Open source PBX vs. conventional PBX
My recent how-to article on Trixbox with Exchange UM integration has generated quite a large amount of interest and from what it seems a large part of the IT community is looking/interested in Unified Messaging (this is suggested by keyword searches from...

·         PSTN breakout with an analogue terminal adaptor – 0% complete

·         Finally an OCS 2007 R2 integration with Trixbox 2.8 – 0% complete
