AT&T 4.1 Telephone User Manual


 
Outgoing Call Restriction (#401)
Description
This telephone option restricts calling on all lines at a specified extension. The
factory setting is that all extensions have no restriction, so change the setting
only for the extensions you want to restrict.
Related Features
Use Outgoing Call Prefix (#402) to indicate whether or not a user must dial
a 0 or 1 before the area code when making long distance calls. When
Outgoing Call Prefix is set to 1, a long distance call is one in which the first
digit is 0 or 1. When Outgoing Call Prefix is set to 2, a long distance call is
one in which the second digit is 0 or 1.
Do not restrict an extension assigned as an external hotline phone so as to
prevent the outside number from
-
being dialed. See Doorphone/Internal
Hotline Phone/External Hotline Phone (#604).
Considerations
Be aware that some local telephone company custom calling features,
consisting of * plus a designated feature code, return dial tone after
activating themselves. If your users access these features, the system will
not block a subsequent long distance call made by those users, regardless
of the Outgoing Call Restriction setting for their extension.
If the system is connected to a PBX or Centrex system and a dial-out code
(usually 9) is needed to place calls outside the PBX or Centrex system, the
system will not be able to prevent long distance calls for extensions
restricted to Local Only, since the PBX or Centrex system cannot distinguish
between long distance and local calls. If your PBX or Centrex system
includes dialing restrictions, use those instead of Outgoing Call Restriction
(#401). If you have PBX or Centrex dialing restrictions on a line and also
use Outgoing Call Restriction (#401), both the PBX or Centrex system
restriction and this restriction may apply.
While dialing restrictions are very effective, absolute protection against
misuse cannot be guaranteed. System phones give you more protection
against misuse than standard phones. Therefore, we strongly recommend
that you install system phones where restricting phone use is important.
Inside Only is useful for phones in reception areas or other public rooms
where you want to prevent anyone using the phone from making outside
calls. It is also useful for prohibiting calls from warehouse extensions, or
from extensions that should be used only for receiving orders.
