<p>Hi Walter,</p>
<p>Just as a coincidence I had the same issue last month. I tested
two solutions:</p>
<p>1. Make a dummy trunk and add outbound CLI rules to 'capture' the
disallowed traffic. The dummy trunk can just be a default Kamailio
instance with the line</p>
<p>sl_send_reply("403","CLI not allowed");<br>
</p>
<p>I tested with another system, but you can also add a Kamailio
instance locally on a different port.</p>
<p>2. Make a list of rewrite rules and rewrite all forbidden CLI's
to a special like 'forbidden'. Then you can add some custom code
in the proxy to reply with 403.</p>
<p>I'm using the last one, but I've added the custom code in another
(Kamailio) proxy that handles my traffic to this provider:</p>
<p> if ($fU=="forbidden")<br>
{<br>
# Illegal CLI, determined with rewrite rules<br>
sl_send_reply("403","This CLI is not allowed");<br>
exit;<br>
}</p>
<p>I've imported the rules directly in
provisioning.voip_rewrite_rules as the UI is not suited to add
around 100 rules I have.<br>
</p>
<p>Hope this helps,</p>
<p>Regards,</p>
<p>Henk Plessius</p>

<div>We need to block inbound calls based on CallerID. Is there
a "global" version, or a list which I can apply to multiple
peers and subscribers (some sip trunk customers have wildcard
caller-id).<br clear="all">

</div>
<div>I was hoping on Admin NCOS, but that only blocks on
outgoing calls. (on called number).</div>

Hope some of you have some idea?</div>
