[Serusers] Instant Messaging cannot work with Windows Messenger5.0

[KokMeng Loh]

Hi,

Unfortunately, I need to use application sharing and whiteboard as well. 
And that rules out eyeBeam. Now, I'm stuck with trying to get Windows 
Messenger to work. Windows Messenger 5.0 and above uses INVITE to start 
a messaging session. But it still use the MESSAGE request to send the 
actual message. The problem is that the callee sends a BYE immediately 
after sending an OK response to the INVITE. So, when the MESSAGE request 
comes in later, the callee responds with a "481 Call Leg/Transaction 
Does Not Exist".
