Hi,
I’m running asterisk 11.17.1 , and build my own custom voice mail.
What is the option to send notify on a new message waiting (MWI)?
Thank,
Noam

You can do it in AMI, I’ve had mixed results doing it with AMI as some of my phones will accept the notice and some will not.

Action: SIPnotify
ActionID: 2
Channel: 701
Variable: Event=message-summary,Content-Type=application/simple-message-summary,Content=Messages-Waiting: yes,Content=Voice-Message:1/1

Or you could manipulate the spool directory and let asterisk send the notify itself.

Asterisk 11 doesn’t really have a good mechanism for doing this. As mentioned you can try to craft the NOTIFY yourself or coerce app_voicemail into doing it as a result of manipulation.

In 13 and above there’s an external MWI module for exactly this purpose. It replaces app_voicemail and allows external manipulation of MWI, one such method being through AMI[1] or if you prefer through the Asterisk REST interface[2].
