Problem summary

  • ****************************************************************
    * USERS AFFECTED:  SIP (Session Initiation Protocol) users     *
    *                  of IBM WebSphere Application Server         *
    ****************************************************************
    * PROBLEM DESCRIPTION: The application server receives an ACK  *
    *                      message from the network, but does      *
    *                      not pass it up to the application.      *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The problem occurs in a call flow that includes INVITE dialog
    creation, followed by an unsuccessful INVITE within that
    dialog, followed by successful INVITE. For example:
    
    Application Server                   User Agent
            |                                 |
            |------------ INVITE ------------>|
            |<----------- 200 OK -------------|
            |------------- ACK -------------->|
            |                                 |
            |------------ INVITE ------------>|
            |<------- 400 Bad Request --------|
            |------------- ACK -------------->|
            |                                 |
            |<----------- INVITE -------------|
            |------------ 200 OK ------------>|
            |<------------ ACK ---------------|
            |                                 |
    
    The ACK message, that is sent to the application server, is
    not passed up to the application.
