Viewing Call Statistics
You can access the Call Statistics screen on the phone to display counters, statistics, and voice quality
metrics in these ways:
• During call—You can view the call information by pressing the Select 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 9,
“Monitoring the Cisco Unified Wireless 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 SETTINGS > Status.
Step 2 Scroll to and select Call Statistics; the list of statistics appears.
Step 3 Use the Navigation button to scroll through the items in the Call Statistics screen.
Table 8-6 describes the items that appear in this screen.
Step 4 To exit the Call Statistics screen, press the Back softkey.
