      We seem to be experiencing problems with phones (so far only
      Grandstream GXP2000s) falling off the list of registered SIP
      clients.<br>
      I'm presuming that this is because they're failing to re-register
      within the previously agreed registration lifetime.<br>
      Any tips on debugging this would be useful, but I'm going to start
      by setting a very short timeout on the phone and watching to see
      what happens on the server.<br>

      <p>A session timeout is normally a timeout on a phonecall of I
        remember correctly (offerde by fs on outgoing calls. It is
        negotiated). The registration lifetime is another One.</p>

          <div text="#000000" bgcolor="#FFFFFF"> We're trying to
            understand SIP registration timeouts.<br>
            <br>
            When we do a sofia status profile internal reg, one of the
            lines includes something like this:<br>
            <br>
            <table style="font-family:'Times New
Roman';letter-spacing:normal;text-indent:0px;text-transform:none;word-spacing:0px">
              <tbody>
                <tr>
                  <td>Status</td>
                  <td>Registered(UDP)(unknown) EXP(2013-04-22 17:22:00)
                    EXPSECS(1796)</td>
                </tr>
              </tbody>
            </table>
            <br>
            It seems that when a phone registers, it says how long
            Freeswitch should retain the registration for (in this case
            there's half an hour left).<br>
            <br>
            What is the relationship between this mechanism and the one
            in config of the sip profile:<br>
            <br>
            &lt;param name="session-timeout" value="1800"/&gt;<br>
            <br>
            Or is this a totally different kind of session?<br>
