ENUM: E164 NUmber Mapping
Electronic Numbering (ENUM or Enum), also refered to as "E164 NUmber Mapping", is a suite of protocols to unify the telephone system with the Internet by using E.164 addresses with Dynamic Delegation Discovery System (DDDS) and Domain Name System (DNS). ENUM is a standard adopted by the Internet Engineering Task Force (IETF) that uses the domain name system (DNS) to map telephone numbers to Web addresses or uniform resource locators (URL). The goal of the ENUM standard is to provide a single number to replace the multiple numbers and addresses for an individual's home phone, business phone, fax, cell phone, and e-mail.
