I also am taking your advice on pursing another SIP proxy to implement this. -John

Is it possible to route SIP NOTIFY messages through * ?
Basically, I have an external VoiceMail application that needs the ability to send SIP NOTIFY messages to * users, in order to do MWI to the SIP phones. I realize the asterisk voicemail application does this, but does * have the ability to accept these SIP messages from another application. If so, will my application have to REGISTER then INVITE the phone then send the NOTIFY message?
Currently, my application can send NOTIFY messages directly to the phones in order to turn on and off MWI, but I would really like to be able to send these messages to * and have it handle the routing to the endpoints as * knows all the endpoints due to registration and proxy capabilities. Any input on if and how this can be done would be appreciated.
Incoming NOTIFYs are not handled by Asterisk at all. Asterisk sends outbound NOTIFY messages for MWI to SIP peers with mailbox= definition in [peer] section of sip.conf.
The problem with routing incoming NOTIFY is how to handle them, as with many other SIP non-call things in Asterisk, Is the user part of the URI an extension or a SIP peer? It's not obvious. We can't easily have two name spaces, so today the default handling is sending a NOTIFY to an extension. SUBSCRIBEs have more or less the same problem, the implementation today allows SUBSCRIBE to an Asterisk extension. Many Asterisk admins want to subscribe to a SIP peer, which breaks the architecture somewhat.
The best solution today is to use a SIP proxy for doing this kind of stuff.
