<tt>Hello Jeff,<br>
<br>
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">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>
