"No question there is a lot of buzz around Microsoft Lync. Planned interoperability between Cisco TelePresence endpoints and Microsoft Lync is targeted for delivery in the first half of calendar year 2011. The solution will consist of the same components and work the same way that Cisco TelePresence Video Communication Server (VCS) and Cisco TelePresence Advanced Media Gateway work with Microsoft OCS 2007 R2 today. VCS will connect to the Lync server via a SIP trunk and enable CIF video interoperability in addition to the other capabilities provide by the integration such as presence, encryption, etc. The Advanced Media Gateway will bring the added benefit of HD (720p) or VGA resolution and enable the best visual experience possible between the two environments.
