Use the button, the display button, the dial pad,
and the display button to program the restrictions and
exceptions for each dialing filter.
For example
You may need filters for three different, types of users:
Managers may require unrestricted dialing.
Secretaries may need to be limited to calls on line 003 to the
West coast office only.
Clerks may need to be limited to calling specific area codes
and the West coast office.
Internal users
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).
External users
For a remote user,.who has dialed into on an
auto-answer line (or a DID line), and passed through any
security, there are no restrictions on the numbers the user can
dial.
For remote users trying to tandem through the system,
the Line filters and Remote filters assigned in Line abilities apply.
For a remote user entering the system through DISA, the filters
and Remote access packages associated with their COS
password replace the Remote filter, the Line filter, and the
Remote access package assigned to the incoming line.
