View call history
The call history (call journal/log) is stored as a sequence of files named divalog,divalog.1...divalog.N, where N is
the integer number in the /var/log directory. The divalog.N file contains the oldest trace information while the
divalog file contains the latest (current) information about the call activities.
You can use the call history viewer to decode the divalog file (call time, duration, type, speed) and view this
information without downloading the call history file to your local machine.
To download call history files, click Download. You will receive a text file that displays the various components
of the call history information separated by commas. The first line of the file contains the description of the
components.

Statistics Viewer analyzes the call history files found in the /var/log directory and creates
various statistics based on these files. The statistics show the total number of calls related to various periods of
time, the ratio of incoming and outgoing calls, the ratio of call types, call duration charts, a peak board load
chart, etc.
The statistic information is presented in a graphical format (jpeg) and can be used to analyze the system load
and reliability.
If you want to create your own statistics, download the call history files in the call history viewer and apply your
own spread-sheet application.
