Hi Rocio,<div><br></div><div>As Carsten mentioned ISC is simpy SIP so you can configure your config file to forward to your SIP AS based on whatever method you want. What you won&#39;t have by default is the IMS trigger points (IFCs), etc which is IMS specific functionality.</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>
<br>
you may create a simple AS based on Kamailio without any extensions.<br>
I actually use a Kamailio as a Presence AS and another Kamailio as a<br>
(very limited) MMTel-AS in my IMS setup (although i will probably<br>
replace the MMTel-AS based on Kamailio with a solution based on SEMS<br>
in the near future).<br>
It depends on your requirements: As per IMS-specs, the AS should store<br>
it&#39;s data (e.g. Call-Forwarding) in via the Sh-Interface in the HSS.<br>
Kamailio (per se) has no options (yet) to do so.<br>
The ISC Interface is nothing else than SIP anyway.<br>

<div><div></div><div>&gt; Hello,<br>
&gt;<br>
&gt; I was wondering if it would be possible to plug an Application Server on<br>
&gt; Kamilio solution using the ISC interface (other than the AS module provided<br>
&gt; with Kamailio solution).<br>
&gt; Would it be mandatory to use IMS extensions to do so?<br>
&gt;<br>
&gt; Thank you.<br>
&gt;<br>
