Regarding `Via: SIP/2.0/WSS` I want to add, that the SIP-client connects to the webserver over secured websockets. The webserver (nginx) forwards the request to Kamailio over insecured TCP/HTTP connection. Thus: the sip client thinks it is using WSS,, but Kamailio sees a WS-only connection. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3351#issuecomment-1407415602 You are receiving this because you are subscribed to this thread.
