Can anyone advise me on how to get the Message Waiting Indicator in Asterisk to notify phones that voice mail is waiting?
I'm posting to this mail list because I'm using ser as my SIP proxy and Asterisk as a voice mail server. I'm not using any other Asterisk functionality other than voice mail.
I assume that asterisk would have to send the SIP NOTIFY message to the registered SIP clients via ser. So will I have to create a custom Asterisk and ser modules to get this to work?
Regards, Paul

I just looked this up today for someone else. You configure the phone or the registrar in Asterisk's sip.conf file:
[cisco-Jamey.Hicks] type=peer username=jamey.hicks host=10.11.0.193 ; SIP registrar mailbox=7922 ; Mailbox for message waiting indicator
Asterisk is sending a notify to my AOR with these headers:
Event: message-summary Content-Type: application/simple-message-summary
and an example notify body:
Message-Waiting: no Voicemail: 0/12

Asterisk sends NOTIFY only to UACs that are registered at the Asterisk. If you just forward voicemail calls to Asterisk and the UACs are registered at SER, you have to use the 'externnotify'-option in voicemail.conf of Asterisk. We use a script wrapped around sipsak to turn on/off MWI by sending proper NOTIFY messages.
Hi Andreas!
Do you send NOTIFYs to all clients or only to clients which SUBSCRIBE for MWI?
