Jingle was fippo's favorite VoIP protocol, but then he discovered RTMP.

<lynX> Is it correct that you can only Jingle with Google Talk users, but not with regular SIP/VoIP phones and installations?

<fippo> No. Jingle uses RTP for media, hence you can write a Jabber<->sip proxy and call SIP phones. I wonder if that even works using xmpp: addresses - sane SIP client implementations shouldn't care about the protocol prefix. Btw, jingle is a generic session establishment protocol which does not care much about what the sessions are used for - SIP reinvented using XMPP.
