LQK scores.
Cumulative Conceal Ratio
Total number of concealment frames divided by total number of
speech frames received from start of the voice stream.
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 might 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.
Network Protocol
Identifies the current Network Protocol—IPv4.
