Hello, rport in top Via of the incoming request indicates that the sender whats received parameter in the response. If not, it should not be added.
However, if source ip is different that the Via IP of the incoming request and you use force_rport() in kamailio.cfg, then kamailio should add the received parameter even rport is not in the incoming Via.
