When you want to send requests using TCP, you need to tell PJSIP that the request is to be sent with TCP, and this is done by adding ";transport=tcp" parameter either in the target URI or by adding a route set that uses TCP (the --proxy or --outbound option in pjsua, e.g. --proxy "sip:theproxy;lr;transport=tcp"). > Also, I have another related question.

When you register to the server with TCP, pjsip will keep the socket open and server can send inbound requests using this connection.
