<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m trying to implement RLS with integrated XCAP server. I have successfully run the Kamailio instance with the following snippet.<o:p></o:p></p>
<p class="MsoNormal">Since I had no RLS clients available, I have tried to test this with SIPp. The attached pcap trace is the result.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Test:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">1.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Send an XCAP signal over http to Kamailio.<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">2.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Register and subscribe Kamailio.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">When I sent the Subscribe with sipp, the server throws error that subscription was not found in the database.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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?<o:p></o:p></p>
