You can access the Video Statistics screen on the phone to display counters, statistics of the most recent call.
You can also remotely view the video 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.
For more information about remote monitoring, see Cisco IP Phone Web Page, on page 284.
Note
A video stream is a frame stream between two endpoints. If one endpoint pauses the video streaming, the
video stream stops even though the call is still connected. When the video streaming resumes, a new video
frame stream begins, and the new video data overwrites the former video data.
To display the Video Statistics screen for information about the latest video stream, follow these steps:
