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
Note
Average MOS LQK score observed for the entire voice stream.
Lowest MOS LQK score observed from start of the voice stream.
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:
For Cisco Unified IP Phone 7975G, 7965G, and 7945G:
• G.711 gives 4.5.
• G.722 gives 4.5.
• G.728/iLBC gives 3.9.
• G.729 A/AB gives 3.8.
For Cisco Unified IP Phone 7971G-GE and 7970G:
• G.711 gives 4.5
• G.729 A /AB gives 3.7
