<tt>Hi,<br>
<br>
Just to update the list with the outcome of this investigation.<br>
</tt><br>
<tt>The problem is generated by an ambiguity in WS/WSS specs (RFC
7118) which state that a WSS client must advertise "transport=ws"
- this is really confusing for a SIP proxy which has no clue on
which transport (WS or WSS) to use to reach the user.<br>
<br>
Most of the WSS UAC decided to disobey the IETF specs and to
actually advertise wss. See the case for SIPjs:<br>

href="https://github.com/onsip/SIP.js/issues/97" target="_blank">https://github.com/onsip/SIP.<wbr>js/issues/97</a>
<br>
<br>
After updating the SIP.js client, the call flow works like a charm.<br>
<br>
Best regards,<br>

<tt>Thank you Dragomir,<br>
<br>
So, there is an existing connection to your browser. <br>
<br>
Please redo the list_tcp_conns and send me the capture of the
BYE request received by OpenSIPS.<br>

<br>
So, the problem is about the BYE. Just before sending
BYE from Zoiper, please run on your opensips:<br>
opensipsctl fifo list_tcp_conns<br>
<br>
Lets see if your SIP.JS still has a connection to
OpenSIPS at that point.<br>
<br>
