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@sip.server" xmlns="urn:ietf:params:xml:ns:rlmi" version="1" fullState="true"> <resource uri="sip:user2@sip.server"/> <resource uri="sip:user3@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!
Regards, Alex.
