Hi,
Just to update the list with the outcome of this investigation.
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.
Most of the WSS UAC decided to disobey the IETF specs and to actually
advertise wss. See the case for SIPjs:
https://github.com/onsip/SIP.js/issues/97
<https://github.com/onsip/SIP.js/issues/97>
After updating the SIP.js client, the call flow works like a charm.

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

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

Hi Bogdan,
Thanks for the detailed and comprehensive answer.
Zoiper talking (connection is established) with SIP.JS
Zoiper ---(over UDP)--> Opensips --(over WSS)---> SIP.JS
Why not possible Opensips send BYE to SIP.JS over established
connection?
Why all is OK when SIP.JS send BYE?
I need help to setup Opensips to solve this problem.
Best regards,
Dragomir

Hello,
I have problem with "topology_hiding_match()" and WSS.
Zoiper ---(send BYE)--> Opensips --(can not relay to)--->
SIP.JS
Here part ot script:
if (has_totag()) {
if (topology_hiding_match()) {
t_relay();
exit;
}
...
Opensips receive BYE. When execute "t_relay()" give follow
