Even though google has not made this an official feature my friends and I have figured out how to conference call using google talk 
How to conference call:
Open up a copy of google talk on all computers with which you wish to conference. After one copy is opened make a new shortcut for google talk but at the end of it add /nomutex. If you installed it to the default folder then your shortcut should read “C:\Program Files\Google\Google Talk\googletalk.exe” /nomutex. Open 2 instances of the software on every user’s computer. After this start a chain: User 1 should connect on one instance to user 2. User 2 will connect on his second instance to user 3. User 3 will connect using his second instance back to user 1. With this chain everyone is connected to everyone.
Possible problems: Google will try to connect you with others on the same instance. To fix this just open a new instance. It seems that google will try to take calls on the newest IM client.
Note: You can also make a conference call with more people, just have need to have one less instance than the amount of people that exist.
Wow, do you really think anyone is going to do this? What crap. You should spend your time and effort convincing Google to add the feature.
This isn’t meant to be pratical. We just tried it out for fun.
hi, i am convinced that google talk is a really good IM. in addition to that, found this site called gtalkphone.com. now, it allows me to make PC to ordinary phone calls anywhere in the world and vice-versa. check it out! its cool!
Nice find! I just checked it out and it looks like a really useful service. Thanks for the tip Rickshaw.
