Display Call Statistics Window
You can access the Call Statistics screen on the phone to display counters, statistics, and voice-quality metrics
of the most recent call.
You can also remotely view the call statistics information by using a web browser to access the Streaming
Statistics web page. This web page contains additional RTCP statistics that are not available on the phone.
Note
A single call can use 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 latest voice stream, follow these steps:
Procedure
Step 1

Step 2
