                    <br>
                    I have an error that I have not yet been able to
                    solve and would like the help of colleagues to
                    indicate a correct path.<br>
                    The problem that is occurring is that when the
                    client disconnects the call kamailio is not sending
                    the BYE forward until arriving at the asterisk.<br>
                    <br>
                    Both in the test scenario and in the production
                    scenario the problem is the same and the message I
                    see in the capture is 404 Not here, msg this coming
                    from kamailio.<br>
                    <br>
                    Production scenario.<br>
                    <br>
                    PSTN <----------> Dialer --------->kamailio
                    -----------> asterisk1<br>

                                -------> asterisk2</p>
                    <br>
                    <br>
                    When this occurs, the calls that are disconnected by
                    the client are in a "zombie" state in asterisk, and
                    end up being terminated by timeout with the
                    following message in the asterisk CLI:<br>

                    several incrementing counters, as per the

                    <br>
                    If I take the kamailio from the move and point the
                    sipp to only one of the asterisk, the
                    retransmissions do not happen and BYE follows
                    normally.
