DescriptionItem
Baseline or highest MOS LQK score observed from start of the voice stream.
These codecs on the Cisco Unified IP Phones 7962G and 7942G provide the
following maximum MOS LQK score under normal conditions with no frame
loss:
•
G.711 gives 4.5
•
G.722 gives 4.5
•
G.728/iLBC gives 3.9
•
G.729 A/AB gives 3.8
These codecs on the Cisco Unified IP Phones 7961G/G-GE and
7941G/41G-GE 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.
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 (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.
