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.<br>

Re: [Asterisk-Users] unsolicited NOTIFY messages from Asterisk</div>
<div><br>
</div>
<div>can you give a little more detail here?</div>
<div> </div>
<div>I assume * is sending the SIP messages. Where is is sending
them. To the ITSP or the PHONE?</div>
<div>What does the SIP message contain? Is is MWI? is it 'OPTIONS'
keepalive?</div>
<div> </div>
<div>Try posting a Sip Debug output from * that contains the
dialogue in question</div>
<div> </div>

hi,<br>
i am getting unsolicited NOTIFY messages from Asterisk after the<br>
subscription.<br>
Is this type of NOTIFY messages is supported in any of the RFCs..? <br>
<br>
Because, the SIP stack with 3265 compliance, does not support any such<br>
NOTIFY messages and discarding those.<br>
I need the justification for this kind of NOTIFY messages sent by
Asterisk.<br>
<br>
I need your valuable inputs... <br>
<br>
Thanks in Advance,<br>
Subashini<br>
