of active speech. If using voice activity detection (VAD), a longer interval
might be required to accumulate 3 seconds of active speech.
Highest interval concealment ratio from start of the voice stream.
Number of seconds that have concealment events (lost frames) from the start
of the voice stream (includes severely concealed seconds).

Estimate of the network latency, expressed in milliseconds. Represents a
running average of the round-trip delay, measured when RTCP receiver report
blocks are received.
Maximum value of instantaneous jitter, in milliseconds.
RTP packet size, in milliseconds, for the transmitted stream.
Number of times RTCP Sender Reports have been received.
Last time at which an RTCP Sender Report was received.
RTP packet size, in milliseconds, for the received stream.
RTP packets received from network but discarded from jitter buffers.
Number of times RTCP Receiver Reports have been received.
Last time at which an RTCP Receiver Report was received.
