<p class="MsoNormal" style="margin-left:35.4pt">Hello,<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:35.4pt">There are times that our S-CSCF module just wont start. I’ve tried correlating the issue with some operation such as not de-registering an IMS client (Boghe or imsdroid) prior to shutting down the Kamailio server.
But this isn’t always the case. Being that we are running this an a Ubuntu Virtual Machine, simply overwriting the image with a backed up VM is the temporary solution.

<p class="MsoNormal" style="margin-left:35.4pt"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:35.4pt">I’ve dropped and created the db for S (kamdbctl) and rearranged the order of loading the presence module with same result.<o:p></o:p></p>
