VoIP Summary
The VoIP Summary tab allows you to view the
pass/fail status and measurement details of the
different parameters. If a measured value is out the
thresholds configured in the VoIP Call setup, or if the
WAN connection was not completed successfully, the
VoIP Summary page will display a fail status.
MOS displays values for both the average and
current Mean Opinion Score, which provides a
relative measurement of VoIP call quality.
R-Factor displays values for both the average and
current R-Factor score which is a VoIP
transmission quality rating derived from multiple
VoIP metrics, including latency, jitter, and loss.
Latency displays the average, current, and maximum time delay
experienced (in ms) to deliver VoIP packets.
Jitter displays the average, current, and maximum variation (in ms) in
the packet transit delay of received VoIP packets.
