title: Load new module in Kamailio
body: <p>I would like to ask, how can I load new module in Kamailio 4.1.2?
  Actually, I have an issue, when I tried to compile my <code>kamaiio.cfg</code>
  I've got error:</p>
  
  <pre><code>root@kamailio:/usr/local/# kamailio -c kamailio.cfg
  loading modules under /usr/local/lib64/kamailio/modules/
   0(25392) ERROR: &lt;core&gt; [sr_module.c:587]: load_module(): ERROR: load_module: could not find module &lt;websocket&gt; in &lt;/usr/local/lib64/kamailio/modules/&gt;
   0(25392) : &lt;core&gt; [cfg.y:3408]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 323, column 12-25: failed to load module

  ERROR: bad config file (2 errors)
  </code></pre>
  
  <p>when I look physically to the <code>/usr/local/lib64/kamailio/modules/</code> there is some modules, but <code>websocket.so</code> is missing.
  So, how can I get and load module in Kamailio?</p>
  
  <p>Thank you for help! </p>
