ABSTRACT:
In a telephone communications system an Advanced Intelligent Network (AIN) platform is used to complete or block incoming calls to a subscriber in accordance with a threshold stored in the ISCP call processing record (CPR). The CPR contains a table of information that is customized in accordance with the options selected by the subscriber or simply may contain a threshold number that is decremented each time a call is completed. Incoming calls subsequent to decrementation to zero may be blocked, may require payment by the caller, or may be billed at a different rate. Decrementation may take place simply at a rate of one unit per completed call or at different rates in dependence upon calling area codes or locations. The CPR table may include a list of directory numbers against which individual threshold settings may be applied, while a generic threshold may be set for all other callers.
