Restrictions
Restrictions prevent a user from making certain kinds of calls
from a telephone or from lines that are available at the
telephone. It also restricts some features.
When you are finished programming restriction settings for
one telephone, you can copy those settings to other telephones
by using
COPY
at the
Restrictions ˆ
display.
For ISDN PRI, all line restriction changes are applicable to all
lines.
For more information about copying set programming, see
Copying telephone programming on page 316.
Filters
Restriction filters group call restrictions and overrides in
packages that allow you to make restriction assignments to
lines and sets with just one package indicator.
In addition to restricting telephone numbers, you can prevent
people from entering dialing sequences used by the public
network to deliver special services and features. Some public
network features provide the caller with dial tone after they
have entered the special code, usually
£
or
•
, so users may
have an opportunity to bypass restrictions. To prevent this
from happening, you should create filters that block these
special codes.
You create a filter by defining the dialing sequences that are
denied.
