Mediation Server Time Out RRS feed

  • Question

  • I have a setup with a Pool and 2 Mediation Server. I have configured the Voice Configuration and tested with Route Helper. All test on the Route Helper pass but when i call from Comunicator to use the 2nd Mediation Server Route, it will fail. I have no issue with the 1st Mediation Server route.

    Below is the event id from the client.

  • Check if your Mediation Server has a correct certificate

    Must be FQDN of Mediation Server and must be trusted by your client

     

    This is the error that you receive:

    The peer actively refused the connection

     

    Might also be a firewall issue

  • Can you post a little bit more information on which certificate your use. Does the TLS nego goed right? As described earlier you probably need to update or correct your certificate (make sure the FQDN matches the name of the Mediation Server (FDQN).

     

    Wednesday, March 26, 2008 6:52 PM
  • I have checked the certificate. The FQDN matches the Certificate.

    I am checking with the security team as there might be firewall blocking the connection.

    But what ports should i request to be allowed for the connection?

  • You apparantly have problems contacting your AV EDGE Server

    Can you run validation wizards on your pool and edge servers

     

    Tuesday, April 1, 2008 11:14 AM
  • Yes, the mediation have problem connecting to the AV Edge server.

    I have removed the AV Edge on the Mediation Configuration but still have the same error on the client.

     

    I have also run validation wizards on the pool and edge. No errors shown.

     

    Will it be the log on service that is causing the problem?

    For all the OCS Servers in MY domain, the services is using MY\RTCComponentService as logon.

    For Mediation server in NCAL domain, the services is using NCAL\RTCComponentService as logon.

    Do I need to use the same logon for the services?

     

    My final solution will be reinstalling the 2nd Mediation and joined it to MY domain. Maybe this will solve the problem.

  • Did you run the validation wizard on the Mediation Server?

     

    Wednesday, April 2, 2008 4:04 PM
  • I can't find any validation wizard for the Mediation server.

    Thursday, April 3, 2008 3:33 AM
  • Run the validation wizard on the Front-End server

    You should also run the OCS Best practive analyzer

  • There was 2 A records for the Mediation server. Remove the second A records. Able to make calls after that. Thanks for the help. Smile

  • Hello all

     

    We have experienced the same kind of issue.

     

    Running Nortel IP-PBX CS1000E 5.0

    We have finished the set-up of OCS Proxy which MCM(Provided by Nortel) and FE, Mediation and AD.

    We have downloaded Validation Wizard and tried it.

    Each server says need hotfix will be needed.

    But we have already installed the latest version of hotfix.

    So, Error occured saying "already installed... diffrent version of ...."

     

    The issue is occuring in between MCM to Mediation.

     DNS record cannot be retrieved kind of error message was shown.

     

    We appreciate if anybody could let us know the resolution for this error

     

    Yoshi
