I have a remote user, registered to a Asterisk box that is local to them on their network. We use IAX to communicate with another Asterisk box.
All of their voicemail is collected and stored on the Asterisk box that is at a second location.
In the sip.conf there is a place for mailbox=xxx@context so that the end point connected to that Asterisk box knows what voicemail to look at for message waiting indication.
Is there a way to set the sip.conf ‘mailbox=’ to point to another (remote) Asterisk box for voicemail indications?
For example: mailbox=some_asterisk_server.com/xxxx@context
Or maybe: mailbox=xxxx@iax_context
