The result is that callers are charged an exorbitant fee (frequentlyseveral dollars per minute) without realizing that they are incurring such charges. Inaccordance with applicant's invention, a data base maintains a record of suspectedtelephone numbers and calls to the suspected area codes are checked to see if the call isto one of the suspected numbers. If so, the caller is warned and can disconnect beforethe call is completed. Advantageously, possibly for the payment of the fee, callers aresaved from making calls with exorbitant charges.
