[SR-Users] Need help with Kamailio+RLS configuration.

[Aleksandrs Semenenko]

Hello everyone,

I am running Kamailio 3.3.2 server and I need to configure it to support RLS to avoid big amounts of SUBSCRIBE requests from clients.

By this moment I have managed to configure XCAP server and learned the XML structure for press-rules, rls-services and resource-list documents.

Also I have successfully put rls_update_subs and rls_handle_subscribe calls to kamailio.cfg, so now when I PUT new rls-services or resource-list document to XCAP I can see these calls triggered.

The problem is that on client side I always get empty notification XML:

<?xml version="1.0"?>
<list uri="sip:user1-list at sip.server" xmlns="urn:ietf:params:xml:ns:rlmi" version="1" fullState="true">
  <resource uri="sip:user2 at sip.server"/>
  <resource uri="sip:user3 at sip.server"/>
</list>

As I understand, user2 and user3 must have added user1 to pres-rules document? Correct? So it is…

I assume there should be a call to rls_handle_notify function somewhere in kamailio.cfg, but where exactly?

I have tried to add it after SUBSCRIBE condition, but it is never called in fact:

        if( is_method("SUBSCRIBE"))
        {
                xlog("BEFORE rls_handle_subscribe");
                $var(ret_code)= rls_handle_subscribe();
                xlog("AFTER rls_handle_subscribe");

                if($var(ret_code)== 10)
                                handle_subscribe();

                t_release();
        }
        else 
        if (is_method("NOTIFY")) {
		xlog("BEFORE rls_handle_notify");
                rls_handle_notify();
		xlog("AFTER rls_handle_notify");
        }


Any comment would be appreciated!

Alex.
