voiceActivityFlag property of the
RTCRtpSynchronizationSource interface indicates whether or not the most recent RTP packet on the source includes voice activity. This is only present if the stream is using the voice activity detection feature; see the
var voiceActivity = RTCRtpSynchronizationSource.voiceActivityFlag
A Boolean value which is
true if voice activity is present in the most recently received RTP packet played by the associated source, or
false if voice activity is not present.
This property is omitted entirely if voice activity detection is not enabled on the source, or if the RFC 6464 extension header isn't present.
