tElephone NUmber Mapping (ENUM)

ENUM is a function for mapping E.164 numbers into Uniform Resource Identifiers (URIs) corresponding to communication applications associated with those numbers. ENUM utilizes the protocol developed by the Internet Engineering Task Force (IETF), specified in RFC 3761 that first transforms E.164 numbers into ENUM domain names and then uses the DNS-based architecture to access records from which the URIs are derived.
