Anyone know if this update applies to Google Voice? And whether it will now be possible to initiate a standard RTP stream via XMPP? That would make SIP interoperability with Google Voice practical. At the moment it's held back by the fact that Google Voice requires some custom ICE packets to be exchanged on the RTP sockets before it will commence sending RTP. Which means there are no SIP clients that can talk RTP with Google Voice when the call is initiated over XMPP :(.
