Call Statistics Screen
You can access the Call Statistics screen on the phone to display counters, statistics, and voice quality metrics as shown in Table
•During call, you can display the call information on the phone screen by pressing the i or ? button twice rapidly.
•After the call, you can view the call information captured during the last call by displaying the Call Statistics screen.
Note You can remotely view the call statistics information by using a web browser to access the Streaming Statistics web page. For more information about remote monitoring, see the “Streaming Statistics” section on page
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
