ENUM

This IVR diagram sample illustrates how ENUM works. This IVR diagram sample was designed on the base of the Wikimedia Commons file: Ejemplo ENUM.jpg. [commons.wikimedia.org/wiki/File:Ejemplo_ENUM.jpg] "Being able to dial telephone numbers the way customers have come to expect is considered crucial for the convergence of classic telephone service (PSTN) and Internet telephony (Voice over IP, VoIP), and for the development of new IP multimedia services. The problem of a single universal personal identifier for multiple communication services can be solved with different approaches. One simple approach is the Electronic Number Mapping System (ENUM), developed by the IETF, using existing E.164 telephone numbers, protocols and infrastructure to indirectly access different services available under a single personal identifier. ENUM also permits connecting the IP world to the telephone system in a seamless manner." [Telephone number mapping.
