Hello, To my understanding the rport parameter of the Via header is irrelevant when a request is sent over TCP transport. PJSIP is putting the parameter into the header, regardless of the transport used. This is actually allowed but we have just run into a SIP client that crashes when it receives a SIP request over TCP with the rport parameter present in the Via header. Unfortunately it is pretty difficult to get a fix from the client vendor so I am wondering if it would be possible to change the PJSIP logic to insert the rport parameter only when UDP transport is used.
