You can kind of kludge this right now. Creating an empty file called
msg0000.txt in a voicemail mailbox directory will trigger MWI for the
extension(s) associated with that mailbox. Removing the file clears the
indication. I've played with this on Zap channels and it works a treat. (The
reason for playing was to see if we could get MWI to signal presence of
messages in an external voicemail system).

I've thought about voicemail through AGI too - I guess cos I can't code C to
save my life but can get by in Perl. It's semi reinventing the wheel, but I
have to say that I'd prefer to see the voicemail backend be stored in a
database - it opens up all sorts of other possibilities and gets around the
current problems of message numbers getting out of sequence etc.
