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
