    <tt>Hi Alexey,<br>
      <br>
      Right now OpenSIPs can "unregister" contacts which are no longer
      answering to pinging (OPTIONS based). For the new upcoming release
      2.4 we are working to actively calculate the ping round trip and
      to be able to do multiple actions with it:<br>
       * raise events for notification (on certain roundtrip thresholds)<br>
       * during lookup(), ignore/select only certain contacts, based on
      their roundtrip.<br>
      <br>
      Regards,<br>
    </tt>

              Hello all.<br>
              <br>
              What is the best way to measure the quality of SIP
              connection between OpenSIPS as a registrar server and
              registered subscriber?<br>
              <br>
              Something like in Asterisk 'sip show peers', column
              'Status'.<br>
              <br>
              We have a great number of subscribers which are connected
              from GSM smartphones (via mobile internet). And we'd like
              to measure - if the delay is good enough, we will dial
              them via SIP. Otherwise via GSM.<br>
              <br>
              So, we need some tool to measure, but as I know, there
              isn't any in OpenSIPS, which work 'out of the box'.<br>
