Paul I don't know why you are overcomplicating things. Just like
asterisk can do the MWI for FXS it should be able to pick up the MWI
form the Telco on an FXO, and then based on that asterisk should be
able to turn on the MWI on any ohter device within asterisk. It would
work something like this:
/etc/asterisk/zapta.conf:
detecttelcovoicemail=Sip/101,Zap/5

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.
