CM4.1 and Exchange 2k7.... Trixbox/Asterisk?

Unanswered Question
Jul 17th, 2007

I would like to connect Exchange 2k7 with CM4.1. Microsoft doesn't support it in a production environment. My question is, what solution can I use as maybe a VOIP gateway between Exchange and CM4.1 to allow this to work? I have seen implementations of Asterisk but it only uses SIP over UDP and Exchange uses SIP over TCP. Others have stated OpenSER "Sip Express Router" works. Upgrading to CCM 5.0 is not an option at the moment.

What should I use as a solution to bridge CCM 4.1 with Exchange 2k7 and is anyone using this solution in production?

I have this problem too.

Could you please tell me, what exactly you wanted to achieve by integrating CCM 4.1 & Exchange 2k7 ?

I would like to use Exchange as my VM provider instead of Unity. I am not prepared to upgrade CCM to v5.

I am looking for a low cost solution that could treat CCM 4.1.x as a legacy pbx and connect it to a SIP gateway which will properly connect to Exchange...
