[SR-Users] Endpoint registration tracking and reporting

[Nick Raper]

Hi Daniel,

Thank you this is exactly what I was looking for. We are using version Kamailio v3.3.3 and although Kamailio starts without any errors, I don’t get the ‘expired contact for’ syslog entry.

If I use ‘event_route[htable:mod-init]’ then I can write a sylog entry without a problem.

So it seems that ‘event_route[usrloc:contact-expired]’ might not work in version 3.3.3, is this correct?

Regards,

Hello,

if you use recent versions, there is an event route exported by registrar module where you can write a log message or do some other action when a contact expires:

- http://kamailio.org/docs/modules/stable/modules/registrar.html#idp2012416

Maybe you can hook something there that will make it easier for you to track non-registering devices.

Moreover, there is an option (when combined with nathelper module) to remove the record from location table when a device is not replying to OPTIONS keepalive requests. In this way you can discover faster when a device connectivity is lost.

On the other hand, there is no way to contact the device and tell to re-register.

Cheers,
Daniel

Hi all,
?
What is the best way to monitor endpoint registrations?
?
When one of our clients has a link failure or for some reason they lose their SIP registration with Kamailio, we?d like to be able to see this so that we can respond and get the trunk re-registered.
?
We do monitor the physical links but endpoints, (usually Asterisk based), often don?t re-register after connectivity is restored.
?
I was thinking of a script that dumps the ?location? table every 10 minutes and compares it to the previous ?location? table dump and reports on the changes.
?
Is there a better way of doing this?
?
Regards,
