you should be able to use usrloc's function:

1.15.  ul_register_ulcb(type ,callback, param)

The function register with USRLOC a callback function to be called when some event occures inside USRLOC.

Meaning of the parameters is as follows:

  • int types - type of event for which the callback should be called (see usrloc/ul_callback.h).

  • ul_cb f - callback function; see usrloc/ul_callback.h for prototype.

  • void *param - some parameter to be passed to the callback each time when it is called.

db_mode is already set to 2. There is one parameter I saw which is saying about cleaning expired db records so I set it to Enabled.
But it did not change anything.

modparam("usrloc", "db_timer_clean", 1)

Hello,

have a look to the db_mode parameter in the usrloc module. You can operate the module in different database modes.

Cheers,

So I tried the the Expires header for UNREGISTER and it is working fine. Thanks for that. But the problem is that SIP Phone does not send UNREGISTER event. It only sends REGISTER method periodically. So in my Server it will be always online. So to overcome that I will be running e cron job which will pool the online users from 'location' table of kamailio mysql db. But the problem is, 'location' table does not get updated as soon as possible, rather if I disconnect the SIP Phone and do 'kamctl ul show' it will be still there for like 5 mins, after that it goes away. How can I change the timeout of this,say to 2mins, meaning that after 2mins if there is no response from the client ,Kamailio will mark it as offline. Where to change that parameter?

Hello,

you can get the result of the register module "save()" function call from its return value:

https://www.kamailio.org/docs/modules/5.2.x/modules/registrar.html#registrar.f.save and then use a similar logic like you quoted in the initial question.

You can of course also just query the usrloc module with the provide remote function API:

https://www.kamailio.org/docs/modules/5.2.x/modules/usrloc.html#usrloc.r.lookup

This can be called over HTTP, JSON HTTP and others.

Cheers,

Henning

Kindly look into the snippet above. The bold lettered one. At that point can I assume authentication is successful ??

you should be doing some sort of authentication and then saving the user's registration data.
add a route to fire an event when the registration data is saved.
or even better IMO would be to use an event queue like mqueue and rtimer to push events into a queue and process them with rtimer and evapi

But it does not tell me if thats a successful register. I can make the user online but may be the request fails as credentials are wrong. So the REGISTER is not successful. How can I handle that?

Just as you do is_method(“INVITE”) you can do is_method(“REGISTER”) after that you can check the EXPIRE, if it is zero then it is an UN-REGISTER.

Though I have already a NodeJS server running, I will try the evapi module. If there are some tutorial/Wiki on how to do this please share that with me. That will be great help.

I would recommend using `evapi` for something like this
You could build a small go app that connects via evapi and send/receive events to/from kamailio.

Hi,
I  am integrating Kamailio into my application. I want to hook to the successful REGISTER and unregister event into Kamailio into my application. For now, I am able to hook into INVITE event and can hit my server to send a email to the callee user that user X is calling you. The way I am doing is by this
        if (is_method("INVITE")) {
                xlog("LOG_LOCAL3","L_INFO","invite came ($fU) ($tU)");
                $var(res) = http_connect("sipnodejsserver", "/","text/plain","src_user:$fU,dst_user:$tU" ,"$avp(route)");
                xlog("LOG_LOCAL3","L_INFO","request sent $avp(route)  $var(res)");
                setflag(FLT_ACC); # do accounting
        }

I need to show into my application that their SIP phone is online or not. How can I hook into this?
