You can use an event hook from mod_lua to execute a lua script on unregister event.
Add "<hook event="custom" subclass="sofia::unregister" script="logout_callcenter.lua" />" in lua.conf.xml

In the script you can do whatever you want, for example logout from callcenter.
>>freeswitch.consoleLog("INFO","Executing logout_callcenter.lua\n");
>>local username = event:getHeader("username");
>>local from_user = event:getHeader("from-user");
>>freeswitch.consoleLog("INFO","username: " .. (username or "") .."\n");
>>freeswitch.consoleLog("INFO","from-user: " .. (from_user or "") .."\n");
>>
>>if (username ~= nil) then
>>    api = freeswitch.API();
>>    result = api:execute("callcenter_config", "agent set status "..username.." 'Logged Out'");
>>    freeswitch.consoleLog("INFO", "Execute on unregister: ".. result .. "\n")
>>end

Still no luck on this and I really need to know date/time when a particular extension is unregistering. Anyone else have an idea that does not involve programming? Thanks,

I have been searching the wiki and web and still nothing simple to log de-registrations. I find it hard to believe there is not a simple way to do this, anyone have a good idea?

Hmmmm…. Logging de-registrations would be a useful enhancement to FreeSwitch for debugging issues like this. I know a SIP trace does it but that’s a LOT of data when we're talking days. Thanks.

Here's some old nodejs code relying on `esl` lib to monitor for de-registrations and send me an email. I haven't used it in ages.

Does anyone know if there is something I can do to log device registrations, and more importantly when devices lose registration, without having a ton of other log data. I know I can turn on a higher level of diagnostics, but it may be several days before I find what I need and don’t want to flood the log.

I am working with Counterpath on Bria Push service and need to find when their push server stops registering. Since they don’t send a notification for that and it’s not in the normal FS log, I may not know for days when this happens. It would be nice to be able to scan the log for lost registrations. Thanks!
