Defining restriction filters 361
Programming Operations Guide
To delete an override: Select the override you want to delete, and then click on the Delete button at
the top of the column. If you want to delete all overrides for that restriction, click the Delete All
button.
Restriction filter examples
Line and set restrictions are shown in the following figures.
In the first figure, below, a caller using line 001 could only dial long-distance numbers to area
codes 212 and 718. A caller using line 003 could not dial any long-distance numbers. A caller
using line 005 could dial long-distance numbers to area codes 212, 718, and 415.
TIPS: To restrict dialing from outside the system (once a caller gains remote access), apply
restriction filters to incoming external lines (as remote restrictions).
