Streaming Statistics
Interval Conceal Ratio Ratio of concealment frames to speech frames in preceding 3-second interval of active speech. If
using voice activity detection (VAD), a longer interval may be required to accumulate 3 seconds of
active speech.
Max Conceal Ratio Highest interval concealment ratio from start of the voice stream.
Conceal Secs Number of seconds that have concealment events (lost frames) from the start of the voice stream
(includes severely concealed seconds).
Severely Conceal Secs Number of seconds that have more than 5 percent concealment events (lost frames) from the start of
the voice stream.
Latency
1
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.
Max Jitter Maximum value of instantaneous jitter, in milliseconds.
Sender Size RTP packet size, in milliseconds, for the transmitted stream.
Sender Reports
Received
1
Number of times RTCP Sender Reports have been received.
Sender Report Time
Received
1
Last time at which an RTCP Sender Report was received.
Rcvr Size RTP packet size, in milliseconds, for the received stream.
Rcvr Discarded RTP packets received from network but discarded from jitter buffers.
Rcvr Reports
