3. SSW – 2 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

6. SSW – 5 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. SSW – 6 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

8.
