Abstract

The present invention provides a method and apparatus for determining whether a party initiating a telephone call is on a list of parties authorized by the called party. If the calling party is not on the list of authorized parties, a fee is charged to the calling party. All or a portion of this fee may be paid to the called party or may be applied to the called party's telephone service billing account to reduce the called party's telephone bill. Preferably, the present invention is implemented at the called party's central office, i.e., at the central office which services the called party. In accordance with common-channel signaling, commonly referred to as signaling system 7 (SS7), the calling party's telephone number and identity are received in the call signaling data transmitted to the central office which services the called party. Processing equipment located at the called party's central office is programmed to compare the calling party's identity and/or telephone number with a list of authorized identities and/or telephone numbers associated with the called party to determine whether the calling party is an authorized party.
