    <p>Hello,</p>
    <p>I pushed a patch to master to print a debug message when the
      socket is set on double rr. Can you retest and send again all the
      debug messages for a misrouted BYE? If the sockets is set
      correctly, then will have to look at the tcp conection lookup.</p>
    <p>Cheers,<br>
      Daniel<br>

                                              <div>My problem is with
                                                Transaction 3. In this
                                                case the BYE is
                                                originated by the
                                                callee, and Kam has to
                                                send it to the caller.
                                                As the TCP load balancer
                                                is between Kam and the
                                                UAC, Kam has to send it
                                                to the LB so then the LB
                                                can forward it back to
                                                the UAC. This works well
                                                for msgs that belong to
                                                the same transaction
                                                (INVITE, 100, 180, 183,
                                                200 OK) but it fails
                                                when they don't belong
                                                to the same transaction.</div>
                                              <div><br>
                                              </div>
                                              <div>Thanks to the newly
                                                added $tcp(c_si) and
                                                $tcp(c_sp) pseudovars, I
                                                can save the internal
                                                IP:Port of the LB, so I
                                                can send stuff later to
                                                it, my problem is that
                                                Kam doesn't seem to
                                                allow this?</div>
                                              <div><br>
                                              </div>
                                              <div>On the original
                                                INVITE, I use the
                                                following to save where
                                                I have to reach the UAC:</div>
                                              <div><br>
                                              </div>
                                              <div>add_contact_alias("$tcp(c_si)",
                                                "$tcp(c_sp)", "tls");<br>
                                              </div>
                                              <div><br>
                                              </div>
                                              <div>Then,
                                                handle_ruri_alias() will
                                                take care of setting $du
                                                to the correct (internal
                                                LB) IP:Port so I can
                                                reach the UAC, this
                                                works.</div>
                                              <div><br>
                                              </div>
                                              <div>My problem is that
                                                Kamailio doesn't
                                                identify that there is a
                                                valid existing TLS
                                                connection still up
                                                (from the INVITE), and
                                                tries to create a new
                                                one (and this obviously
                                                doesn't gives all sorts
                                                of problems).</div>
                                              <div><br>

                                                (from the example

                                                the existing connection,
                                                Kamailio tries to create
                                                a new one.</div>
                                              <div><br>
                                              </div>
                                              <div>I have a log
