OCS Outbound Routing RRS feed

  • Question

  • Hi guys,

    I building OCS 2007 R2 SE and Mediation , both running 2008 R2. My Mediation server use single NIC.

    I want to integrate with Call Manager. I've already configured all the necessary configuration. So when I try to call from OCS to Outbound, I've got this error at my OCS SE :

    An attempt to route to a gateway failed.

    Could not route to gateway mediation.mydomain.com:5061, the attempt failed with response code: Timeout.

     

    At first I suspect the antivirus because I can't telnet port 5061 from SE to Mediation, so I uninstall the AV, now it can telnet. But I can't still do outgoing call, the error still showing at the event viewer.

    What could probably wrong ?

    I can telnet SE to Mediation using port 5061. I can telnet to CUCM using port 5060 too.

     

    How can I troubleshoot the flow for Outgoing call ?

     

    And then when from Cisco client want to call to extension OCS it cannot too. How I troubleshoot from CUCM area and OCS whether OCS already receiving packet from CUCM ?

  • Do a new debugging session on the Mediation server and select SIP & S4 and view the output with snooper tool from Resource Kit

  • Have you tried going to port 5060 (using TCP)?
