Google talk voice chat from linux

Hellow friends, To use voice chat from a linux machine to gtalk user from a windows system

Use jabbin from http://sourceforge.net/projects/jabbin

But i noticed that if the windows user is using googles client for gtalk the voice wont be audible eventhough pressing call button leads to ringing on the opposite end.

But if windows users uses jabbin's windows version at their end ,voice chat works fine .

here are the pictures to learn how to configure jabbin with in 5minutes. User interface is similar in both windows and linux(thanks to qt from trolltech)

Alternative is to use skype .
