[Asterisk-Users] MWI indicator HINT on Snom thru IAX?

[Colin Anderson]

I have many remote locations that dial into a central server to retrieve
voicemail via IAX. Outbound calls are handled as SIP calls from a Snom to a
local (to them) Asterisk server that dials the main server thru IAX. I have
trained them to check their voicemail via the emailed WAV file, however some
of them are, how shall I put it, idiots*, and insist that they *have* to
have the MWI indicator light on their phone and / or a stutter tone to
indicate the presence of voicemail. Is there a way to propigate MWI hints
through IAX? I have read snippets in the list archives that indicate some
people are working on it, but other than that I haven't seen anything. Has
anyone done this, or is there a way I could fake it? tia

*Actually, it's largely unfair to say this. This is regular expected
behavior, it just frustrates me that they are unable to forget the old way
of doing things.
