OCS IM Multiparty Error RRS feed

  • Question


    Hi all,


    i have a strange problem when i am trying to make a multiparty IM Session.

    I have a mixed environment with one LCS and one OCS server, but i don't know if this matters in this case.

    All the users which i try to invite to the multiparty IM session are on the ocs pool.


    I can also communicate with each of this users seperate in a peer to peer session.

    But i try to invite a third user i get the error 504 in ocs client.

    In the application event log i get:


    A SIP request made by Communicator failed in an unexpected manner (status code 80ef01f8). More information is contained in the following technical data:
    RequestUri:   sip:First.Last@domain.at;gruu;opaque=app:conf:chat:id:40AC85885D8B0B4EADEDCCCEEA24F8FA

    Thank you for helping

    Kind regards

  • Problem was with frond end OCS 2007 server IM conferencing IP address option. The Server has two IP Addresses, because in a mixed environment with LCS 2005, the Pool Name and the Hostname from OCS Server can not be resolvable to the same ip address. As soon as i but the IM conferncing option to listen an ALL ip addresses (Port 5062) the error gone away.
