Y-axis
The Y-axis on the Detailed Reports line graphs is the vertical area of the report, covering the top
to the bottom of the graph. The top of the Y-axis represents the upper levels for each of the QoS
parameters and the bottom of the Y-axis represents the lower levels. You can point your mouse
at the samples on the line graph and the exact time and QoS value will display. For more detailed
information, see the topic on About Detailed Reports and/or Interpreting Detailed Reports.
Different Scales for Each QoS Parameter
The QoS parameters have different values. To represent each parameter on the same report, the
Y-axis has a different scale that suits each QoS parameter. These scales are shown on the Y-
axis in their respective colors.
X-axis
The X-axis on the Detailed Reports represents the date range. It is the horizontal area of the line
graph, from the left to the right of the report. The start of the date range begins from the left of the
horizontal axis and continues until the end of the date range on the far right side.
Alter the Date Range to Show More Detail
You can alter the date range to a shorter date or longer date period to see more or less detail.
Gateway
The Results List will display one or more phone numbers next to the Gateway endpoint type.
These phone numbers are the phone numbers for which that the Gateway is acting as an
intermediary. Therefore, the phone number of the Gateway can change and can be multiple
phone numbers. The Results List will separate endpoints involved in a session with a comma (,).
Conferenced calls are separated by a colon (:).
