Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of WebSphere Application Server    *
  *                 V7.0                                         *

  ****************************************************************
  * PROBLEM DESCRIPTION: The Session Initiation Protocol (SIP)   *
  *                      router was incorrectly comparing the    *
  *                      server types upon start up.             *
  *                                                              *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The SIP router was not looking for the correct server type
  name and thought it should have started the inbound channel
  chains.
  

Problem conclusion

• The SIP router now correctly looks for the correct server type
  name for the Deployment Manager and Node Agent and does not
  try to start any inbound channel chain groups.
