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 Step 2 Step 3 Press the Settings button. Select Status. 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.

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.
