Understanding the data displayed in an Application Performance VoIP report
The graph shows three series, representing the number of "Good", "Tolerable" and "Bad" calls over time. The table below the chart lists the worst quality inbound and outbound VoIP calls for the specified time period.
The meanings of the colors:
- Good (green) - MOS greater than 4.
- Tolerable (yellow) - MOS between 2 and 4.
- Bad (red) - MOS less than 2.
MOS, or Mean Opinion Score, is a measure of all quality. Historically, users would rate their call experience on a five point scale.
An Exinda Appliance automates MOS ratings, taking into account network dependency conditions. The scores have the following meanings.
5 - Perfect, like face-to-face conversations or radio reception.
4 - Fair, imperfections perceived, but the sound is clear. Cell phones calls are typically rated fair.
3 - Annoying.
2 - Very annoying, nearly impossible to communicate.
1 - Impossible to communicate.
rFactor is a measure of the call quality in IP networks taking into account network delay and impairments. rFactor ranges from 0 (extremely poor quality) to 100 (high quality). Any rFactor less than 50 is not acceptable.
