Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM Websphere Application Server version 8  *
    *                  Session Initiation Protocol (SIP) users     *
    ****************************************************************
    * PROBLEM DESCRIPTION: A response on PRACK after a reproxied   *
    *                      INVITE, can cause an inappropriate      *
    *                      invalidation of the session.            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When the response on the PRACK was processed by
    TransactionUserWrapper.completeTransactionForOriginalRequest(),
    the transaction was completed and session was invalidated.
    

Problem conclusion

  • Passed the request method to
    TransactionUserWrapper.completeTransactionForOriginalRequest(),
    and now we don't invalidate the session if it's different from
    the method of the original request.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.0.0.4 and 8.5.0.1.  Please refer to the Recommended
