Title (EN) SYSTEM AND METHOD FOR PREVENTING ROBOCALL VOICEMAIL DEPOSIT
(FR) SYSTÈME ET PROCÉDÉ POUR EMPÊCHER UN APPEL AUTOMATISÉ DE LAISSER UN MESSAGE VOCAL
Abstract:
(EN) Systems and methods for preventing a robocall from leaving a voicemail are described. When an incoming call without a history information header (HIH) destined for a subscriber is detected, the incoming call is prevented from leaving a voicemail if the subscriber does not answer the incoming call. If the incoming call has the HIH, additional determination process based on a visited network address of the subscriber is performed to determine whether the incoming call is to be prevented from leaving a voicemail.
(FR) La présente invention concerne des systèmes et des procédés qui permettent d'empêcher un appel automatisé de laisser un message vocal. Lorsqu'un appel entrant sans en-tête d'informations d'historique (HIH) destiné à un abonné est détecté, l'appel entrant n’est pas autorisé à laisser un message vocal si l'abonné ne répond pas à l'appel entrant. Si l'appel entrant dispose d’un HIH, un processus de détermination supplémentaire fondé sur une adresse réseau visitée de l'abonné est effectué pour déterminer si l'appel entrant doit ou ne doit pas être autorisé à laisser un message vocal.
