    <font face="monospace">Hi,<br>

      <br>

      The CANCEL is internally generated as it goes hop-by-hop (when

      using transaction stateful mode).<br>

      <br>

      How do you change the FROM/TOÂ  URIs? if you change them with the

      uac_replace_to/from functions, the CANCEL will be accordingly

      generated, no need for any manual intervention. <br>

      <br>

      Regards,<br>
