Abstract

Automatic Customer Callback (ACC) functionality is implemented directly into service logic of an Advanced Intelligent Network (AIN). The Advanced Intelligent Network includes a Central Office Switch (COS) which is provided in electrical communication with Service Control Point (SCP), at least one calling party, and at least one called party. The AIN components preferably communicate with one another through Transaction Capability Application Part (TCAP) signaling protocol and are directed for use in an AIN 0.2 network. An adjunct processor such as an Intelligent Peripheral (IP) is also provided in electrical communication with the COS. In operation, digits dialed by the calling party (those corresponding to the telephone number of the called party) are collected as well as the calling party telephone number. If the called party line is busy, then the calling party activates the Automatic Customer Callback (ACC) service, the subscriber's telephone line will be monitored to detect an idle condition. Once this condition is detected, a call may be originated from the adjunct processor to the subscriber whereupon a message may be played for receipt by the subscriber advising the same of the need to call back the calling party who has activated the ACC service. In an alternative embodiment, a three-way call is automatically originated from the adjunct processor to the subscriber and the calling party where, following completion of the call, the adjunct processor will disconnect itself.
