Patent

CA 2134254

An adjunct processor (16) sends an end-of-address indication, such as a pound sign, along with the address, such as an extension number, to which a call is to be transferred, to a switching system (12, 14). The sent end-of-address indication causes the switching system to not accept further addressing information from the caller (10), thus preventing the caller from modifying the sent address and effecting the transfer of the call to an address different from the sent address, such as a long-distance telephone number. Perpetration of adjunct-assisted toll fraud is prevented thereby.

Un processeur auxiliaire (16) envoie à un système de commutation (12, 14) une indication de fin d'adresse, par exemple un signe numéro, conjointement avec l'adresse, par exemple le numéro d'un poste auquel un appel doit être transféré. L'indication de fin d'adresse envoyée empêche le système de commutation d'accepter de l'appelant (10) toute autre information d'adressage, ce qui empêche l'appelant de modifier l'adresse envoyée et d'effectuer le transfert de l'appel à une adresse différente de l'adresse d'envoi, par exemple à un numéro de téléphone interurbain. On empêche ainsi les fraudes d'interurbain assistées par processeur auxiliaire.
