Calling Party Number Restriction
With Calling Party Number (CPN) Restriction, you can administer individual
phones to restrict sending CPN information on outgoing calls (per call restriction).
Also, phone users can use a phone button or a feature access code (FAC) to restrict
CPN information on individual outgoing calls (per line restriction). CPN
Restriction works on any trunk that supports MFC signaling.
Per Line CPN Restriction overrides any outgoing trunk group CPN
administration. Per Call CPN Restriction overrides any Per Line CPN Restriction
for the phone, and it also overrides any Trunk Group administration for sending
the calling number. For a tandemed ISDN call, only the Tandem Trunk Group’s
“sending calling number” administration applies.
Interactions
CPN Restriction is not supported on:
■ local switch station-to-station calls
■ calls originated from attendant console or data module
■ DCS calls (DCS CPN information is not affected by CPN Restriction)
■ Uniform Dial Plan (UDP) calls
■ Trunk Access Code (TAC) calls where the Per Line CPN Restriction field
on the * screen is
y or r, or when the Per Call CPN Restriction FAC is
dialed before the TAC
■ non-ISDN calls that must be tandemed
■ Per Call CPN Restriction over Adjunct Switch Application Interface
(ASAI) and CTI interfaces
