Define a SIP/CSTA Gateway IP Address
Topic Last Modified: 2011-02-01
If Lync Server will connect to the SIP/CSTA gateway that you deployed for remote call control using a Transmission Control Protocol (TCP) connection, then you must define the IP address of the gateway in Topology Builder. This step is not necessary for gateways that support Transport Layer Security (TLS) connections. You can skip this procedure and continue deployment of remote call control by following the steps in Enable Lync Users for Remote Call Control.
To define the SIP/CSTA gateway IP address 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.
Choose the option to download an existing topology.
Expand the Trusted application servers node.
Right-click the trusted application pool that you created as described in Configure a Trusted Application Entry for Remote Call Control, and then click Edit Properties.
Clear the Enable replication of configuration data to this pool check box.
Click Limit service usage to selected IP addresses. The default setting is Use all configured IP addresses.
In the Primary IP address text box, enter the IP address of the SIP/CSTA gateway.
To update the topology in the Central Management store, in the console tree, click Lync Server 2010 and, from the Actions pane, click Publish.
