[SR-Users] RLS issue

Thu Dec 16 13:36:24 CET 2010

Hi everybody,

I'm using the Kamailio RLS+Presence module integrated with OpenIMSCore.

All the servers are running properly but when sending a RLS subscribe. 
The flow of SIP messages is the following:

A.1) Watcher ---- SUBSCRIBE (rls-services uri) ---> RLS

The step B.5 is sent directly to the presentity testuser01. Instead of 
that, I thought that message was suppose to be sent to the presence 
server in the URI that is shown in Contact header.
