SIP 503 / MSDiagnostics error 12000 - Lync 2010 Mediation Server issues with SIP trunking RRS feed

  • Question

  • Dear all,

    We have OCS R2 + Lync running fine in coexistence mode with one issue alone: the mediation server does not want to route the PSTN gateway.

    Although the Mediation Server checks out fine, it doesn't seem to get referenced by the error log at all.

    Here's the log detail we get when doing a dialout:

     

    A SIP request made by Communicator failed in an unexpected manner (status code 80ef01f7). More information is contained in the following technical data:

  • This turned out to be some routing issues on the PSTN NIC of the Mediation Server. Outbound calls work fine now.

    I just have two things left to do here:

     

    1. Get Inbound calls working (I don't seem to find the Lync equivalent of the Mediation Server Location Profile and I need to modify the incoming CLIs).

    2. Get the correct CLID on outbound calls (at the moment it's picking a random number out of our list of DDIs).

    Any insight on this is very welcome :)
