 Hello.

force_rport() does not work on BYE for locally generated 200 OK.

route {
....
    force_rport();
    b2b_server_new("caller");
    b2b_client_new("callee", "sip:user at host");
....
}

200 OK's Via received= correct and used, but only IP, rport missing.
When client add empty rport in BYE - reply is ok.

There are workaround to get 200 OK on nated client for BYE?)
