Call Statistics Screen
The Call Statistics screen displays counters statistics and voice quality metrics in these ways:
• During call—You can view the call information by pressing the ? 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
Chapter 7,
“Monitoring the Cisco Unified IP Phone Remotely.”
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.
To display the Call Statistics screen for information about the last voice stream, follow these steps:
Procedure
Step 1 Press the Settings button.
Step 2 Select Status.
Step 3 Select Call Statistics.
To exit the Call Statistics Screen screen, press the Exit softkey.
The Call Statistics Screen displays the items shown in 6-4.
