APAR status
Closed as program error.
Error description
There are many situations where an UA can switch between transport type [from UDP to TCP]. If this type of Session Initiation Protocol (SIP) message passes through the container then the container fails to deliver it back to SIP Proxy. At the end, the message does not reach the expected destination.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V6.1 and V7.0 * **************************************************************** * PROBLEM DESCRIPTION: Cancel for a long Invite message is * * not received by the proxy for UDP * * messages * **************************************************************** * RECOMMENDATION: * **************************************************************** The transport is changed to TCP because of the long message, the Cancel request is still being sent using UDP and therefore does not reach the proxy
Problem conclusion
The Cancel request is now being sent using TCP to the proxy server. This is done by changing the trasport parameter on the Invite custom proxy header so subsequent requests will be sent correctly. The fix for this APAR is currently targeted for inclusion in fix pack 1.0.0.5.
