ABSTRACT:
An arrangement for inhibiting the completion on defrauding calls. Calls to certain area codes are sometimes not subject to the kinds of regulations characteristic of U.S. based area codes. The result is that callers are charged an exorbitant fee (frequently several dollars per minute) without realizing that they are incurring such charges. In accordance with applicant's invention, a data base maintains a record of suspected telephone numbers and calls to the suspected area codes are checked to see if the call is to one of the suspected numbers. If so, the caller is warned and can disconnect before the call is completed. Advantageously, possibly for the payment of the fee, callers are saved from making calls with exorbitant charges.
