    <div class="moz-cite-prefix">We need to know when the phones have
      gone AWOL.<br>
      <br>
      Without this scheme, we are getting mysterious cases of phones not
      ringing when the ISP is having a bad hair day.<br>
      This doesn't exactly fix the problem, but it does enable us to
      alert the user who can then take appropriate measures.<br>
      <br>
      I suppose if it was just a temporary glitch, we've just made it a
      permanent one....<br>
      <br>
      Mmm.<br>
      <br>
      Given that some phones seem to be far more susceptible to this
      than others, there could be a babies with bathwater issue. Might
      have to rethink the strategy here, but the most important thing is
      to look out for failed OPTIONS responses.<br>
