i knew you could do this but never tried. so i did it today and it works like charm.
If your like me and use GAIM as an IM client, then you might want to follow these instructions for setting up GAIM to use the GoogleTalk servers.
1. Click Accounts->Add (at the login screen)
2. Under the protocol dropdown choose “jabber”
3. Your screenname is everything before @gmail.com
4. Change server from jabber.org to gmail.com
5. Click show more options
6. Make sure “USE TLS if available” is checked.
7. Connect server should be “talk.google.com”?
8. Password is the same password that you use for gmail
Rock on!
afaik you can’t actually have voice conversations with gaim yet. They’re working on a different future release for that.
or you can follow instructions on this page:

since Gaim lead developer is working for google, he’ll develop a voice over service for gaim soon enough 😀
