Press the display button to enter a
l
wild card character that
represents any digit in a sequence of numbers.

You may need filters for three different types of users:
Managers may require unrestricted dialing.
Secretaries may need to be limited to calling the West coast
office on line 03 only.
Clerks may need to be limited to calling specific area codes
and the West coast office.
Dialing filters are most commonly used to prevent unauthorized
long-distance calls, without restricting local calls. Dialing filters
restrict the numbers that an internal user can dial on external
lines.
If a line/set filter has been defined for the line selected at the
user’s telephone, it overrides any line filters or telephone filters
which might otherwise apply.
If no line/set filters have been defined, dialed digits are filtered
through (and may be rejected by either of) the telephone filter (if
defined) and the line filter (if defined).
