发明名称 COMPUTER-BASED METHOD AND APPARATUS FOR CONTROLLING, MONITORING, RECORDING AND REPORTING TELEPHONE ACCESS
摘要 A method and apparatus for managing institutional telephone activity utilizes a computer control unit to control a trunk management unit, which connects institutional telephones to outside telephone lines. The computer control unit contains a database for storing the calling privileges and restrictions of institutional users and for recording calling transactions made by the users. The computer control unit implements a prospective call screening feature whereby outside recipients of undesired calls from the institution may enter a code that directs the computer control unit to prohibit similar calls in the future.
