The Audio Call Quality page provides quality ratings that help you track audio-only call quality, systemwide. MOS values are graphed over an hourly scale showing the percentage of all VoIP calls on the network that were rated Normal, Degraded, or Excessive. On the chart, a secondary axis indicates the number of call minutes that contributed to the ratings.
By default, VoIP call activity to and from all groups and all Locations is graphed, using colors to show quality ratings.
You can use the MOS Type field to filter the page by MOS or Network MOS.
Call minutes are graphed with a line graph to show the number of observations for the Call Quality bar chart.
