SIP and XMPP is not the same discussion as H.323 and SIP. SIP and XMPP can 
co-exist very nicely and provide complimentary services while SIP is a 
replacement for H.323. There is no need to discuss whether we replace SIP with 
XMPP but do we want to support XMPP as well as SIP.  XMPP Jingle Signalling just 
puts SIP/SDP inside of an XMPP stream. It is rather trival for a client or 
server to support SIP as well as Jingle.

A good article on this subject by a Jabber guru:
