The quality of service dashboard allows you to see the overall quality of voice calls and view data for specific locations, queues, agents, or engagements. 

The dashboard uses Mean Opinion Score (MOS) as the main measurement to report on voice quality. 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 directly into a person's ear.

The 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.
