<div>Hello,</div><div><br></div><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 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><div><br></div><div><br></div><div>- Jeff</div><div><br></div>
