Calling Restrictions
Description
Designated voice and data terminals can be restricted from making certain types of calls. Available
restrictions are:
Outward Restriction
Toll Restriction
Facility Access Restriction
ARS Restrictions
Public Station Restrictions
International Restrictions.
Interexchange Carrier (IXC) Restrictions
Note: Each of these restrictions is voice terminal oriented, not PDC oriented.
Outward Restriction:
When outward restricted, a station will be unable to place any outside calls. The station will be able
to answer incoming calls and place and receive inside calls. A station that is outward restricted will
be unable to use Automatic Route Selection to place external calls except to the emergency
numbers.
Toll Restriction:
Allows calls by restricted terminals to be made based on as many as the first six digits of the
number called (after the facility access code). Toll restricted stations can make outgoing calls only
to those numbers that are on the Toll Call Allowed (TCA) Lists to which they have access. TCA
entries must be in the form AAA or NAA-XXX (exactly three or six characters). The system
administrator can establish up to 5 individual lists. A list can contain from 1 to 164 entries, provided
that the total of all five lists does not exceed 164. One character
“.” can be specified as a wild card
character in place of the last 1, 2, 3, 4, or 5 digits (e.g., “NA.”, “N..”, “N.....”, etc.). When this
character is used, any digit in the dialed number appearing in that position is acceptable. Those
stations assigned Toll Restriction Class 1 have access to all five TCA Lists; Class 2 stations, just
lists 2 through 5; Class 3 stations, just list 3 through 5; Class 4 stations, just list 4 through 5; and
Class 5 stations, just list 5. To allow calls within a customer’s local area, individual office codes are
entered; this allows the customer to restrict toll calls within the local calling area. NAA-AAA entries
allow specific office codes to be called within an area. Note: NAA-only entries are not permitted
(use NAA-...).
Note that stations that are toll restricted are only toll restricted on CO trunks (type 701 and 801),
when they use the ARS feature, or when a PBX/Centrex trunk and the PBX/Centrex access digit is
dialed. They will not be toll restricted when they dial access (or button access) any other type of
trunk (e.g., FX, WATS, or Tie trunks).
