APAR status

  • Closed as program error.

Error description

  • WebSphere Application Server Session Initiation Protocol (SIP)
    Proxy
    -
    
    The remote SIP server is creating a connection to the SIP proxy.
    The message sent to the SIP Proxy is in error.  As a result,
    the SIP Proxy does not update the routing table properly. Any
    subsequent messages over this connection will not work
    properly. This forces the SIP Proxy to open a new connection to
    the remote SIP Server.
    

Local fix

  • To fix this problem:
    
    1) The originator of the NEGOTIATE message can change the
      Max-Forwards header so that it is greater than 0.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server V6.1 and   *
    *                  V7.0 users of Session Initiation Protocol   *
    *                  (SIP) Proxy                                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: The SIP Proxy is not updating its       *
    *                      routing table properly when a new       *
    *                      request is received which has a NAT     *
    *                      address.                                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The SIP Proxy is not updating its routing table properly when
    a new request is received which has a NAT address.   This only
    occurs when the proxy responds to the request with an error
    (TCP and TLS only).
    

Problem conclusion

  • Changed the code to update the routing table with the NAT
    address even when the SIP request is in error.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 6.1.0.35 and 7.0.0.15.  Please refer to the
