[Serusers] problem with IM b/w windows messenger 4.7 and 5.0

[Rao]

Jan, Ralph and Daniel thanks for your responses.
Here is some more calrification.

1) I am using windows messaeger 5.0 and MSN messenger.

2) The link Ralph provided only works for wondows XP.
   On one of my machines I am running windows 2000
   and would like to see IM work on win2K. I cannot
   find IM 4.7 for any version of windows except XP.

3) I can not get IM to work even when both
   machines are running messenger 5.0. Seems to be
   the same issue when one is running 4.7 i.e.
   maddr in route header is being ignored and ser
   tries to deliver it to the local machine and 
   tcp connect fails. 
   Has any one made IM to work b/w MM 5.0 

Following is a trace of a SIP message request that
has maddr in the Route request. Let me know if more
traces are needed.

So I have following questions

1) Can there be an maddr parameter in the Route
   header ? Cannot find an answer in RFC 3261.

2) In any case why can't we fix ser to interpret
maddr.
   windows OS is probably the most important OS 
   with which ser needs to support.

3) What is a better utility than ngrep to get traces
   which are better formatted. I have seen folks post
   very nicely formatted traces, what are they using.

Let me know  if I need to post these questions
on the development list.

Regards.

Rao.
