                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.  I'd like to establish a
                      regular OPTIONS polling interval for a known list
                      of endpoints.  I'm not aware of any internal
                      mechanism that will achieve this.  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.
                       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?  Or, any other thoughts?</div>
