<p>Hello,<br>
</p>
if you set use_received param for path module, then the received
address in Route header is set as dst uri, see:<br>
<br>
-
<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><br>
<br>
All you need to do is:<br>
<br>
loose_route();<br>
t_relay();<br>
<br>
Note that loose_route() is dealing with a pre-loaded Route header in
this case, see the readme of rr module for the return code.<br>
<br>

<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>
