Problem summary
**************************************************************** * USERS AFFECTED: All IBM WebSphere Application Server * * Feature Pack for Communications Enabled * * Applications (CEA) Session Initiation * * Protocol (SIP) Container users * **************************************************************** * PROBLEM DESCRIPTION: Sysroute of: PM59224 * * A redundant Record-Route header is * * added to the SIP messages. * **************************************************************** * RECOMMENDATION: * **************************************************************** 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.
