A Call Filter System (CFS): (1) logically interfaces between a public telephone network and business customer premises equipment; (2) automatically processes incoming and outgoing calls which are amenable to such intervention; and (3) enlists the aid of human intervention on calls requiring such intervention. The CFS includes a network line interface (NLI) for receiving calls from and placing calls to the public telephone network; a premises line interface (PLI) for receiving calls from and placing calls to the business customer premises equipment; a voice processing means (VPM) which is switchably interconnected to the NLI and/or the PLI for translating audio signals transmitted thereto from the NLI or PLI and for transmitting audio signals to the NLI or PLI; a connection and switching means (CSM) for connecting and switching the NLI to either the PLI or VPM and for connecting and switching the PLI to either the NLI or VPM; and a controller for directing the activities of the NLI, PLI, VPM and CSM to automatically process incoming calls to and outgoing calls from the CFS.
