Dialling an exchange access prefix
The allocation of prefixes to access types is set out in the numbering plan, where
the prefixes can be configured (see
"Numbering Plan Identifiers", page 15
).
Exchange access prefixes are used to dial the following access types:
•
Exchange access, Business:
The call is routed via the route configured for the user.
The call charges are logged under Business on the user counter (among others)
(for more information on call charge allocation see
•
Exchange access, Private:
The call is routed via the route configured for the user.
The call charges are logged under Private on the user counter (among others).
•
Cost centre selection:
The call is routed via the route configured for the user.
The call charges are logged (among others) on the counter for the selected cost
centre.
•
Route selection:
The call is routed via the route selected by means of a prefix.
The call charges are logged under Business on the user counter (among others).
Dialling an abbreviated dialling Number
With an abbreviated dialling number dials the stored phone number. The phone
number must have an exchange access prefix.
The digit barring facilities are bypassed. If the call destination for an abbreviated di-
alling is to be barred using digit barring, the abbreviated dialling number must be
entered in the internal digit barring.
The call is routed via the user’s route, provided the stored phone number does not
already have a prefix for exchange access with route selection.
The call charges are logged in accordance with the user configuration, provided
the stored number does not already have an exchange access prefix that regulates
call charge logging (e.g.
Exchange access, Private
).
A name can be stored with each abbreviated dialling number, thereby also ena-
bling name dialling.
