<p>I was able to verify the <code>async(rest_client(...), resume)</code> returns <code>$var(rcode)</code> of 404 with the following route:</p>
<pre><code>route [resume] {
if ($rc < 0) {
xlog("Error code $var(rcode) in HTTP GET!\n");
send_reply("403", "GET Forbidden");
exit;
}
}
</code></pre>
<pre><code>Apr 24 16:20:18 localhost opensips[2141]: Error code 404 in HTTP GET!
</code></pre>
