I think I can give a slightly longer reply now, but the answer is still SMDI (Station Messaging Desk Interface)
You have identified one of the challenges of interfacing with a proprietary PBX, namely: how do I know where the call was redirected from? The other trick is turning on message waiting lamps. This is what SMDI was invented for, and Asterisk only just recently has been provided with an SMDI interface (it was a bounty for several years - somebody finally wrote something late last year, and if you check it out in the bug tracker you'll see that there's a fair amount of positive interest in it). Your PBX needs to support SMDI, and if it does not (can you say Nortel?), you'll need a gateway of some sort such as Intel's PIMG or CTLs PBXLink. I do not think anyone has actually integrated an Asterisk with SMDI yet, so this is not for the faint of heart. Give us six months (<shameless plug>or give us a call and we'll help you make it happen</plug>). John Todd and I have been chatting about this a fair bit recently; this is really exciting for the legacy telecom folks among us. If you want to be on the bloody-edge, this is the ticket! SMDI support in Asterisk is positioned to be a killer app, because a lot of old voicemail systems are showing signs of impending death, and folks are loath to buy in to another round of proprietary hell.
