Maybe Windows messenger does complie to that ... but I dont know for sure. And 
I also dont
know where to get that kind of info. Anyway before I start adding 
"Subscription-State" headers
here is my current trace.
There are 3 machines:
10.41.2.41    Linphone Client
10.41.2.52    Windows messenger
10.41.2.53    SER SIP server

The content of the first 4 packets is about registering to SIP server.
After that subscription process starts up from windows messenger.
