Title: MS messenger SIP session is very strange???

Hello my friends,
  I have found very strange SIP traffic between two MS messenger when they are trying to talk.
I need you my friends to help me out.
  I am using MS messanger Ver 4.6.
  I use Messenger A to invite Messenger B to join the talk. But in the SIP traffic between the two messengers, it is
Messenger B which sends the INVITE SIP message to Messenger A, why is that?
  Other question is: which ports are they using for SIP communications?

Thank you,

Roland
