How to get Asterisk working with Exchange 2007
I’d alluded before about my dabbling with Asterisk as an open source SIP PBX and how I hadn’t mustered the energy to try and get Exchange 2007 which uses SIP over TCP to talk to Asterisk which uses SIP over UDP. at the time I was considering a patch, well with one thing and another I still haven’t got round to it but I do get a emails asking about it and I recently was directed to a very useful post by Ryan an antipodean IT pro who’s reluctantly dipping his data toe in the voice water. I came across Ryan’s post through Dennis over at MSGoodies.
The key is to use sipX which
happily eventually acts as an intermediary with SIP over both UDP and TCP in it’s lexicon. Ryan gives an excellent account of setting the whole infrastructure up within VMware so you can familiarise yourself with some of those novel VoIP protocols
maybe, just maybe, I’ll get round to trying it soon
