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 9-17

Note

The MOS LQK score can vary based on the
type of codec that the
Cisco Unified IP Phone uses.

Avg MOS LQK

Average MOS LQK score observed for the entire
voice stream
