The Call Statistics screen displays counters statistics and voice-quality metrics in these ways:

•During call—You can view the call information by rapidly pressing the ? button twice.

•After the call—You can view the call information captured during the last call by displaying the Call Statistics screen.

Note 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 not available on the phone. For more information about remote monitoring, see Chapter 8, “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.
