Voice Quality Monitoring

To measure the voice quality of calls that are sent and received within the network, Cisco IP Phones use these

statistical metrics that are based on concealment events. The DSP plays concealment frames to mask frame

loss in the voice packet stream.

• Concealment Ratio metrics—Show the ratio of concealment frames over total speech frames. An interval

• Concealed Second metrics—Show the number of seconds in which the DSP plays concealment frames

Note

Concealment ratio and concealment seconds are primary measurements based on frame loss. A Conceal Ratio

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

conceal ratio is calculated every 3 seconds.

due to lost frames. A severely "concealed second" is a second in which the DSP plays more than five

percent concealment frames.
