Calling Restrictions
Outward and toll restriction do not work with tie trunks or with T1 lines emulating
tie trunks which are set to tie-PBX. Automatic Route Selection or pool dial-out
codes should be used to restrict these types of line/trunks.
Because calling restrictions apply to extensions used to initiate a transfer to an
outside number, a user with a restricted extension can circumvent restrictions by
asking an operator with an unrestricted console to connect an outside call.
When a marked System Speed Dial code is used to dial a number, the System
Speed Dial number overrides calling restrictions (such as outward or toll
restrictions).
If Centrex service is used, any calling restrictions for the extension must be
programmed by the telephone company at the central office.

Feature Interactions

Allowed/
Disallowed Lists
When used with calling restrictions, Allowed Lists can permit the dialing of
specific numbers (such as emergency numbers) from an outward- or
toll-restricted extension.
Disallowed Lists can prevent the dialing of specific numbers from an
unrestricted or toll-restricted extension.
A Disallowed List takes precedence over an Allowed List.
Auto Dial
A user with a restricted extension cannot dial a restricted number
(outward or toll) by using an Auto Dial button unless the number is on the
Allowed List for that extension.
Automatic Route
Selection
ARS does not allow users to avoid calling restrictions. The system checks
for outward or toll restrictions assigned to the extension before it selects
the best route for making the call. If the ARS FRL assigned to the
extension restricts use of the route, a user hears an error tone and the call
does not go through. Because FRL assignment determines pools
selected in each route, a user may be allowed to select a pool using ARS
even if the extension is restricted from the pool dial-out code.
