R-Value >= 0 and < 60 :  Red


R-value / R-factor:

The parameters included in the computation of the R-Factor are fairly extensive, covering factors such as echo, background noise, signal loss, codec impairments and others. R-Factor is a technical version of the MOS score…whereas MOS score is subjective rating based what the end user hear. R-value uses technical data to come up with the number
