Hi all,
Please confirm my understanding of subscribe for MWI. NOTIFY should not be
sent to a UA unless a SUBSCRIBE has been sent to it.
I'm doubting my understanding because I just got an asterisk server running
and it immediately sends a NOTIFY after I REGISTER with it. The NOTIFY does
not have "Subscription-State" header.
Request-Line: NOTIFY sip:[EMAIL PROTECTED] SIP/2.0
Message Header
Via: SIP/2.0/UDP 192.168.1.57:5060;branch=z9hG4bK03865702;rport

How do other UA's handle such a situation. I'm currently responding with
481.
TIA,
Jack
