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.
Best regards
Anders

Ämne: Re: [Wireshark-users] capturing msn web cam traffic with wireshark.
can you guys give me your hand? b/c i don't have any other one who can help
me about these things.
i am currently a senior in an university, and trying to write a graduation
thesis about msn video conversation and its codec , frame rate, ...
and analyze the changes while i limit the bandwidth of connection..
a file i attach here is a capture file using msn video conversation.
i decoded it with RTP, in that way, i can find some frames with the payload
type unknown(72), i think these frames are the video frames, and can
calculate frame rates of video by counting these frames,
is that right?
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.
Sincerely.
