Note
A single call can have multiple voice streams, but data is captured for only the last voice stream. A voice stream is a packet stream between two endpoints. If one endpoint is put on hold, the voice stream stops even though the call is still connected. When the call resumes, a new voice packet stream begins, and the new call data overwrites the former call data.
For information about using the voice quality metrics, see the "Monitoring the Voice Quality of Calls" section on page 8-23.
To display the Call Statistics screen for information about the last voice stream, follow these steps:
Procedure

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 8-23.
Note
Avg MOS LQK
Average MOS LQK score observed for the entire voice stream.
Min MOS LQK
Lowest MOS LQK score observed from start of the voice stream.
Max 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:
•
•
MOS LQK Version
