An update is available that improves the efficiency of PSTN call routing in Lync Server 2010


View products that this article applies to.

Symptoms

This article describes an update that adds 10-second timers to Microsoft Lync Server 2010 Outbound Routing (OBR) components. The timers are used to improve efficiency when the OBR components route Public Switched Telephone Network (PSTN) calls. The timers start when the OBR components send INVITE requests to PSTN calls. If the OBR components do not receive a PSTN gateway response within 10 seconds, the OBR components route the calls to other PSTN gateways.
