“On the 19th of December Office Communications Server 2007 R2 was Released To Manufacturing (Build 6907), so it is in good time for the official launch on February 3rd.

New in this version are a lot of things like telephony enhancements and new clients including the Attendant Console (A group based switchboard solution) an updated "Office Communicator for Windows Mobility R2" (Nicknamed CoMo) that includes phone state on mobile phone calls and One Number features (I will do a review of this client later), Dial-in conferencing support (Including CWA support for external clients) and of course enhancements to the overall architecture (Including a move to a 64 bit Server platform) and not least an updated CWA that now supports Desktop Sharing also for external users and non-Microsoft browsers ... and much, much more that I will talk about later (Or that you can find at other blogs).”
