Hi
I wanted to send MWI message from asterisk to old PBX,and use Asterisk as voicemail box… the old pbx does not support SIP.
so it looks like these
Asterisk—sip trunk–Cisco2821—QSig—PBX–End points
I thought of two options, first I have media gateway, CISCO 2821 router in-between the PBX and the asterisk BOX, voicemail calls are sent from PBX to asterisk box which is the voicemail bank for pbx users…the problem is sending MWI notication to PBX end points
SIP MWI notify is sent to Cisco gateway, which is translated to QSIG, I had it working, but now facility info is missing? and before could get mwi activate/deactivate(80,81) message, but now the facility info is missing…
this is isdn debug output on the gateway for the MWI notification…

The second option i thought about was to connect PBX directly to Asterisk using diguim E1 cards.
