Here is the procedures: 1) Sent SIP Subscribe , Request event is = Presence.winfo (Watcher info) 2) Received 202 - Accept. 3) Waited for SIP Notify message. 4) Nothing happened Again 1) Sent SIP Subscribe to add a buddy into my contact list, Request event is = presence. 2) Received 202 -Accept. 3) Waited for SIP Notify message, 4) Nothing happened In another scenario 1) Sent SIP Publish with my status in pidf+xml format 2) Received 202 -Accept. 4) Nothing happened Thanks a lot, Hassan _________________________________________________________________ R U Ready for Windows Live Messenger Beta 8.5?
