Problem conclusion

• A fix was made in the SIP Container so a Via header field in
  ACK requests is set according to the preferred outbound
  interface setting.
  
  The following SIP Container custom property should be applied
  to activate the fix:
  
  Name: enable.set.outbound.interface
  Value: true
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.17 and 9.0.5.2.  Please refer to the Recommended
