In order to use the Mediation Server that is used by Microsoft Office Communications Server 2007, you must configure Lync Server 2010 to use this server.

If a Voice Route and Voice Policy existed in the legacy pool, after you merge Office Communications Server 2007 with Lync Server 2010 and run the Import-CsLegacyConfiguration cmdlet, the Lync Server 2010 pilot pool now has all the necessary configuration information to do the following:


To enable the Lync Server 2010 pilot pool to use the legacy Mediation Server, you must have a Voice Route and Voice policy configured that point to the legacy Mediation Server. If you do not have a legacy Voice Route or Voice Policy, complete the following steps to configure these settings by using Lync Server 2010 Control Panel or the Lync Server Management Shell.
