• The button Edit allows to edit already existing entries.
•With Delete an entry can be deleted. For safety reasons you must confirm
that you really want to delete the entry.
NOTE
Please consider that only numeric characters which are actually entered are
analyzed, i.e. if you only enter „130“, all participants with a calling number
which ends with „130“ are allowed to call the system.
The total character length of all entered telephone numbers must not be hig-
her than 127. With an average lenght of a telephone number of 12 characters
about 10 calling numbers can be entered.
For this functionality the calling numbers of the participants in the list needs
to be transmitted (CLIP
