Call routing

System functions and features as of R4.1
syd-0570/1.2 – R4.1 – 08.2016
• The lock function on the phone lock variants activates an internal and an external
digit barring.
• Digit barring facilities cannot be allocated to a PISN user.
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 configura-
tion
Example:
The digit barring is deactivated in the route configuration for route 1 and activated 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 barring will be
consulted.
• Calls via analogue network interfaces that are set to Behind communication server.
• Stored phone numbers of PISN users
• Stored call numbers of integrated mobile/external users
• Stored phone numbers of emergency and abbreviated dialling numbers, provided
the emergency or abbreviated dialling number is dialled.
• Stored phone numbers of abbreviated dialling numbers, provided they are dialled
using dialling-by-name.
Note:
If a function code used for operating a feature is stored under an abbreviated 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 allocated
digit barring.
Example:
• Basic function = All free
