    Users want to control the error response during an
    overload situation
    

Problem conclusion

  • The SIP proxy can be configured to detect overload situations.
    When the proxy is configured for "overload protection", it
    monitors the amount of traffic processed at the proxy and
    limits the number of new requests.  If overload occurs, it
    rejects some SIP requests with an error response.   By
    default, the proxy responds with a "503 Service Unavailable"
    response.
    
    Some customers prefer to use a different error response.   So,
    we made the response configurable.  In the administrative
    console, you can set the overload "status code" and "reason
    phrase" via custom properties.
    
    These properties can be added to the SIP Proxy custom property
    settings to change the response:
    overloadResponseCode    (by default,  503)
    overloadResponseReasonPhrase    (by default,  "Service
    Unavailable").
    
    The fix for this APAR is currently targeted for inclusion in
    release 6.1.0.13.
