Monitoring is enabled/disabled — monitoring current status. The Enable/Disable button can be used to
control the monitor's status.
When monitoring is enabled, calls already established will not be displayed, only new calls will be
displayed.
There are two monitoring tables in the menu. The left table contains general information on all active ses-
sions.
In the field "Rows in the table to show", the number of entries to be displayed on the page is specified. The
table on the right contains the current page number and the total number of pages. To navigate between pages,
the arrows under the table are used. A single arrow is for moving to the next/previous page, a double one is to
display the first/the last page.
