<p>Hello,</p>
<p>you have an explicit set of $fs, which is setting the send
socket. You have to do then when receiving from WS, not when going
to WS.</p>
<p>In 5.1, you can try to enable:</p>
<p> -
<a class="moz-txt-link-freetext" href="https://www.kamailio.org/docs/modules/stable/modules/path.html#path.p.enable_r2">https://www.kamailio.org/docs/modules/stable/modules/path.html#path.p.enable_r2</a></p>
<p>and then let kamailio do all about send socket (remove the
assignments to $fs).</p>
<p>Cheers,<br>
Daniel<br>

<div>I have configured sip over websockets and im able to
register to Freeswitcha via kamailio.</div>
<div>Also, i use add_path_received() so kamailio adds a path
