[Asterisk-Users] unsolicited NOTIFY messages from Asterisk

[Chris A. Icide]

Note however, that in the unsolicited NOTIFY that Asterisk sends for 
MWI, it includes a ;tag= as part of the NOTIFY.  This will break some 
devices as they will not accept the NOTIFY because the tag doesn't match 
any transaction that is open.  The correct way to send an unsolicited 
NOTIFY would be without the tag altogether.
