Sip Notify / MWI Format & Content
 

Hi Martin

There is a really cool new SIP client for the Iphone called Siphon (see siphon - Google Code) and I have been talking to the developer about possibly adding support for MWI.

I thought I would help by getting him some more details on what type of Sip Notify message (format & content) his client would need to recognize in order to support MWI.

Can you tell me (us) what message is sent by Voxalot (format & content) when a new Voice Mail message is received? Any other useful information would also be appreciated.

Thanks

Richard

I don't speak for Martin, but the MWI protocol is detailed in RFC-3842. The SIP messages can be easily monitored using a packet monitoring program such as Wireshark.

When a message arrives Voxalot sends a sip notify message with body as follows:
Messages-Waiting: yes
Message-Account: sip:*500@voxalot.com
Voice-Message: 1/0

The SIP phone will reply with the usual "SIP/2.0 200 OK".

Thanks Boatman, I past your feedback along.
