Configure Mediation Server (Office Communications Server 2007 Migration)
Topic Last Modified: 2012-10-17
This procedure describes the steps to configure the Microsoft Lync Server 2010 pool to use the Lync Server 2010 Mediation Server instead of the legacy Microsoft Office Communications Server 2007 Mediation Server.
Important
Before running the procedure that follows, ensure that your public switched telephone network (PSTN) gateway is certified to work with Lync Server 2010 Mediation Server. Additionally, ensure that gateway is updated to the latest firmware version. Consult your PSTN gateway manufacturer for additional information.
To successfully publish, enable, or disable a topology when adding or removing a server role, you should be logged on as a user who is a member of the RTCUniversalServerAdmins and Domain Admins groups. It is also possible to delegate the proper administrator rights and permissions for adding server roles. For details, see Delegate Setup Permissions in the Deployment documentation. For other configuration changes, only membership in the RTCUniversalServerAdmins group is required.
Note
For details about finding qualified PSTN gateways, IP private branch exchanges (IP-PBXs), and SIP trunking services that work with Lync Server 2010, see "Microsoft Unified Communications Open Interoperability Program" at https://go.microsoft.com/fwlink/p/?LinkId=206015.
Configure Mediation Server by Using Topology Builder
Log on to the computer where Topology Builder is installed as a member of the Domain Admins group and the RTCUniversalServerAdmins group.
Start Topology Builder: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Topology Builder.
Select Download topology from existing deployment, and then click OK.
In the Save Topology As dialog box, select the Topology Builder file you want to use, and then click Save.
In the left pane, navigate to PSTN gateways.
Right-click PSTN gateways, and then click New IP/PSTN Gateway.
Complete the Define New IP/PSTN Gateway page with the following information:
Enter the gateway fully qualified domain name (FQDN) or IP address. The FQDN of the gateway is required if the gateway uses the Transport Layer Security (TLS) protocol.
Accept the default value of the Listening port for IP/PSTN gateway or enter the new listening port if it was modified.
Set the Sip Transport Protocol.
In the left pane, navigate to the Enterprise Edition Front End pool or the Standard Edition Server.
Right-click the pool, and then click Edit Properties.
Under Mediation Server, set the Listening ports.
Next, associate the newly created PSTN gateway by selecting it, and then clicking Add.
Associate the PSTN gateway to the Lync Server 2010 Mediation Server by selecting it, and then clicking Make Default.
In Topology Builder, select the top-most node Lync Server 2010.
From the Actions pane, click Publish Topology, and then click Next.
When the Publishing wizard completes, click Finish.
