One Number, Many Devices
ITUís electronic numbering (ENUM) initiative promises to be one of its most high-profile developments, giving true convergence across different network types and devices. Simply put, ENUM will give users the ability to have calls to
a single number directed to a wide variety of devices ó including fax, e-mail, pager, mobile phone, SIP telephony address or website.
The development of ENUM has also demonstrated ITUís willingness to work with other standards bodies. The Internet Engineering Task Force (IETF) has also been key to the successful definition of the ENUM standard.
ENUMís development has been complicated. Not only have a disparate set of networks had to be joined, but many different regulatory regimes across the world have had to be consulted.
Analysts have predicted that ENUM will allow the introduction of a range of new services that may be key to the success of next- generation networks. For example, ENUM will allow a user to call a voice-enabled IP terminal from a
conventional telephone. It also means that a user can decide which device they want to deal with a call.
