摘要: 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.
