Voice Quality Metrics
Total number of concealment frames divided by total number of speech frames
that were received from the start of the voice stream.
Cumulative Conceal Ratio
Ratio of concealment frames to speech frames in preceding three-second interval
of active speech. If voice activity detection (VAD) is in use, a longer interval
might be required to accumulate 3 seconds of active speech.
Interval Conceal Ratio
Highest interval concealment ratio from start of the voice stream.Max Conceal Ratio
Number of seconds that have concealment events (lost frames) from the start
of the voice stream (includes severely concealed seconds).
Conceal Secs
Number of seconds that have more than five percent concealment events (lost
frames) from the start of the voice stream.
Severely Conceal Secs
When the RTP Control Protocol is disabled, no data generates for this field and thus displays as 0.Note
