Description

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.

L'invention est un dispositif servant à bloquer l'établissement des communications téléphoniques où l'appelant est victime de fraude. Les appels destinés à certains code régionaux sont parfois exemptés de règlements similaires à ceux auxquels sont soumis les codes régionaux américains. Comme conséquence, les appelants doivent parfois assumer sans le savoir des frais de communication exorbitants (fréquemment de plusieurs dollars la minute). Dans la présente invention, une base de données conserve un enregistrement des numéros de téléphone suspects et les appels destinés aux codes régionaux suspects sont vérifiés pour voir s'ils sont destinés à un numéro de téléphone suspect. Si tel est le cas, l'appelant en est informé et peut se déconnecter avant l'établissement de la communication. Les appelants peuvent donc éviter des frais de communication exorbitants.
