A method for a stored program control system to deliver a complaint to a third party regarding a calling party, following termination of a call and a system for preparing and delivering a report of an unwanted call to a reporting authority following the call's completion are disclosed. The call from a called party destined for a calling party. The system comprises a telephone set, smart phone, or other communications phone or device capable of delivering voice and signalling data (102, 104); a switching element (106, 108); a data register (114) for storing only a called party's most recent calling party number and in communication with the switching element; and a third party node for receiving reports of an unwanted call. The node includes a processor adapted to receive and decode network SS7 signalling messages and receive SS7 messages directed to it from a switching element. The switching element includes 1) receiver and delivery components capable of respectively receiving and delivering voice and signalling data, 2) a SS7 message encoder and a SS7 message delivery engine, and 3) programmed instructions to accept, upon completion of a call, a particular customer-generated DTMF signalling code with indication of a complaint and in response thereto preparing and delivering a network SS7 signalling message. The message is directed to the third party node and including data from the register and the indication of the reason for the unwanted call and the third party node analyses a list of called party numbers, determines if the called party number is on the list, and updates the list based on the call and the analysis. The indicator indicates that the complaint is one of a do-not-call violation or perceived harassment.
