I have been recently tasked with resolving a number of Lync SCOM Errors we have been receiving since rolling out Lync 2013 Management Packs. If you don’t configure the alerts in the Management Pack you will be sure to see a number of issues which could potential be ignored, changed or disable completely.

Chapter 4. Causes
MEDIATIONSERVER_GATEWAY_OPTIONS_FAILED (Event ID: 25051) was recorded 5 times. Check other MOM alerts for more details. The MEDIATIONSERVER_GATEWAY_IP_NOT_AVAILABLE (Event ID: 25036), MEDIATIONSERVER_GATEWAY_TLS_NEGOTIATION_FAILED (Event ID: 25040) are examples of events that signal connectivity error conditions with the Trunk peer.
Chapter 5. Resolutions
If the failure is MEDIATIONSERVER_GATEWAY_IP_NOT_AVAILABLE (Event ID: 25036), make sure that the correct listening IP and port for the Trunk have been configured in the PSTN Trunk object in management store and that the Trunk is up and running and able to accept incoming connections from the Mediation Server.
If the failure is MEDIATIONSERVER_GATEWAY_TLS_NEGOTIATION_FAILED (Event ID: 25040), make sure that both the Mediation Server and the Trunk are configured for TLS and that the CA for the Trunk’s certificate is the trusted certificate path on the Mediation Server and the CA for the Mediation Server’s certificate is in the trusted certificate path on the Trunk.
