Making Your First Call

You are now ready to make your first call. Perform the following procedure to make an Internet Phone call from the Community Browser window.

To make your first call

1. Run Internet Phone. The Internet Phone window appears on the screen.
2. Click the Community Browser tool button.
3. In the Community Browser window, you automatically join one of the Public Chat rooms.
4. On the left-hand side of the chat room is a list of currently on-line Internet Phone users. Call a person from the user list in one of the following ways:

	Double-click the person's name.
	Right-click the person's name and then choose Call.

5. The call is in progress and Internet Phone Release 5 attempts to reach the person you selected. The Animated Assistant shows that you are connecting, and you can hear simulated telephone ringing sounds. If the person accepts your call, you can have a conversation.
6. Speak clearly into the microphone. Be careful not to speak too closely to the microphone, or your voice will sound high and distorted on the other side. Make sure that the Record Level bar in the Audio Settings of the Internet Phone window is always bright green and does not reach deep into the red zone. If it does, you are speaking too loudly.
7. End the conversation in one of the following ways:

	Click the Hang Up button in the Internet Phone window.
	Point to User in the Phone menu and choose Hang Up.

The conversation ends.

Conversation Modes

There are two modes of conversation: Full-Duplex and Half-Duplex. In a full-duplex conversation, both users can speak at the same time; in a half-duplex conversation, users take turns speaking.

In order to be able to conduct a full-duplex conversation, both users' systems must support full-duplex mode. A full-duplex sound card must be installed. If your system supports full-duplex mode, but the other user's system supports only half-duplex mode, Internet Phone will automatically switch to half-duplex.

During a conversation you can switch between full-duplex and half-duplex mode at will.

To switch between full-duplex and half-duplex mode

Point to Audio in the Options menu and choose Full Duplex depending on your requirement:

	When selected: Full-duplex mode. If both users' systems support full-duplex, both of you can speak simultaneously.
	When cleared: Half-duplex mode - both of you must take turns speaking.

At the bottom of the Internet Phone window, the Conversation Mode icon displays the current mode.

Full-Duplex Conversation

During a full-duplex conversation, both you and the other person can speak simultaneously, just as easily as if you were using a phone. Note that there can be a short delay before what you say is transferred and played on the other user's system.

The following events occur in the Internet Phone window:

	The Animated Assistant shows you are talking with each other.
	The Message line indicates the current mode of conversation. The different modes are:
	No one is talking Nobody is speaking. You or the other person can start speaking.	Talking What you say is transmitted over the Internet to the other person.	Listening What he or she says is transmitted over the Internet to you.	Both What you both say is transmitted over the Internet to each other.

Half-Duplex Conversation

A half-duplex conversation is identical in nature to a full-duplex conversation, except for the following:

1. During conversation, you and the other person must take turns speaking (more like using a ham radio than a telephone).
2. The Animated Assistant and the Message Line supply you with information about the remote side status. The message line indications are as follows:

3. You can interrupt the other person in the middle of speech.
   Press the Push to Talk button in the Audio Settings area in the Internet Phone window. Do not release this button until you wish to stop talking.
