500 Internal Server Error RRS feed

  • Question

  •  We are running

    OCS -- OCS Mediation Server -- Dialogic Media Gateway 300 -- BRI ISDN

    Client:           alimo-pc@domain.local
    OCS:             ocs.domain.local
    Mediation:         medi.domain.local

    Everything is configured and ready to go
    Outbound Calls go through all the way from the Communicator but rejects at the Dialogic end.
    While sniffing Packets at the Dialogic side all UDP SIP/RTP Packets are received at port: 0
    Which doesnt make sense as it should be received in media streaming range 60000/64000 which is configured from both ends Mediation and Dialogic.

    Below is the event log from the Communicator Client.

  •  It was the windows firewall on Dialogic side and it worked perfectly and all calls went through just by adding an exception to the port 5060 in the windows firewall.
