Having a Conversation
Once you have your computer set up -- software downloaded, speakers and microphone or headset installed -- you're ready to start having conversations. And of course, the conversation starts with the Google Talk window.
Sign into your Google Talk program, and from the Google Talk window, select the person you would like to call. Remember that to select a person, you simply place your pointer over the person's name and wait for the pop-out window to appear.
To talk to others through Google Talk, they also have to be using the program, and they must also be onlein. If you try to call someone who isn't online, you'll receive a message telling you that.
From the pop-out menu that appears, click the Call button, shown in the figure below. This intiates a call to your selected friend.
Inside the chat window, you'll see a message that says you're calling someone. This will chage to show you're actually talking to the person or (if there's no answer) that you've left a voice mail, if you have.
When you're ready to end the call, just click the End Call button, shown below. (Hint: The End Call button replaces the Call button when the conversation is initiated.)
