Example
  This example creates a new RTCPeerConnection which will use a
  TURN server at turnserver.example.org to negotiate
  connections. Logging into the TURN server will use the username "webrtc" and the
  creative password "turnpassword".
const myPeerConnection = new RTCPeerConnection({
  iceServers: [
    {
      urls: "turn:turnserver.example.org",  // A TURN server
      username: "webrtc",
      credential: "turnpassword",
      credentialType: "password"
    }
  ]
});
