  The Sip Container employes Double Record Route mechanism that
  is described in RFC 5658, it is used to deal with multi-homed
  proxies by adding 2 Record-Route headers, one for each network
  interface. In our case the problem occurs when incoming
  message is considered to use multi-home when it actually
  doesn't need to use this mechanism. The problem occured
  because the messages were sent with "sips" secured scheme that
  doesn't include transport parameter, this caused the container
  to believe that it received the message over TCP but needs to
  send the message via the default UDP transport. Thus the
  container chose to employ the Double-Record Route mechanism
  without need.
  

Problem conclusion

• When outgoing transport is evaluated we included a code path
  that checks for "sips" secured scheme and evaluates it's
  tranport to TCP.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.13. Please refer to the Recommended Updates page
