While no specification change is required, it would be useful to add a Section 16 on WebRTC compatibility issues, so as to answer this and other potential WebRTC compatibility questions.  Here is the proposed text for a Section 16.1 within that section: 

16.1 Voice Activity Detection

[WEBRTC10] Section 4.2.4 defines the RTCOfferOptions dictionary, which includes the voiceActivityDetection attribute, which determines whether Voice Activity Detection (VAD) is enabled within the Offer produced by createOffer(). The effect of setting voiceActivityDetection to TRUE is to include the Comfort Noice (CN) codec defined in [RFC3389] within the Offer.

Within ORTC API, equivalent behavior can be obtained by configuring the Comfort Noise codec for use within the RTCRtpParameters object, or configuring a codec with built-in support for Comfort Noise (such as G.729) to enable comfort noise.
