Enum Technology

ABSTRACT:

ENUM is a solution to the question of how network elements can find services on the Internet using only a telephone number, and how telephones, which have an input mechanism limited to twelve keys on a keypad, can be used to access Internet services. It will provide cost savings and revenue opportunities for both carriers and customers, and it will solve many of the interoperability problems faced by the Voice over IP (VoIP) industry.

ENUM at its most basic is the convergence of the Public Switched Telephone Network (PSTN) and Internet Protocol (IP) networks; it is the mapping of a telephone number from the PSTN to Internet functionalities. ENUM takes a complete, international telephone number and resolves it to a fully qualified domain name address using a Domain Name Service (DNS)-based architecture.
