CONSIDERATIONS
RELATED FEATURES
Call Restriction can also be used in combination with features such as Allowed
Lists and Automatic Route Selection to further reduce the costs of operating
your MERLIN II system.
● If call restrictions are too limiting, you can keep phones unrestricted but set
up Disallowed Lists to prevent calls from being made to certain numbers or
you can restrict phones but assign one or more Allowed List—numbers that
individuals may call beyond the established restrictions.
● Even though a phone is restricted in placing calls, the user can still receive all
types of incoming calls. Someone with a restricted phone can bridge onto
any call or conference call in progress.
● Allowed Lists
● Disallowed Lists
How to Administer
To restrict phones to local calls only, the system must be able to identify toll calls as people dial
them. Form 1A, System Form—Incoming Lines, shows which lines in your system, if any, do not
require a toll prefix (0 or 1) for long distance calls. If you have lines on which it is not necessary to
dial a toll prefix, you need to know which lines they are so you may correctly assign Call
Restrictions.
NOTE: If a toll prefix is required on all your lines, skip the first procedure below and go on to
the second procedure, “To administer call restrictions.”
To identify toll types for selected lines:
1 Enter administration mode by sliding the T/P switch to P.
2 Press Conference twice.
The administration menu appears.
3 Press [Lines], [TollType].
4 Press the line buttons until the lights show the appropriate code:
Steady green on = toll calls detected by toll prefix only
Green off = toll calls detected by area code or toll prefix
5 Press Conference to return to the main administration menu and go on to step 2 of the next
procedure.
