In the new bis, it is mandatory that UA should support TCP transport. Assume a UA with a TCP connection 1 sending to the proxy, and a TCP connection 2 for receiving from the proxy. Now assume that the TCP connection 1 and 2 have gone down/timed out. This may due to a temporary failure. The proxy recovers asap and sets up a new TCP connection for sending to the UA. It may set up the new connection to the UA before the TCP time out found on the UA. What should the UA do? Should the UA try to set up a connection to the proxy so that requests can be sent/resent? Or the UA would just release all the calls it has with the proxy and try for another proxy if available?
