Re: [Asterisk-Users] unsolicited NOTIFY messages from Asterisk

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.

If the SIP device is sending a SUBSCRIBE, then it is specifically asking for a NOTIFY.

The only time that Asterisk wilol send an unsolicited NOTIFY is in the case of a MWI. The reason that the unsolicited NOTIFY is sent as a voicemail notification is that the vast majority of vendors have implimented it in this way. very few devices can explicitly subscribe for a MWI, so Asterisk uses the registration of the device as an implicit request.

For us to be able to help you with your issue, you need more information that just a SIP debug.

You need to:

    1) Tell us the device you are using (is it a phone (specific model), is it a connection with an ITSP).

    2) get a debug output from the console.

    3) get a debug from the SIP DEBUG command.

Remember, the more information you give, the less obscure your problem will be to the reader, and the higher your likelyhood of receiving an answer that will be of help to you.

Subject: Re: [Asterisk-Users] unsolicited NOTIFY messages from Asterisk

can you give a little more detail here?

I assume * is sending the SIP messages. Where is is sending them. To the ITSP or the PHONE?

What does the SIP message contain? Is is MWI? is it 'OPTIONS' keepalive?

Try posting a Sip Debug output from * that contains the dialogue in question

cheers

hi,
       i am getting unsolicited NOTIFY messages from Asterisk after the
subscription.
Is this type of NOTIFY messages is supported in any of the RFCs..?

Because, the SIP stack with 3265 compliance, does not support any such
NOTIFY messages and discarding those.
I need the justification for this kind of NOTIFY messages sent by Asterisk.

I need your valuable inputs...

Thanks in Advance,
Subashini
