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.
