[Serusers] windows messenger 5.1 and IM

[Yi Zheng]

I have two window messenger 5.1 clients on the same subnet as the SER server w/ pa module. They subscribe/notify to each other ok. HOwever they cannot IM each other. The callee, after receiveing INVITE, sent back a 100 trying, then 200 OK, and then immediately BYE. 
   
  I searched thru archives and looks like this is a known issue with wm. What is the solution or workaround to this?
   
  Here is the messages I captured:
