Viewing the Zoom Phone Quality of Service dashboard

In the Quality of Service dashboard, you can see how voice calls are being performed across all extensions (phone users, common area phones, call queues, car receptionists or Zoom Rooms).

MOS is the main voice quality indicator used in the dashboard. Based on a scale of 1 to 5, MOS measures voice quality. An unacceptable voice quality score is 1 for all users. The best voice quality is 5; this is equivalent to speaking directly into a person’s ear.

The dashboard categorizes calls based on MOS 3.5. A high MOS indicates good quality, while a low MOS indicates poor quality.
