We think the problem is related to the instruction "rtcConfiguration.isObject()" Line 58. 1318971 1 jonlee 2017-06-13 19:26:30 -0700 Spec has changed a bit since this was first reported. 1319022 2 youennf 2017-06-13 23:40:21 -0700 Instead of doing "new RTCPeerConnection(servers, pcConstraint);", you might need to use https://www.w3.org/TR/webrtc/#dom-rtcconfiguration dictionary. That would end-up with something like: "new RTCPeerConnection({iceServers: servers, ... });" Also "servers" must use "urls" and not "url" as per https://www.w3.org/TR/webrtc/#dom-rtciceserver.
