Hi, I think the msn client uses a proprietary protocol NOT SIP. Try to google for msn protocols. There seems to be analysers for that protocol out there.
Windows messenger uses SIP.

Also, i cannot find any sip protocol, but from the site you told me(http://www.hypothetic.org/docs/msn/client/invitation_types.php), it uses sip protocol with video conversation. i don't know where i can find this protocol to see negotiation of connection; like QCIF, CIF, bit rates, etc. Could you plz help me with this stuff, all i need is just little help to analyze frames. and whether i can do anaylize video packets or not.
