  * RECOMMENDATION:                                              *
  ****************************************************************
  When handling PRACK response (after invite), the container
  ignored the response method (PRACK) and handled the response
  as ACK response which means that the invite was confirmed and
  cancel can not be sent.
  

Problem conclusion

• In this fix we verify that the response is ACK response and in
  this case we set the invite as confirmed.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.1 for the Feature Pack for Communications
  Enabled Applications.  Please refer to the Recommended Updates
