ABSTRACT:
An apparatus and method is disclosed for performing policing functions for specialized telephone services, and for mitigating fraudulent usage of such services in ubiquitous telephone networks that carry voice, facsimile or voice-band-data traffic. Signal processing is used to determine the properties of traffic present on a channel at a given point in time, and actions are conditionally imposed based on such traffic properties. A first embodiment of the invention can be applied to prevent fraudulent use of telephone services through suppression of an answer supervision response. A second embodiment of the invention can also be applied for regulation of access to specialized telephone services which depend on the manner of customers' use of such services.
