ABSTRACT:
A method and system directed for use in an Advanced Intelligent Network (AIN) for detecting and processing calls from a calling party to a subscribing called party wherein the display of calling party ID information has been inhibited. The Advanced Intelligent Network includes at least one Service Switching Point (SSP) in electrical communication with a Service Control Point (SCP) or Adjunct Processor (AP) via an appropriate signaling link and having corresponding service logic. The system and method are operative to detect an AIN termination attempt trigger at the SSP, suspend normal call processing, and generate an AIN termination attempt message at the SSP for receipt by the SCP/AP requesting further call processing instructions. If it is determined that calling party ID information has been inhibited, a response message is generated at the SCP/AP for receipt by the SSP instructing the SSP to intercept the call, play a selected terminating announcement or request the calling party to display its ID information so as to perform further call processing.
