Bypassing the digit barring
Digit barring facilities are bypassed in the following cases:
• Deactivation of the external digit barring allocated to the user in the route con-
figuration
Example:
The digit barring is deactivated in the route configuration for route 1 and acti-
vated in the route configuration for route 2.
If a user with an allocated external digit barring sets up a call via route 1, the
digit barring will not be consulted; if he sets up the call via route 2, the digit bar-
ring will be consulted.
• Calls via analogue network interfaces that are set to
Behind communication
server
.
• Stored phone numbers of PISN users
• Stored phone numbers of integrated mobile phone users
• Stored phone numbers of emergency and abbreviated dialling numbers, pro-
vided the emergency or abbreviated dialling number is dialled.
• Stored phone numbers of abbreviated dialling numbers, provided they are di-
alled using dialling-by-name.
• The digit barring for external remote control cannot be bypassed. (This applies
only to internal users on their own communication server but not to PISN users
in a QSIG network.)
Note:
If a function code used for operating a feature is stored under an abbrevi-
ated dialling number, make sure the abbreviated dialling number is
barred in the digit barring for unauthorized internal users and that no
name is assigned to the abbreviated dialling number. In a QSIG network
this applies in particular to all PINXs that have entered the abbreviated
dialling number as PISN users in the numbering plan.
Setting up the digit barring
In a digit barring everything can in principle be enabled (
Basic function
=
enable all
)
or barred (
Basic function
=
bar all
).
Exceptions to the basic setup are entered in an enabled list or in a barring list.
Digit sequences that are not on the enabled or barring list are either enabled or
barred, depending on the basic setup.
A phone number is compared from left to right with the digit sequence of the allo-
cated digit barring.
