        <div><br>
        </div>
        <div>I have 2 interfaces (udp:internal & a natted
          tls:external as xxx.xxx.xxx.xxx) and using drouting() to send
          sip OPTIONS to endpoints via both.</div>
        <div><br>
        </div>
        <div>I have been using the 'probing_from' parameter but I would
          like to change the from URI depending on which interface the
          OPTIONS request will be sent from.</div>
        <div><br>
        </div>
        <div>Is this possible? I am using 3.2</div>
        <div><br>
        </div>
        <div>Many thanks</div>
        <div>Mark.</div>
