I am playing with websocketson Asterisk 11.5.0. I can connect over Http to the manager and standard TCP. I have make the config changes suggested here https://wiki.asterisk.org/wiki/display/AST/Asterisk+WebRTC+Support
curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: localhost" -H "Origin: http://localhost:8088" http://localhost:8088/ws
And get the response …
HTTP/1.1 400 Bad Request

Has anyone got any suggestion of things to try ?
