The call quality indicator () shows the quality of audio, video and screen sharing
connections during an active call (conference call or one-on-one call).
The indicator shows up to three bars:
Three bars: call quality is high and all values are within the expected
range.
Two bars: call quality is medium, some values are below the expected range.
One bar: call quality is low, several values are below the expected range or
packet loss is high.
No bars: call quality is poor, most indicators are below the expected range or
packet loss is very high.
