                <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>
                      <a class="m_-5872086569655355815m_-3570097487231027143m_404293194474949616moz-txt-link-freetext" href="https://github.com/onsip/SIP.js/issues/97" target="_blank">https://github.com/onsip/SIP.j<wbr>s/issues/97</a>
                <br>
                <br>
                After updating the SIP.js client, the call flow works
                like a charm.<br>
