What is ENUM

• ENUM is part of the convergence of Circuit
  Switched and Packet Networks
• ENUM is defined by the Internet Engineering Task
  Force (IETF) and translates an E164 number into
  Internet Domain Names RFC 2916- September 2000
• ENUM is about new service creation
• Allows the use of a traditional telephone number
  in the context of different communication media,
  e.g., e-mail, VoIP, and therefore could
  facilitate the penetration of new applications
  into the mass market easily
• Defines the use of Domain Name System (DNS)
  resource records to find optional
• E-mail addresses
• Voice over IP SIP / H.323 servers
• Voice Mail servers
• Fax Machines
• 
  Defined by US ENUM Forum

ENUM Benefits

• Facilitates terminating calls to IP based
  networks
• An important ingredient in the convergence of the
  PSTN, the Internet and other IP based networks
• ENUM is a directory infrastructure - ENUM by
  itself has no value
• Revenues will be driven by new value-added
  services and applications enabled by ENUM

7
ENUM Benefits

• End User
• Simplicity
• One Number addressing eliminates need to remember
  multiple, complex addresses
• Expand connectivity
• Calls to non-PSTN (i.e., IP) devices can be
  completed
• Service Provider
• New services revenues
• PSTN-IP Telephony
• Strategic
• Expand reach into the Internet
