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.

REVIEW DRAFT - CISCO CONFIDENTIAL
Description
Version of the Cisco proprietary algorithm that is used to calculate MOS
LQK scores.
Total number of concealment frames divided by total number of speech
frames that were received from start of the voice stream.
Ratio of concealment frames to speech frames in preceding 3-second interval
of active speech. If using voice activity detection (VAD), a longer interval
might be required to accumulate 3 seconds of active speech.
Highest interval concealment ratio from start of the voice stream.
Number of seconds that have concealment events (lost frames) from the start
of the voice stream (includes severely concealed seconds).
Number of seconds that have more than 5 percent concealment events (lost
frames) from the start of the voice stream.
Estimate of the network latency, expressed in milliseconds. Represents a
running average of the round-trip delay, measured when RTCP receiver report
blocks are received.
