"SIP/2.0 408 Request Timeout" error message is incorrectly logged on a Mediation server in a Lync 2010 environment

View products that this article applies to.


Assume that an OperationTimeoutException exception occurs on a PSTN gateway in a Lync Server 2010 environment. This environment has a Mediation server and a PSTN gateway deployed. In this situation, a SIP/2.0 408 Request Timeout error message is logged on the Mediation server. Therefore, the Outbound Routing application on Lync Server 2010 does not try to route the call.

Note A 504 Gateway Timeout error message should be logged on the Mediation server instead.
