Exchange Line Authorisation, Call
Deblocker and Call Restrictor
The exchange line authorisation determines which phone number types can
be dialled by a subscriber (e.g., phone numbers in the local phone network).
Call deblockers can be added to the exchange line authorisations to expand
dialling options with additions of a certain supply of numbers (phone
numbers for specific connections or specific prefixes, released numbers).
Since call deblockers have a higher priority than call restrictors, they can be
used to release restricted numbers or parts of them.
In order to restrict exchange line authorisation, the phone numbers that
should not to be dialled can be put in call restrictors (restricted numbers).
There are several ways to do this. In general, phone numbers are restricted
that begin with a certain digit sequence and that should not be accessible to
every subscriber due to its higher charge tariffs, e.g., 0900 phone numbers.
Normally, the first 4 to 5 digits indicate the phone service that cause such
high charges.
If an attempt is made to dial a restricted phone number, only a busy signal
is heard. If the restricted numbers are not enabled (meaning "not
restricted"), restriction via the configured exchange line authorisation is still
possible.
Proceed as follows for configuration:
•
Creating the call deblocker and restrictor (outgoing).
