IIRC, they still use RTP for audio (which is also used with SIP and
H.323); they just run the signalling over Jabber/XMPP.  Which seems
reasonable; otherwise they'd have ended up with two parallel setups,
one for SIP and one for Jabber.  To me, that seems a bit yuck, and
likely to be fraught with difficulty when one works and the other
doesn't, due to firewall problems or similar.

For most people, the alternative is Skype, which means being locked
into their proprietary protocols, which they seem unwilling to
document.  If it's a choice between the two, I'd prefer the one with
open specs.  And there are apparently Linux clients for XMPP/Jingle;
see, for example:
