Hello,
$expires(min) can be used to see if there is an unregistration going on:
- https://www.kamailio.org/wiki/cookbooks/4.4.x/pseudovariables#expires_key_-_expires_values
It is more safe to use this variable because expire value can be either as Expires header or as parameter in Contact header.
Cheers,
Daniel
Hi Alexandru,
The Expire header in Register can be your clue here. if it is greater than 0 means its a registration attempt. If the value is 0 then it is un-register request.
This is how you can catch this.
if(is_method("REGISTER") ) {if($hdr(Expire) == 0) {// Un-Registering User $fU} else {
// Register request
}}
I'd say put it somewhere just before the save("lcoation"); line.
The event for contact-expired will work for a user when its expires timer exceeds and there is no registration refresh from the device and hence Kamailio removes the contact from usrloc records.
Regards,Sammy

Hello list,
I need to send to an external API events when user is registrated and de-registrated.
As far as I understand standart behaviour is as follows:
If user is not registered, he sends REGISTER and he is registrated (I can catch that because I make the auth).
If user is registered and sends REGISTER he is de-register.
(Please correct me if I'm wrong.)
How can I catch that?
Can I use event_route[usrloc:contact-expired]?
Thanks in advance!
