Dialing Restrictions Summary
While procedures that restrict
dialing are very effective,
absolute protection against
misuse cannot be guaranteed.
PARTNER phones give more
protection than standard phones.
Therefore, we strongly
recommend that you install
PARTNER phones where
restricting phone use is
important.
No Outside Line Access
The PARTNER Plus system includes several ways to restrict dialing from
individual extensions. This appendix discusses the dialing restrictions and ways
to override the restrictions. The system programming procedures necessary to
set the restrictions are also included.
In general, you can restrict all outside dialing from an extension or allow outside
dialing with varying limitations. These limitations may be as simple as
preventing calls to a specific phone number through a Disallowed Phone
Number List. Or they may be as complex as combining Allowed Phone Number
Lists, Disallowed Phone Number Lists, and Outgoing Call Restrictions to allow a
user to call just the numbers he or she needs for business. All of the restrictions
work on a per extension basis so you can tailor the restrictions to your users.
This appendix is designed to give you information about the restrictions and how
they interact. As you decide on the restrictions to assign users, be careful not
to make them too tight or too loose. And remember, you can change them at
any time through system programming.
Three programming procedures prevent an extension from ever dialing out on a
specific line. Two of them work by not assigning the line (or lines) to the
extension. The third restricts the type of calls that can be placed on the line.
These restrictions cannot be overridden.
#301—Line Assignment. Using this procedure, you can selectively assign
lines to extensions. To prevent an extension from having access to a line,
unassign it.
#302—Line Use Restriction. Using this procedure, you can restrict the type
of calls allowed on a line assigned to an extension. A line can be
unrestricted (that is, any type of call is allowed), restricted to making
"outgoing calls only," restricted to receiving "incoming calls only," or
restricted to "no access. "
If you restrict a line on an extension to incoming calls only, the user cannot
select the line to dial out at all (even numbers on the Emergency Phone
Number List or Marked System Speed Dial numbers). If a line is unrestricted
or restricted to outgoing calls only, use the restrictions discussed in the rest
of this appendix to restrict dialing.
