Mean Opinion Score (MOS) is calculated using an industry standard formula from data contained in the RTCP stream and Trace Route.

The data included in the formula are Packet loss, Latency, Jitter and Codec.


The MOS provides a numeric indication of the perceived quality of received voice:

                                  Good:  4.0 <

          Some Users satisfied:  3.6 - 4.0

      Many Users dissatisfied:  3.1 - 3.6

 Nearly all users dissatisfied:  2.6 - 3.1

             Not recommended:  1.0 - 2.6



The Mean Opinion Score (MOS) report shows a scatter plot of MOS stream distribution for selected equipment over a selected time period.

The csv export contains all the raw data per five minute interval for the period selected,
