Phone, you must be connected to the Internet via a TCP\IP connection, or a modem SLIP\PPP connection of 14,400 baud or higher.

Before proceeding, make sure your Internet connection is in order.

Now we can try to connect to an Internet Phone server. By connecting to such a server, you enter the Internet Phone network. The Internet Phone network is your global phonebook, and presents you with an updated list of topics and on-line Internet Phone users. You must connect to an Internet Phone server to be able to talk over the Internet.

To connect to an Internet Phone Server,

Choose Connect To Server from the Phone menu.

The Connect dialog box opens up.


 Connecting to an Internet Phone Server

    Click on a part to get more information about it.

Internet Phone offers a list of Internet Phone servers world-wide for you to choose from. You can connect to the Internet Phone network through ANY of these servers.

The first time you run Internet Phone this dialog box automatically appears.It is used to locate an Internet Phone server, in case you do not know the address of one. The next times you try to connect to the Internet Phone, another dialog box will appear first, one that lets you connect directly to the Internet Phone (see the next topic).

Remember that you can connect to any of the servers, even if they are in another country. Of course, if you want to maximize performance, it is recommended that you connect to one in your vicinity.

1	Select your state or country from the State list.

2	Select a server in from the Server list.

3	Choose "OK".

The Internet Phone Connect dialog box appears, and the address of the server you selected is entered in the Internet Phone Server box.

Updating the Internet Phone Server List

You can download an updated list with more Internet Phone servers at our Web server.

Our Web Server is at http://www.vocaltec.com/

Download the file containing the updated list (ircsrvrs.ini), and replace the older one in your Internet Phone directory.

Now you can run Internet Phone and use the updated server list.


STATE

This box lists states and countries. If your country is not on the list, you can choose a country that is geographically close to yours.


INTERNET PHONE SERVERS

This box gives a list of Internet Phone servers in the state or country selected in the STATE box.


SHORT DESCRIPTION

This box displays short description of the selected Internet Phone server.


 Connecting to an Internet Phone Server

        Click on a part to get more information about it.

This dialog box is used to connect to an Internet Phone server. If you want to access the list of Internet Phone servers dialog box again, choose the Servers button.

It is also possible to type the address of an Internet Phone server directly into the Internet Phone Server box.

After you have located a server, choose "OK" to connect to it.

Internet Phone now tries to connect to the Internet Phone server. Notice the IPS indicator: it blinks in yellow while the connection is in progress, and when connection is established, it turns green.

When Internet Phone manages to connect to the Internet Phone server, the message "CONNECTED TO SERVER" appears on the message line. You are now connected to the Internet Phone network and can call and talk with persons over the Internet.


 Calling a Person

Internet Phone users locate each other through a list of topics. Any person can create a new topic or join an existing one. You can browse the topic list and locate a person you want to call. Later, you can use the Quick-Dial buttons to try and call a person directly, without having to locate him or her  in the topic list.

To browse the available topics and locate a person,

Choose Call from the Phone menu.

If one of the Quick-Dial buttons already holds the person's name,

Simply choose the button to call the person.


  Locating a Person

The Call dialog box is used to call persons over the Internet. It is also used to join topics and see who is listed under them. The first time you run Internet Phone, it lists you under the topic "General".

            Click on a part to get more information about it.

The name "General" should appear under the Joined Topics list. If you have joined other topics, they should also appear under this list. The selected topic is highlighted. If there are persons listed under this topic, they will be listed on the users list (under Name).

If you want to call one of the persons on the users list, select the person and then choose "OK".

If you want to look for other persons, or if there are no persons under the selected topic, you can select another topic and try looking under it.

If you want to join more topics, do the following:

To join another topic,

1	Choose the Join Topic button.

Another dialog box opens up. This dialog box displays all the topics now available.

2	Choose one of the topics and then choose the Join button.

We are now back with the first dialog box. The topic you selected is added to the Joined Topic list, and the name of the other persons listed under this topic are displayed on the second list.

3	You can now join other topics, if you wish. You can join up to ten topics at any one time. To see who is listed under one of the topics, select it in Joined Topics list, and the names appear in the users list. To remove your name from a topic and the topic from the Joined Topics list, choose the Leave Topic button.

Once you have joined topics, you can speak with one of the other persons connected to these topics. You are now listed under this topic when other persons join it, and they can start calling you.


NAME

This box displays the name of the selected user. You can also type the starting letters of a users name to locate him or her in the users list.


USERS LIST

This box list the users under the topic selected in the Joined Topics list.


JOINED TOPICS LIST

This box list the topics you have joined. You can join up to ten topics at any one time.


SHOW ALL USERS IN JOINED TOPICS

Select this option to view in the the users list all of the users listed under all the topics you have joined, and not only the users in the selected topic.


USER INFO

This box displays the user information of the user selected in the users list. Note that only part of the comment line about a person is displayed. To view the full comment, use the Internet Phone Information window.


JOIN TOPIC...

Choose this button to open a dialog box with a list of all the currently available topics, letting you join new topics.


LEAVE TOPIC

Choose this button to exit the topic that is now selected in the Joined Topics list. It removes your name from the list of users under this topic.


SORT USERS BY...

Sets the way users are sorted in the users list.


  Using a Private Topic

If you want to use Internet Phone only for your private conversations, you probably don't want to be bothered by calls from all the other Internet Phone users. Private topics are what you need: these "unlisted" topics cannot be seen on the topic list, and can be accessed only by users that know the exact name of the private topic. If you try to join a private topic that does not exist, it is automatically created.

To create or join a private topic,

1	In the Call dialog box, choose the Join Topic button.

The Join Topic dialog box opens.

2	Type in the name of the private topic in the Topics box.

3	Choose the Join Private button.

If there is no such private topic, it will be created.

4	If you do not want to be bothered by unwanted called, you should remove your name from the public topics, especially from the "General" topic. To do this, choose each topic from the Joined Topics list, and then choose the Leave Topic button.

5	Now you can close the dialog box by choosing the Close button.

6	When the desired person also joins the private channel, his or her name will appear on the user list. Select it and choose OK to call the person.

Now you are listed under your private topic. Of course, if the other persons you want to talk to do not know the exact name of the private topic, they will not be able to reach you! (you should decide on a name beforehand). Remember that when you connect to the Internet Phone network, you automatically get joined to the topics you were connected to when you left. If all you want to do is make private conversations, make sure you are only joined to the private topic. You will automatically connect to this topic each time you connect to the Internet Phone network.


 Calling a Person

After you click on a Quick-Dial button, or choose a name from the Call dialog box user list and choose OK, a call starts to the selected user.

The image on one of the Quick-Dial buttons will be animated and you should hear a ringing sound. If you don't hear anything, check if your speaker is connected properly.

Button mode	Meaning
	Not in use. The button is not in use.
	Making a Call. You are trying to call the person whose name appears under this button.
	Receiving a Call. The person whose name appears under this button is trying to call you. You can receive the call by selecting the button.
Calling another person with Internet Phone is just like calling someone over the phone: the line may be busy, or the person may not wish to speak with you.

If the person does answer, the message "CONNECTED" appears and conversation starts.


  Conversation

Conversation now starts, and as you will see, speaking over the Internet is fun and easy.

During conversation, you and the other person take turns speaking (this is the only difference from a "real-life" telephone conversation).

One of the Quick-Dial buttons is used for interaction with the other person. The person's name button is now displayed under the button, and the button changes its appearance to indicate who is now speaking.

Button mode	Meaning
	SPEAK mode. When in this mode, what you say is transmitted over the Internet to the other person's system.
	LISTEN mode. When in this mode, what the other person says is transmitted over the Internet to the your system and played on your speaker. You should not try to speak now.
	IDLE mode. When in this mode, nobody is speaking. You or the other person can start speaking.
Hold the microphone close to your mouth and speak clearly. When you finish speaking, the other person can respond.

Be careful not to speak too close to the microphone, or your voice will sound high and distorted on the other side. Make sure that the voice level (bright green bar) does not reach deep into the red zone. If it does, your voice is too high.

If the Voice Activation interface is not working smoothly, you can change the Voice Activation level by dragging the knob to lower or raise it.

To end the conversation,

Choose Disconnect From Server from the Phone menu.

The conversation ends.

When you exit Internet Phone, it automatically disconnects from the Internet Phone server. You can also manually disconnect by choosing Disconnect From Server from the Phone menu.


  Full Duplex Conversation

If your audio board supports full duplex audio, or if you have two standard (half duplex) audio board installed, then you can conduct full duplex conversations. Full duplex conversation is identical to one with a real telephone - you and the other person can speak at the same time. There is no need to take turns speaking. Of course, to be able to conduct such a conversation, both of your systems should support full duplex audio.

Before you call the other person, switch to full duplex mode (you can also try switching between half and full duplex modes during conversation).

To switch to Full Duplex mode,

Choose Full Duplex from the Options menu.

If Internet Phone is not set to Full Duplex audio, a message box will appear. To set it to Full Duplex audio, either choose the Test button in the box, or choose Test System Configuration from the Options menu.

Now you can call the person.

When you connect to the other persons system, the status bar should indicate Full Duplex. If it indicates Local FDX, then the other persons system does not support full duplex audio, and you will not be able to conduct a complete full duplex conversation. In such a case, you still have the advantage of being able to burst into the other users speech without having to select the users Quick-Dial button.

Conversation

During conversation, one of the Quick-Dial buttons is used for interaction with the other person. The person's name button is now displayed under the button, and the button changes its appearance to indicate who is now speaking. Unlike half duplex conversations, there are only Idle and Speak modes. When the other person is speaking, a small speaker symbol appears on the upper left corner of the Quick-Dial button.

Button mode	Meaning
	SPEAK mode. When in this mode, what you say is transmitted over the Internet to the other person's system.
	Idle mode. When in this mode, you are not speaking.
Hold the microphone close to your mouth and speak clearly.

NOTE

During a full duplex conversation, you may encounter a feedback problem: The sound will reverberate and become incomprehesible (If the other user has half duplex audio, then the other users speech may get cut constantly). This happens because the incoming sound played on your speaker is recognized as speech by the Voice Activation interface, and is sent back to the other user. To prevent this problem, we recommend using a handset or earphones instead of a speaker. If you don use a speaker, try to lower the volume of your speaker, and to lower the Voice Activation level to a level that does not respond to the sound coming from the speaker.

To end the conversation,

Choose Disconnect From Server from the Phone menu.

The conversation ends.

When you exit Internet Phone, it automatically disconnects from the Internet Phone server. You can also manually disconnect by choosing Disconnect From Server from the Phone menu.

The Nick Name you entered is not valid.

 Type in another Nick Name. It should be up to 9 characters long, and should include only letters, digits and these characters:  - [ ] ` ^ { } .


"This user is not a registered user, and has no fixed Internet Phone code. The button will be cleared when Internet Phone is exited."

You have set one of the QuickDial buttons to point to an unregistered Internet Phone user. Since unregistered users have temporary access codes, the button will not point to the unregistered user as soon as he reloads his Internet Phone. Therefore, the button will be cleared when Internet Phone is exited.


"Unable to copy registration file."

Internet Phone could not create a copy of the registration file in your Windows directory.

 Make sure you have the correct WRITE privileges in your Windows directory.

For information about how to order the full version of Internet Phone, see How to Order a Registration Code.


"Unsupported TCP/IP WINSOCK.DLL version, error code [...]."

Internet Phone was set up to use the TCP/IP network protocol for transmitting, but the WINSOCK.DLL module of the correct version was not found. WINSOCK.DLL is a standard component of TCP/IP networking software for windows packages, which is needed by Internet Phone. Internet Phone needs WINSOCK.DLL version 1.1.

Replace your current WINSOCK.DLL with a WINSOCK.DLL compatible with version 1.1.


"User Information will be updated on the server only on reconnect."

You have updated your user information in the User Info dialog while being connected to some Internet Phone server. As your user information is sent to the server only during the initial connection phase with the server, your revised user information will be updated in the Internet Phone Network only upon the next reconnection to a server.


"You are already connected to the server [...] Choose 'Yes' to disconnect and then connect or 'No' to stay connected."

You have chosen to connect to an Internet Phone server but you are already connected to one. You can either have Internet Phone disconnect from the current server and then connect to the new server by selecting Yes, or stay connected to the current server by selecting No.


"You must specify at least your Nick Name."

The only mandatory item to be filled in the User Info dialog box is the Internet Phone Nick Name, which is the user name other persons will see when they browse through the Call dialog box.

We suggest that you type in all your correct user information, as this is the information available to other Internet Phone users who talk to you through Internet Phone.


I don't hear the Attention, Ring, Call and Busy sounds

Make sure the Use Wave Audio option in the Preferences is on.

If it is on, then the audio device in your system is probably being used by another application.


The Volume control does not work

Your sound device does not support software volume control.

Another reason why the volume control does not work might be that Microsoft's Wave Mapper is installed on your system.

To remove Wave Mapper, remove it from the Control Panel's Drivers section.


When getting a call, I only get an internal beep and a "NO AUDIO" message

Some other application is using the sound device. Only one program at time can use the sound device.


After I stop speaking, "SPEAK" mode stays on

Your microphone is too sensitive.

Raise the Voice Activation level.


When I speak, Internet Phone toggles quickly between SPEAK and IDLE modes

Adjust the Voice Activation level.


When I speak, the other user hears "clicks" between words

Raise the Voice Activation level.


When I open an application while another user speaks, I can't hear the user

This is a well known problem with Windows. Whenever the "Hourglass" mouse cursor appears, it means that one application is running exclusively, thus Internet Phone does not get time to process more voice.

Try to avoid operations that hold up the computer for a long time while you are in conversation (operations like loading applications, recalculating spreadsheets, etc.)


When I use a full-Screen DOS application, sound is cut off, or does not play at all

Internet Phone does not get enough time to process the voice and play it.

You should do one of the following:

(the first two options are set using PIFEDIT)

Make sure your DOS application is not flagged to run Exclusively (if it is, deselect the Exclusive check-box).

Set a lower priority to the DOS box (by clicking on "Advanced", and typing a lower value in the Priorities box)

Set a higher priority to the Windows in Background (in the Control Panel/386 enhanced options)

Run your application in a Window, instead of full-screen.


Your voice sounds a little too loud and distorted on the other side

If the person you are speaking with complains that your voice sounds too loud or distorted, it is possible that your microphone is too sensitive or the level of your voice is too high.

 Try to lower the level of your voice or speak a little further from the microphone. The graphic audio level (bottom-right corner of the window) should not be exceed the green area. It it reaches into the red section, it is too high.

 If this does not work, it is possible that your microphone's gain level is not at the optimal level. Check your audio card's bundled software for the gain level setting. Try to raise or lower it.

 You can use the Windows Sound Recorder or a similar utility to record and playback your voice and hear if it comes out right. Note however that the voice quality on the other side may be different if the other person is using a different audio board.


The other person's voice sounds too loud and distorted

The problem is probably on the other person's side. Inform him or her about it. It is possible that the other person's microphone is too sensitive or the level of his voice is too high.

You can offer him the following advice:

 Tell the person to try and lower the level of voice or to speak a little further from the microphone. The graphic audio level (bottom-right corner of the window) should not be exceed the green area. It it reaches into the red section, it is too high.

 If this does not work, it is possible that the other person's microphone's gain level is not at the optimal level. Tell the person to check the audio card's bundled software for the gain level setting, and to try raising or lowering it.

 The other person can use the Windows Sound Recorder or a similar utility to record and playback his or her voice and hear if it comes out right. Note however that the voice quality on the other side may be different if the other person is using a different audio board.


Both users hear an increasing feedback whistling sound

The whisling sound is caused because of the close proximity between your microphone and the other user's system (or the other way around). Because of the sensitivity of the microphone, it registers the sound that is being played on the other user's speaker, and the whistling sound starts.

If you are in Full Duplex mode, the problem is probably caused because the incoming sound played on your speaker is recognized as speech by the Voice Activation interface, and is sent back to the other users system.

Lower the volume on the other user's system (and on yours too, if necessary).

If you are in Full Duplex mode, lower the volume of your speaker, and raise the Voice Activation level. We also recommend using a handset or earphones instead of speakers.


I hear a feedback sound when conducting a full duplex conversation

The feedback sound is caused because the incoming sound played on your speaker is recognized as speech by the Voice Activation interface, and is sent back to the other users system.

Lower the volume of your speaker, and raise the Voice Activation level. We also recommend using a handset or earphones instead of speakers.


The other user has half duplex audio, and his speech gets cut constantly

The problem is caused because in Full Duplex mode, the incoming sound played on your speaker may be recognized as speech by the Voice Activation interface, and is then sent back to the other users system, thereby interrupting his or her speech.

Lower the volume of your speaker, and raise the Voice Activation level. We also recommend using a handset or earphones instead of speakers.


The other user is speaking, yet I hear nothing

If you are using two audio boards, the problem is probably caused because the microphone and speakers (or other input and output devices you use) are not connected to the correct audio boards.

Select Preferences from the Options menu. In the dialog box, check which audio board is under Speak and which is under Listen. Make sure that a different board is liste under each. Now connect the input device to the board listed under Speak, and the output device to the board listed under Listen.


"USER NOT ACCESSIBLE"

Although listed on the network, the other person is not accessible.

The most plausible explanation is that the person disconnected (intentionaly or due to a hardware or software failure) from the network just after you started your call. A person's name is sometimes listed for a few seconds even after the person is no longer available. Another possibility is that there is a problem in establishing an actual physical connection between you and the other person, although you are both connected to the network.


"BAD IP ADDRESS"

To connect to a remote host running Internet Phone, Internet Phone needs to determine the IP (Internet Protocol) address of that host.

You have tried to call some user, and Internet Phone could not properly resolve his network address or has a corrupt IP address cached in memory.

 Clear the users QuickDial button, and try calling him again.


"CANT GET IP ADDRESS"

To connect to a remote host running Internet Phone, Internet Phone needs to determine the IP (Internet Protocol) address of that host.

You have tried to call some user, and Internet Phone could not resolve his network address.

This error could occur if  theres a problem with a domain name server your host depends on or if your link to the Internet is down.

 If you have a dialup link (PPP or SLIP) to your Internet service provider, make sure you are connected to your service providers host by trying to ping it (Using the Ping utility provided with your TCP/IP networking software).

 If you have a direct Internet link, make sure your gateway to the Internet is ok.

 To make sure if you are connected to the outside world, simply ping a remote host such as the Internet Phone server youve been trying to connect to.

 Now try calling the user again.


"CANT RESOLVE HOST"

To connect to a remote host running Internet Phone, Internet Phone needs to determine the IP (Internet Protocol) address of that host.

You have tried to call some user, and Internet Phone could not resolve his network address.

This error could occur if  theres a problem with a domain name server your host depends on or if your link to the Internet is down.

If the problem occurs only intermittently, switch the DNS operation to synchronous in the Preferences dialog box by toggling off the asynchronous DNS operation and try again.

 If you have a dialup link (PPP or SLIP) to your Internet service provider, make sure you are connected to your service providers host by trying to ping it (Using the Ping utility provided with your TCP/IP networking software).

 If you have a direct Internet link, make sure your gateway to the Internet is ok.

 To make sure if you are connected to the outside world, simply ping a remote host such as the Internet Phone server youve been trying to connect to.

 Now try calling the user again.


"RESOLVING IP ADDRESS"

Internet Phone is busy resolving the IP address of the user you are trying to call.


"NETWORK UNREACHABLE"

Internet Phone tried to connect to a remote Internet Phone which belongs to an IP network which is not accessible from your own IP network. This could occur if the remote user's IP address configured in your address book is wrong, or if your TCP/IP software is not configured to route packets to that remote network.

Please validate the IP address of the remote user and ask your network administrator to make sure there's a network route to the remote network.


"HOST UNREACHABLE"

Internet Phone tried to connect to another Internet Phone which runs on a host which isn't currently accessible from your own host. This may happen if the remote host is not currently connected to the network.

Please make sure the remote host is connected to the network.


"NETWORK ERROR!"

Some network related error occurred when Internet Phone tried to send or read data from the network.

Please make sure your networking software and hardware are properly configured.


"FULL DUPLEX FAILED"

You tried to conduct a conversation in full duplex mode, although Internet Phone could only detect half duplex audio on your system.

Switch back to half duplex mode by deselecting the Full Duplex option.


"CONNECTION LOST"

You were talking to another user but his transmissions have stopped. This could happen if the other user's computer crashed or was reset in the middle of the conversation, and cannot transmit any more.

It is also possible that there is a communication problem between your system and the other user's system.

Try to call the user again.


"AUDIO DEVICE BUSY"

Internet Phone was trying to play or record sound using your audio device, but the device was being used by another application. When Internet Phone tries to play the audio indications (ring, busy, etc.), and the audio device is busy, it will beep using the internal PC speaker instead.

Quit or stop any other application that uses audio, before trying to talk with Internet Phone or install another audio card in your computer.

The other user will get an error message and the call will disconnect.


"BAD AUDIO FORMAT"

Internet Phone could not perform a conversation with another Internet Phone because of incompatible audio formats. For example, this could happen if one side uses only a VocalTec Compression Card which supports only the Compressed VDF format, while the other side has some other audio card.

Make sure both sides of the conversation use a compatible audio card.


"NO COMPRESSED AUDIO"

You have tried calling a remote user, but your InternetPhone couldnt detect any audio device which supports the audio formats needed by InternetPhone in order to perform either hardware or software audio compression.

 Make sure you have an audio device which supports at least PCM 11Khz audio.


"UNKNOWN DATA"

Internet Phone has received audio data of an unsupported format from the remote Internet Phone at the other side of the conversation. This might happen if the remote Internet Phone is of an another version, which is incompatible with your version of Internet Phone.


"UNKNOWN ERROR"

The connection was disconnected by the other user's Internet Phone because of an error unrecognized by your Internet Phone (the other Internet Phone is probably from an incompatible version).

Try and call the user again. If the problem repeats, check if you are using the latest version of Internet Phone.


"REMOTE UNKNOWN DATA"

The remote Internet Phone at the other side of the conversation has received audio data of an unsupported format from your Internet Phone. This might happen if the remote Internet Phone is of an another version, which is incompatible with your version of Internet Phone.


"REMOTE AUDIO BUSY"

You have tried calling a remote user, but the Internet Phone on his/her side could not detect any available audio device.

 Make sure the other side has a free audio device available to his Internet Phone and try calling him again.


"REMOTE UNKNOWN ERROR"

The connection was disconnected by the other user's Internet Phone because of an error unrecognized by your Internet Phone (the other Internet Phone is probably from an incompatible version).

Try and call the user again. If the problem repeats, check if you are using the latest version of Internet Phone.


"NOT AN IPHONE USER"

The user that you tried to call, although on the users list, is not running Internet Phone. There is therefore no way to reach him or her.


"REMOTE BAD AUDIO FMT"

Internet Phone could not perform a conversation with another Internet Phone because of incompatible audio formats. For example, this could happen if one side uses only a VocalTec Compression Card which supports only the Compressed VDF format, while the other side has some other audio card.

Make sure both sides of the conversation use a compatible audio card.


"REMOTE CPU TOO SLOW"

Internet Phone could not perform a conversation with another Internet Phone because the remote computers CPU is too slow to support the software compression algorithms needed for conversation over the Internet.

Make sure both you and the remote user have the VocalTec Compression Card (which performs hardware audio compression thus unloading the CPU) or make sure that the remote user runs his Internet Phone on a computer with a more powerfull CPU.


"CPU TOO SLOW"

Internet Phone could not perform a conversation with another Internet Phone because you chose to disable the software compression feature after the computer speed test failed (As the test found that your computers CPU is too slow to support the software compression algorithms needed for conversation over the Internet).

You can try using the software compression by selecting the Test Computer Speed option from the Options menu, and choose NOT to disable the software compression once the test completes.

If you find out that your computer is indeed too slow to support the software compression, make sure both you and the remote user have the VocalTec Compression Card (which performs hardware audio compression thus unloading the CPU) or run your Internet Phone on a computer with a more powerfull CPU.


The other person's voice gets cut off every now and then

One of the following may be the cause of the problem:

Voice Activation problems

Ask the other person to raise the voice activation level

Packet loss

(due to low speed/quality modem connection or due to Internet overload on the path to the remote user (for example, in the service provider's computers at either side).

Check the amount of packet loss using the view statistics command. Ask the remote side if he has any send errors in his statistics. Send errors mean that the modem connection cannot handle the audio bandwidth, so a higher baud rate modem should be used (at least 14400 baud).

CPU overload

Try running less concurrent applications

Try using hardware compression

Use a computer with a stronger CPU.


I get disconnected from the server during a session

If you suddenly get disconnected from the Internet Phone server (when refreshing the topic list, for example), the following may be the cause:

The server may be overloaded.

There may be a problem with the Internet connection: with the modem connection or with the Service provider's connection itself.

Try connecting to a different Internet Phone server

If this fails, make sure your Internet connection is in order.


The topic scan (Refresh button) gets stuck

Topic scan overloads both the network and the Internet Phone server. So it could become very   unresponsive up to the point of not advancing.

Disconnect from the server and reconnect to it.


I get a Nick Name clash message from the server

There is another person that uses the same Nick Name as you.

After an unorderly disconnect from the Internet Phone server, which takes time to detect the disconnect.

 Change your Nick Name by selecting the User Info item from the Options menu.

 Or wait a bit and try connecting again.


I get a registration violation message

Someone else is using your unique registration code. It is not possible for more than one person to connect to the Internet Phone Network with the same registration code.

Don't spread your copy of Internet Phone! It is both illegal and immoral!


Problems with TIA

Since TIA users have the address of the UNIX host they're connected to, multiple TIA users cannot run Internet Phone while connected to the same UNIX host.

A TIA user can only CALL others but not be called by them, since the TIA on the UNIX side doesn't listen to the Internet Phone socket.


"You are already registered. Would you like to register again?"

Internet Phone detected that your copy of the product is already registered.

 Choose Yes to perform the registration process again.

 Choose No to abort the new registration process and keep using your existing  registration.


"Internet Phone will now test your system performance, please close all background DOS applications before selecting OK."

Internet Phone performs an automatic test of your CPU performance,

to find out if your computer is powerful enough to execute the advanced software

audio compression algorithms used by the Internet Phone.

Close all background DOS applications and any other CPU consuming application.

Choose OK to start the test.


"Your system passed the performance test. It scored [...], which is more than the recommended performance index ([...] for half duplex and [...] for full duplex)."

Internet Phone performed the automatic test of your CPU performance, and detected that your computer is powerful enough to execute the advanced software audio compression algorithms used by the Internet Phone, in both half and full duplex modes.


"Your system passed the performance test for half duplex. It scored [...], which is more than the recommended half duplex performance index ([...]), but less than the recommended full duplex index (65). You might have performance problems in full duplex."

Internet Phone performed the automatic test of your CPU performance, and detected that your computer is powerful enough to execute the advanced software audio compression algorithms used by the Internet Phone, in half duplex mode. It may not be powerful enough to run Intrernet Phone in full duplex mode.


Your system Internet Phone performance index is [...], which is less than the recommended performance index ([...] for half duplex and [...] for full duplex). You might have system performance problems while speaking with other users."

Internet Phone performed the automatic test of your CPU performance, and detected that your computer might not be powerful enough to execute the advanced software audio compression algorithms used by the Internet Phone, in either half and full duplex modes.

If your performance index is close to the recommended performance index, you should try calling another user with your Internet Phone and make sure you have no performance problems during the conversation. It is recommended you quit other applications when running the Internet Phone.

If your performance index is much lower than the recommended performance index, your system will probably freeze during an Internet Phone conversation.

If you are a VC Card (Vocaltec Compression Card) owner, and you wish to disable the software audio compression option and use only the VC Card, you should:

1	Quit Internet Phone.

2	Modify the following entry in the IPHONE.INI file (which resides in your Windows directory) :

[Audio]

FormatDisabled17=NO ->Change from "NO" to "YES"

3	Now rerun Internet Phone.

Note that while this option is set to YES, you can only have Internet Phone conversations with other owners of the VC Card.


"Registration completed, Internet Phone will now exit. Reload Internet Phone for the new registration to take effect."

Internet Phone has successfully completed performing the registration process, and is now ready to be rerun.

Choose OK and Internet Phone will exit.

Run Internet Phone again for the registration to take effect.

Memory Problems

If you get an "Insufficient memory to run application" message, although you still have enough free memory, the problem is probably due to a lack of DOS memory. Most applications require at least 0.5K of DOS Memory - and it is a scarce resource. A simple soutClose other application. About Internet Phone. locate memory section. network drivers audio cards etc. Try changing the order of loading

A simple solution is to close one of the open applications and run Internet Phone. Some applications (including Internet Phone) use more DOS memory than is necessary. Try to open the applications in a different order.

To make sure the problem is DOS memory, choose About Internet Phone from the Help menu. In the About dialog box, locate the memory section. It reports how much DOS memory was free before Internet Phone started, and how much is free now.

It is possible that network drivers or audio board drivers are using up your DOS memory. Check if you can close or change them.


Communication with the server seems extremely slow

If actions such as connecting to the Internet Phone server, joining topics or refreshing the topic list seem slower than usual, it is possible that the server you are connected to is overloaded.

 Choose View Log from the Options menu. Search for a message from the server reporting overload.

 Disconnect and reconnect to another server.


Nobody is on-line on the Internet Phone network

It is possible that nobody is on-line at the moment. A more probable explanation is that the Internet Phone server into which you connected is not properly connected to the server. View the log. It reports how many servers on the network.

 Choose View Log from the Options menu. Browse the messages back to the point you connected to the server. When you connect to a server, It reports how many users and other servers are connected. If no other servers are connected (or if their number is low - less than 100), the server is probably temporarily disconnected.

 Try connecting to another Internet Phone server.


"Internet Phone will now test your system audio configuration. Please stop all applications that use audio before selecting OK. You can repeat the test later by choosing Options/Test System Configuration."

This message appears before the system audio configuration test is started. This test checks your audio devices to detect if full duplex mode is possible.

 Close all the applications that use audio. If you dont, the audio configuration process will fail.


"Another application is using the audio device. Stop the audio in this other application and select OK to try and test again."

Internet Phone detected another application that is using your audio device. Please close all applications that use audio, if you want to successfully finish the audio configuration process.

 Close all the applications that use audio. If you dont, the audio configuration process will fail again.


"Full duplex audio configuration detected. You will be able to have full duplex conversations if the Options/Full Duplex option is selected. If your audio configuration changes repeat the test by choosing Options/Test System Configuration."

Internet Phone detected on your system an audio device that supports full duplex audio. You will be able to use this mode to conduct full duplex conversations.


"Half duplex audio configuration detected. You will not be able to have full duplex conversations. If your audio configuration changes repeat the test by choosing Options/Test System Configuration.

Internet Phone detected on your system an audio device that supports only half duplex audio. You will not be able to conduct full duplex conversations. If you install a device on your system that does support full duplex, run this test again to configure Interent Phone to full duplex audio.


"Internet Phone found that you have more than one audio device installed. Select OK to choose the preferred devices for Speak and Listen. You can repeat this procedure later by choosing Options/Preferences."

Internet Phone detected on your system two audio devices. You will be able to use them to conduct full duplex conversations. Select OK to open the preferences dialog box.

In this dialog box, set the following:

 Under Speak, set one device as your input device. You will need to connect your microphone or other input device to this board.

 Under Listen, set another device as your output device. You will need to connect your speakers or other output device to this board.


Your system does not support full duplex audio.

Internet Phone is configured only to half duplex audio, and therefore cannot switch to full duplex mode.

 You can override this message and switch to full duplex mode by choosing Continue. If you do so, you will probably not be able to conduct conversation at all.

If you do not want to see this message box again, you can select the Dont display this message again option. If you do so, this message will reappear only after you run the system configuration test again.

 If your system does support full duplex audio, you should rerun the system configuration test by choosing the Test button. This will start a test that will try to detect a full duplex audio device on your system.


Using Internet Phone Over SLIP/PPP Connection

The Internet Phone requires that your modem is configured properly it order to work.

Checking your modem configuration:

1  If your modem is an external modem, then you must make sure that your serial port has a proper UART, that is capable of high-speed transmissions. The normal UART is called 8250. While it may be enough for DOS programs to communicate, its performance is too low for high-speed transmissions under Windows. You must have 16550 UART in order to use the full bandwidth of your modem.

To check the UART type, run MSD from DOS prompt. After MSD finishes examining the system, select "COM Ports". For each COM port on the system, MSD will show whether it uses the 16550 UART or not.

2  If your modem is internal, then it probably has the 16550 UART built in. Some modems require a vendor-specific driver. Make sure to use the latest version of the vendor's drivers for the modem.

3  Make sure to have the following line in your SYSTEM.INI file, under the [386Enh] section:

COM2FIFO=1	(assuming your modem is on COM2).

    Note that you cannot use "Yes", or "True" for the value, although it is incorrectly documented so in the SYSINI.WRI file. The value must be "1".

4  In order to use Full-Duplex mode on you must disable modem compression. This might degrade somewhat text transfer, but will improve binary transfers (pictures, compressed files, binaries, etc). There is no general way to disable modem compression. It depends on your modem and Winsock stack. First check your Winsock documentatioin and setup to see if a "Modem Compression" option exist, and if so, then disable it. Otherwise, you'll need to add an initialization command to disable modem compression. The initialization string for Hayes-compatible modems (most of the modem in the market) start with the letters "AT", and thus called AT commands. Your modem initialization string might look like "ATZ&C1&K3". Depending on your modem configuration, it can be much longer. The AT-comand to disable modem compression is different for different type of modems. For most modems, the command is AT%C0. e.g. modems of the following companies: AT&T, Boca, Zoom, Compaq, Gateway2000, Intel, NEC, Supra, Motorola and others. USRobotics, Zyxel: AT&K0

For other modems, check the documentation.
