    <tt>Hi Daniel,<br>
      <br>
      Without a pcap showing the signaling is hard to understand (not to
      mention helping) your scenario. Please provide a link to the pcap
      or ngrep.<br>

      Regards,<br>

        Hey
        <div><br>
        </div>
        <div>I had a problem when receiving simultaneous CANCEL from
          customer and 200 OK from gateway.</div>
        <div><br>
        </div>
        <div>Seems that the first CANCEL was rejected, but the second
          CANCEL was accepted. This second CANCEL did NOT go to the
          gateway, just Opensips received and replied with 200 OK.</div>
        <div><br>
        </div>
        <div>This is the log of the first CANCEL:<br>
