If charge information is sent to an ISDN connection, the resulting connection charges can be limited quite easily. For example, in its default state, a maximum of 830 charge units may be used in six days. The router will not permit the establishment of any further connections once this limit has been reached.
Note: The best way to use the router's call charge monitoring function
is if you have “call charge information enabled during
the connection” to the ISDN network (i.e.
AOCD). If necessary, subscribe to this facility from your telecommunications
carrier. Charge monitoring with the “Charge information after
connection“ feature is also possible in principle, but in this case
continuous connections may not be detected!
Note: If you have enabled least-cost routing
on the router modules, connections may be established to providers who
do not transmit any charge information!
