APAR status

• Closed as program error.

Error description

• The problem is that a 480 Temporarily Unavailable response is
  not sent upstream by the Session Initiation Protocol (SIP)
  Container. The scenario is:
  UAC is calling an UAS through the SIP Proxy. SIP Proxy forwards
  the initial INVITE to the UAS. UAS responds with a 100 Trying
  response, then with a 180 Ringing response. After that UAS
  rejects the call with a 480 response. SIP proxy does not send
  this response to the UAC. The log file shows the following:

Problem conclusion

• A specific SIP object was invalidated prematurely. This issue
  was fixed and now the SIP container is postponing it to a later
  phase.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 6.1.0.23  Please refer to the Recommended Updates
