The Subscriber object dispatches a
qualityScoreChanged event when either the audio or
video quality score changes for the subscriber. The scores are a
heuristic value representing the expected subscriber experience.
The values are integers ranging from 1 to 5, with the values
corresponding to bad, poor, fair, good, and excellent.
