I use Kubuntu 9.10.
KDE 4.4.1 and Kopete 1.0.0.

I configured Kopete according to:

Still I couldn't start using GTalk Audio Calls.

I was using Pidgin earlier. Now Pidgin freezes whenever I initiate a call.

So I couldn't use both Pidgin and Kopete for GTalk Audio.

Skype works perfectly for me.

Is there any jabber service or some other services that i need to run?

Please help.
