Description
Field
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
Quality Monitoring, on page 221
.
The MOS LQK score can vary based on the type of codec that the
Cisco Unified IP Phone uses.
Note
MOS LQK
Average MOS LQK score observed for the entire voice stream.
Avg MOS LQK
Lowest MOS LQK score observed from start of the voice stream.
Min MOS LQK
Baseline or highest MOS LQK score observed from start of the voice
stream.
These codecs provide the following maximum MOS LQK score under
normal conditions with no frame loss:
•
G.711 gives 4.5
•
G.729 A /AB gives 3.7
Max MOS LQK
Version of the Cisco proprietary algorithm used to calculate MOS LQK
scores.
MOS LQK Version
Total number of concealment frames divided by total number of speech
frames received from start of the voice stream.
CumConcealRatio
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.
IntConcealRatio
Highest interval concealment ratio from start of the voice stream.
MaxConcealRatio
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 5 percent concealment events (lost
frames) from the start of the voice stream.
SevConcealSecs
Information about outbound and inbound previous and current frames.
