<h3>Description</h3>
<p>I have configured a kamailio as PCSCF taking the configuration sample files (kamailio.cfg and pcscf.cfg) in <a href="https://github.com/kamailio/kamailio/tree/master/misc/examples/pcscf">https://github.com/kamailio/kamailio/tree/master/misc/examples/pcscf</a></p>
<p>The version of kamailio installed is the 5.1.</p>
<p>When I perform "service pcscf start" the services doesn't restart giving a parsing error for a pseudo variable called $uac_req. The error is found in this section:</p>
<p>route[NATPING] {<br>
route(preload_pcscf);</p>
<pre><code>sht_iterator_start("nat_iterator", "natping");
while(sht_iterator_next("nat_iterator")) {
        xlog("OPTIONS to $shtitval(nat_iterator) via $shtitkey(nat_iterator)...\n");
        $uac_req(method) = "OPTIONS";
        $uac_req(ruri) = $shtitval(nat_iterator);
        $uac_req(furi) = PCSCF_URL;
        $uac_req(turi) = $shtitval(nat_iterator);
        $uac_req(ouri) = $shtitkey(nat_iterator); 
        $uac_req(evroute) = 1;
        uac_req_send(); 
}
sht_iterator_end("nat_iterator");
</code></pre>
<p>}</p>
<p>I have checked that I have only one "uac.so" file in /usr/lib64/kamailio/modules/ and the date of the file is April 15th. So I guess that the file is updated.</p>
