<br>
Thanks a lot for your response!<br>
<br>
I've been thinking about it and there's something abnormal. Firs,
the RLS is suppose to send the initial SUBSCRIBE to the S-CSCF
instead of sending it to the I-CSCF. Then, I don't know why the
S-CSCF translates the SUBSCRIBE URI (<a
class="moz-txt-link-freetext" href="sip:testuser02@open-ims.test">sip:testuser02@open-ims.test</a>)
to <a class="moz-txt-link-rfc2396E"
href="sip:testuser01@155.54.190.245:8060;rinstance=9b7761b4bcaa4bd0">"sip:testuser01@155.54.190.245:8060;rinstance=9b7761b4bcaa4bd0"</a>.
All the routing is the default configuration of both cscfs and rls.<br>
<br>
How can I change the routing of the RLS in order it to send the
SUBSCRIBE messages to the S-CSCF?<br>
<br>
Here's the configuration file:<br>

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

If the P-CSCF is not forwarding the request as supposed, I guess
you have to fix the routing on the P-CSCF.
