What is MOS?
MOS (mean opinion score) is a measure of the call quality. Historically, users would listen to calls and would report whether their experience was good or bad on a 5 point scale. Modern systems, such as the Exinda appliance, automate MOS testing taking into account network dependency conditions. The scores have the following meaning.
What is rFactor?
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.
