Call Statistics Screen
You can access the Call Statistics screen on the phone to display counters, statistics, and voice-quality
metrics of the most recent call.
Note
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 latest voice stream, follow these steps:
