ABSTRACT:
A method and system are provided for playing an advertisement to a telephone subscriber prior to call completion in a telecommunications network. A subscriber telephone line is provisioned to provide an advertisement. A switch in the telecommunications network detects an off-hook condition at the subscriber's telephone and interprets the digits of the telephone number of a called party dialed by the subscriber. The switch then retrieves an advertisement and plays the advertisement to the subscriber instead of generating a ringing tone prior to call completion. The switch may also play the advertisement instead of a dial tone. The advertisement may be stored in an advertisement module in the switch or in a network component in the telecommunications network. The period for playing the advertisement may be extended by delaying call processing at the network component. Once the advertisement begins playing, the subscriber may terminate the advertisement by depressing a key on a telephone keypad. The switches and network components in the telecommunications network may be advanced intelligent network (AIN) components.
