Outward And Toll Restrictions; Allowed/Disallowed Lists - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Features

Outward and Toll Restrictions

Apply to: Lines/trunks, especially those used for remote access or for
outcalling by a voice messaging system (see "Voice Messaging
Systems," later in this chapter), excluding tie and emulated tie trunks
programmed as Tie-PBX for Hybrid/PBX mode extensions.
Use with: Allowed Lists to permit restricted users to make some calls. (Tagged
System Speed Dial codes or their corresponding tagged Directory
listings can also be used to make certain calls.) Can be used with
any other calling restrictions.
An extension, line/trunk, or remote access user's barrier code can be
programmed to prevent either all outside calls or to prevent outside toll calls
only. In Release 3.1 and later systems, ports assigned for use by voice
messaging systems (generic or integrated VMI ports) are assigned outward
restrictions by default. If a voice messaging system is allowed to call out (for
example, to send calls to a user's home office), the system manager should
remove these restrictions.
NOTE:
In Release 3.1 and later systems in Hybrid/PBX mode, remote access users are
automatically restricted from making outside calls using the system. See
"Facility Restriction Levels (FRLs)" below for more information.

Allowed/Disallowed Lists

Apply to: Extensions and remote access barrier codes
Use Allowed Lists to permit restricted users to make some calls. (Tagged
System Speed Dial codes or their corresponding marked Directory listings can
also be used to make certain calls.) Use Disallowed Lists to provide some
protection from toll abuse when no other restrictions are applied.
Allowed/Disallowed Lists can be used with any other calling restrictions. This
feature provides flexibility by allowing users whose phones are restricted to call
specific numbers related to their business activities, as well as emergency
numbers.
