The Mean Opinion Score (MOS) feature is used to measure the voice quality on an extension. It ranges from 0 to 5, where 5 is the best quality. This is useful for monitoring the quality of the calls that occur on a particular extension. MOS is typically enabled on the web-based utility of the phone.
