Problem summary

****************************************************************
* USERS AFFECTED:  Websphere Application Server Session        *
*                  Initiation Protocol (SIP) Container users.  *
****************************************************************
* PROBLEM DESCRIPTION: A redundant Record-Route header is      *
*                      added to the SIP messages.              *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The SIP Container a 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 an 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 the 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 8.0.0.3.  Please refer to the Recommended Updates
