    <p>That's all required not to have a dialog completed, but faild.

              <div>Scenario: invite from upstream is t_relayed to a
                client gateway. After `fr_inv_timeout` occurs, in a
                failure route I simply t_reply with "503 - Service
                unavailable", then exit(). </div>
              <div><br>
              </div>
              <div>However, the upstream provider simply ignores this
                reply, call doesn't hang up. This doesn't happen when
                the client's gateway generates identical 503 or other
                negative replies.</div>
              <div><br>
              </div>
              <div>I suspect this is happening because the To-tag in the
                Kam generated 503 reply doesn't match with the To-tag
                that previously was forwarded from the client's gateway
                to the upstream provider in the `180 Ringing`.</div>
