Voice Quality Metrics
Score that is an objective estimate of the mean opinion score (MOS)
for listening quality (LQK) that rates from 5 (excellent) to 1 (bad).
This score is based on audible concealment events due to frame loss
in the preceding 8-second interval of the voice stream.
The MOS LQK score can vary based on the type of codec
that the Cisco Unified IP Phone uses.
Note
MOS LQK
Lowest MOS LQK score observed from start of the voice streamMin MOS LQK
Version of the Cisco proprietary algorithm used to calculate MOS
LQK scores
MOS LQK Version
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
Number of seconds that have concealment events (lost frames) from
the start of the voice stream (includes severely concealed seconds)
