    <tt>Hi Schneur,<br>
      <br>
      Yes, you were, still the right approach, as Alex mentioned, is to
      report and have the bug fixed in the device.<br>

                <br>
                Well, there is a reasonable way to fix it on your side -
                use the dialog module (have dialog state) and for
                sequential requests (like the ACK in question) use the
                validate_dialog() - <a moz-do-not-send="true"

                - to find out the broken RURI/Routes/Contact and have
                them fixed via fix_route_dialog() function - <a
