Cisco 8832 Maintenance

The ping destination allows only alphanumeric characters, ‘-’, and “_” (underscores). Otherwise the phone
shows an error on the web page. If the <ping destination> includes spaces, the phone uses only the first part
of the address as the pinging destination.
For example, to ping the 192.168.1.1 address:
http://<Phone IP>/admin/ping?192.168.1.1
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.
Note
You can access voice quality metrics from the Cisco IP Phone using the Call Statistics screen or remotely by
using Streaming Statistics.
