Mean Opinion Score (MOS)

The QoS dashboard uses Mean Opinion Score (MOS) as the main measurement to report on voice calls. MOS measures voice quality on a scale of 1 to 5. A score of 1 indicates unacceptable voice quality for all users. A score of 5 is the best voice quality, equivalent to speaking directing into a person's ear.

The QoS dashboard uses a MOS of 3.5 as a general baseline to categorize calls. A MOS greater than or equal to 3.5 means good quality, while below 3.5 means poor quality.
