Problem summary

• ****************************************************************
  * USERS AFFECTED: All IBM WebSphere Application Server version *
  *                 6.1 users of the Session Initiation Protocol *
  *                 (SIP) Proxy who enable the overload feature. *
  ****************************************************************
  * PROBLEM DESCRIPTION: We need to make our "overload  SIP      *
  *                      response" configurable                  *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  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.
