Mediation Server Bypass

Topic Last Modified: 2010-09-24

In Microsoft Lync Server 2010, we recommend that you configure voice traffic to bypass the Mediation Server when possible. Doing so helps improve call quality by optimizing the media path, reducing latency, minimizing unnecessary transcoding, limiting packet loss, and eliminating potential points of failure.

Mediation Server bypass also provides you bandwidth savings in configurations where a Mediation Server and a PSTN gateway or PBX are at different sites connected by WAN links, especially if bandwidth over the link is limited. Offloading the media processing from the Mediation Server also improves scalability.
