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
conceal ratio is calculated every 3 seconds.
• Concealed Second metrics—Show the number of seconds in which the DSP plays concealment frames
due to lost frames. A severely “concealed second” is a second in which the DSP plays more than five
percent concealment frames.
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.
