Cisco 7941G Administration Guide

DescriptionItem
Total number of concealment frames divided by total number of speech
frames received from start of the voice stream.
Cumulative 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.
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. This includes severely concealed seconds.
Conceal Secs
Number of seconds that have more than 5 percent concealment events
(lost frames) from the start of the voice stream.
Severely Conceal Secs
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.
