Hi Robert! Verto is able to connect to our STUN/TURN server from both Chrome and Firefox (at least on Win10) using the following format: iceServers: [ { urls: 'stun:((domain of STUN server)):443', }, { urls: "turn:((domain of TURN server)):443?transport=tcp", username: "((username for TURN server))", credential: "((password for TURN server))" } ] Btw, the port and transport above are configured in our coturn to ensure we support TURN TLS.

STUN = !!moz ? { urls: ['turn:xxx'], username: 'yyy', credential: 'zzz' } : { url: 'turn:xxx', username: 'yyy', credential: 'zzz' } ; Robert
