At the ENUM introductory phase, a problem occurs when a called subscriber is not registered in the ENUM directory listing. In such a situation, a calling subscriber can initiate the ENUM request but it receives an error message only since no inscription exists in the ENUM registration with respect to said FQDN. The aim of said invention is to shorten said introductory phase. According to the invention, the subscriber called according to the ENUM request, is thereby informed about possibilities offered by the ENUM system in the case when the DNS registration is not available.
Lors de la phase d'introduction du système ENUM, un problème survient lorsque l'abonné appelé n'est pas inscrit dans le système ENUM. Dans cette situation, l'abonné appelant peut lancer une demande ENUM, mais il ne reçoit qu'un message d'erreur étant donné qu'aucune inscription n'existe dans le système ENUM relativement à ce FQDN. L'objectif de l'invention est de raccourcir la phase d'introduction susmentionnée. Selon l'invention, un abonné appelé d'après la demande ENUM est ainsi informé des possibilités offertes par le système ENUM en cas d'absence d'inscription DNS.
