I apologize if this information is staring me in the face and I don't get it, but is is possible to do audio conference calls with KDE telepathy 0.6.0? If so, how do I do it?? If this is possible, my corollary question is what other types of clients can participate and/or start the call? In particular, I would be interested in Psi and Skype for windows.
thanks

1-1 calls work (ish, setup can be a pain, and even jingle can still have problems with firewalls etc.)
Theoretically it should work with any other client.

Conference calls do not. No-one has written the code to do it yet.
