Ok.. here is the situation... When I register to the server, I find that the Accept Pattern are "blank" while when I register using Windows Messenger, it shows a list of accept patterns that Windows Messenger client can accept.

My question is how can I set the Access Patterns ?

Although my application is getting registered but on sending INVITE, server logs indicate error 488 i.e. "Not Acceptable Here".

Anyone had this experience ?

I am using SIP Plugin 3.0
