OCS Front End Validation Failed RRS feed

  • Question

  • Hi All,
    I have deployed OCS 2007 SE edition with one Edge server and whenever I run the Validation tool on Front End or Edge Server, I got following error:

    Attempting to establish SIP dialog from user1@domain.com to user2@domain.com using ocs.domain.com   Maximum hops: 3
    Received a failure SIP response: User sip:user2@domain.com @ Server ocs.domain.com
    Received a failure SIP response: [
    SIP/2.0 500 The server encountered an unexpected internal error
    FROM: "User1"<sip:user1@domain.com>;tag=45ea582e5deea28f776f;epid=epid01

    ]

    Suggested Resolution: Use the maximum hop count to determine the server that generated this error. For example, if the maximum hop value is 2, then it is likely that this error was generated by a server that is 1 (immediate target) or 2 hops away. Check whether the target user is a valid user and that the target user domain is trusted by the source user's pool. Check the connectivity between the source and target pools.

    Very very thanks in advance for any help.

  • Do you have the certificate configured on the OCS Server?

  • Yes,
    I have configured Windows CA certificates on OCS Front End and Edge  Server internal interface. I have also configured comodo certificates on Access Edge and Web Conferencing public interface.

    Communicator is working find from internal as well as external and people able to do 1-1 and Conf. This error is coming on Front End as well as Edge validation tool.

    Thanks

    Unless this was a mistake in the post, if you are using a lab with the actual name of domain.com then you might have a typo somewhere in your OCS configuration.

  • Sorry Jeff,
    This was a typo in the post. Actual domain name is some thing else.
