You're right- that is a simplified way of putting it (a subdialect, as it
were). Point is, to my knowledge (I'll happily stand down if it is) that
support isn't presently there, and there hasn't been a huge rush of
people
looking for it. It's really only useful in the extremely small office
(SOHO) situation, or to someone who wants to integrate a non-asterisk VM
system with Asterisk- the converse of what most people here generally want
to do. (I'd have to wonder why you'd do that, since Asterisk VM works
so
well, and is easily customized to your needs). I do have customers who
might see some advantage to it- but more in a unified messaging sort of way,
so that they could 'collect' all their voicemail, answering machines,
etc,
into one storage location (asterisk) and use that to transport it out
again. Plus, as someone else pointed out- it might not be stutter tone-
there are a few different ways of signalling voicemail on analog lines. All
of which should be possible to handle in Zaptel drivers- but more research
would have to be done.
