Chapter 9      Troubleshooting and Maintenance

Monitoring the Voice Quality of Calls

Using Voice Quality Metrics

To use the metrics for monitoring voice quality, note the typical scores under 
normal conditions of zero packet loss, and use the metrics as a baseline for 
comparison. 

It is important to distinguish significant changes from random changes in metrics. 
Significant changes are scores that change about 0.2 MOS or greater and persist 
in calls that last longer than 30 seconds. Conceal Ratio changes should indicate 
greater than 3 percent frame loss. 

MOS LQK scores can vary based on the codec that the Cisco Unified IP Phone 
uses. The following codecs provide these maximum MOS LQK scores under 
normal conditions with zero frame loss:

•

G.711 codec gives 4.5 score

•

G.729A/ AB gives 3.8 score

•

G.728/iLBC gives 3.9 score

Note

•

CVTQ does not support wideband (7 kHz) speech codecs, as ITU has not 
defined the extension of the technique to wideband. Therefore, MOS scores 
that correspond to G.711 performance are reported for G.722 calls to allow 
basic quality monitoring, rather than not reporting an MOS score. 

•

Reporting G.711-scale MOS scores for wideband calls through the use of CVTQ 
allows basic quality classifications to be indicated as good/normal or 
bad/abnormal. Calls with high scores (approximately 4.5) indicate high 
quality/low packet loss, and lower scores (approximately 3.5) indicate low 
quality/high packet loss.

•

Unlike MOS, the Conceal Ratio and Concealed Seconds metrics remain valid 
and useful for both wideband and narrowband calls.

A Conceal Ratio of zero indicates that the IP network is delivering frames and 
packets on time with no loss.
