<p>Hello,<span style="font-size:12.0pt;mso-fareast-language:DE"><o:p></o:p></span></p>
<p>1. for websocket the connection has to be reused, the server cannot open a connection towards the browser. So you don't have to force any socket, if kamailio doesn't find the address matching the target ws address, then will throw an error, otherwise will
use it.<o:p></o:p></p>
<p>2. have you enabled xhttp and websocket modules properly?<o:p></o:p></p>
<p>Cheers,<br>
Daniel<o:p></o:p></p>
