Re: [Users] Asterisk OpenSER and Exchange 2007 Unified Messaging

Greetings list, I'm in the process of configuring Asterisk <-> OpenSER <-> Microsoft Exchange 2007 Unified Messaging. I have a windows based proxy that works great, and want to accomplish the same feat using OpenSER. Below are network captures from the working proxy and OpenSER. From comparing the working call and the OpenSER call it looks like OpenSER needs to modify the CONTACT header in its last "OK" response. I'm not sure that's right, but more importantly I'm not sure how to do this in the config. Any help or direction is greatly appreciated. Thanks, -jon p.s. Please cc me on any replies, I'm not currently subscribed to the list. openSER unsuccessfull call negotiation =========== # U +9.215930 asterisk:5060 -> openser:5060 INVITE sip:8885555@openser SIP/2.0.
