For Mediation Server, modifying the topology exported from the Planning Tool into Topology Builder requires three updates: 1) setting the Mediation pool fully qualified domain name (FQDN), 2) selecting a default public switched telephone network (PSTN) gateway for the Mediation Pool, and 3) updating the FQDN for each server in the pool.

To edit Mediation pool properties
  1. Start Topology Builder: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Topology Builder.

  2. From Topology Builder and with the Redmond.tbxml open from the previous procedure, expand the Redmond node, and then expand the Mediation pools node.

  3. Right-click Mediation Pool, and then click Edit Properties.

  4. Enter the FQDN of the Mediation pool.

  5. Next, scroll down to the list of gateways associated with the Mediation Server. From the list, click one gateway, and then click Make Default. A green checked symbol should appear next to the gateway chosen.
