Voice chat with Google talk user using Empathy Messenger

Few days back one of my unknown friend called me and asked to me that can we do voice chat on Ubuntu Linux with Google talk? and he told me that Pidgin and Gaim messengers don't support voice chat with Google talk in current release(Pidgin is working on video and voice support for details click on link).At that time I don't know its detail, After doing some search I got solution for this matter.

We can do voice with Google talk on Ubuntu using Empathy Messenger. Empathy Messenger consists of a rich set of reusable instant messaging widgets, and a GNOME client using those widgets. It uses Telepathy and Nokia’s Mission Control, and reuses Gossip’s UI. To Setup Empathy and Google talk click here
