• Chrome 67*
• Safari 11.1.1
• Mobile Safari iOS 11.4 (*webview is not supported)
• Firefox 61*
• Opera 54 (chrome67)
• Edge 42 (without Call.broadcast)

• Renegotiation doesn't work between chrome 67 & firefox 61 because of SDP incompatibilities. Chrome still implements PlanB and firefox use Unified plan: https://bugs.chromium.org/p/chromium/issues/detail?id=465349 This should be solved in M-69 For now, the solution is to add both tracks (audio&video) before the first sdp offer&answer is being sent and disable them if needed.
• rtcpMuxPolicy negotiate is not supported by Edge - use require instead
• negotiationNeededDisabled turn on to disable in call renegotiation (which does't work between Chrome&Safari)
