Voice Quality Metrics
MOS LQK
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. For more
information, see the
“Monitoring the Voice Quality of Calls”
section on page 10-12
Note
The MOS LQK score can vary based on the type of codec
that the Cisco Unified IP Phone uses.
Min MOS LQK
Lowest MOS LQK score observed from start of the voice stream
MOS LQK Version
Version of the Cisco proprietary algorithm used to calculate MOS
LQK scores
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
Conceal Secs
Number of seconds that have concealment events (lost frames) from
the start of the voice stream (includes severely concealed seconds)
