                There is nothing existing to do the kind of job you
                describe.<br>
                <br>
                A working solution is to have an external script that
                checks all the endpoints by sending an OPTIONS request
                via the MI interface (see the t_uac_dlg MI command from
                TM module).<br>
                Depending of the received reply, you can determine the
                status of the end-point.<br>
                <br>
                Regards,<br>

                    <div>I'm looking for a way to identify hosts that
                      are no longer available in cases where
                      registration is not used. &nbsp;I'd like to establish a
                      regular OPTIONS polling interval for a known list
                      of endpoints. &nbsp;I'm not aware of any internal
                      mechanism that will achieve this. &nbsp;The dialog
                      module comes close with its "p" and "P" options on
                      <a moz-do-not-send="true"
href="http://www.opensips.org/html/docs/modules/devel/dialog.html#id294985"
                        target="_blank">create_dialog()</a>, but that's
                      for calls/dialogs that are already in process to
                      detect an endpoint that falls off the network.
                      &nbsp;I'd like to have this pinging outside of any
                      other SIP activity independent of established
                      transactions or dialogs.</div>
                    <div><br>
                    </div>
                    <div>Does it make sense to approach this with a
                      custom B2B scenario we can invoke via cron over an
                      MI interface? &nbsp;Or, any other thoughts?</div>
