Hello,
I have partly fixed this, I was using an incorrect xml format and missing usage of pua
module. It took a little more than debugging to find this out.
Now I have run into this new issue.
I have implemented a presence + rls + xcap server:
When client subscribes for RLS, kamailio Notifies with resourcelist for the client. The
pua within the server does backend subscribtions.
These backend subscribtions are responded with 202 Accepted replies.
When the resources in the contact list change their presence information the pua generates
NOTIFIY with subscription state: pending.
Rls module does not reply back.
Kamailio does not return from the following command.
if(is_method("NOTIFY"))
{
xlog("handle notify");
rls_handle_notify();
xlog("notify was handled");
exit;
};
Thank you for looking into this.
Regards
Gnani

Subject: How does RLS work with kamailio.
Hello,
I'm trying to implement RLS with integrated XCAP server. I have successfully run the
Kamailio instance with the following snippet.
Since I had no RLS clients available, I have tried to test this with SIPp. The attached
pcap trace is the result.
Test:
1. Send an XCAP signal over http to Kamailio.
2. Register and subscribe Kamailio.
The test does store the xml received over http in the xcap table in the database. But rls
module does not store the data neither in rls_presentity or rls_watcher.
When I sent the Subscribe with sipp, the server throws error that subscription was not
found in the database.
I would like to know if I'm doing something wrong to implement this service. Is there
any brief tutorial on how to implement this?
