Call Quality
This pane provides information about the quality of calls on the network over the selected time period. Select the type of
call quality information displayed on this pane by clicking the Trend, Distribution or APs links in the upper right
corner of the call quality chart.
The Trend chart shows the number of calls with good, fair, or poor client health over the selected time period. The
Distribution graph shows the relative proportions of calls with each quality type, and the APs chart shows information
about APs that supported poor quality calls. You can also hover your mouse over the Trend or Distribution charts to
view details about the highlighted section of that chart.
Quality Correlation
These graphs display the correlation between the call quality and the client health of every UCC call. The client health
metric displayed in these charts is the efficiency at which that AP transmits downstream traffic to a particular client. This
value is determined by comparing the amount of time the AP spends transmitting call data to a client to the amount of
time that would be required under ideal conditions, that is, at the maximum Rx rate supported by client, with no data
retries. A client health metric of 100% means the actual airtime the AP spends transmitting data is equal to the ideal
amount of time required to send data to the client. A client health metric of 50% means the AP is taking twice as long as
is ideal, or is sending one extra transmission to that client for every packet. A metric of 25% means the AP is taking four
times longer than the ideal transmission time, or is sending 3 extra transmissions to that client for every packet.
Select the type of quality correlation information displayed on this pane by clicking the Trend or Scaterplot links in
the upper right corner of the quality correlation chart.The Trend quality correlation chart shows the number of calls with
good, fair, or poor client health over the selected time period, while the Scatterplot chart shows the call quality and
client health of each individual call. You can also hover your mouse over the Trend or Scatterplot charts to view details
about the highlighted section of that chart.
Call Volume
The Call Volume Trend graph and table displays the number of calls made during the selected time period using a
specific UCC application type, such as SIP, Lync, SCCP, H.323, NOE, SVP, VOCERA, or FaceTime. You can hover
your mouse over this chart to view details about the highlighted section. The Call Volume APs graph shows the names
of the APs that supported these calls. Select the type of call volume information displayed on this pane by clicking the
Trend or APs links in the upper right corner of the call volume chart.
Devices
These graphs display information about the calls made by different device types, such as Windows 7, Mac OS X, iPhone,
or Android devices. The Devices Trend graph show the numbers of calls by each platform typeover the selected time
period. The Distribution chart shows the relative proportion of calls that originated form each device type, and the
Devices Quality graph shows the numbers of calls at each quality level made by each device type. Hover your mouse
over the Trend or Distribution charts to view details about the highlighted section of that chart.
