Abstract
ENUM creates many new market opportunities and raises several important policy issues related to the implementation and administration of the ENUM database and services. Recent World Telecommunications Policy Forum 2001 dealt with the emergence of ENUM as an important numbering issue of IP telephony. This paper prepares some important emerging issues of ENUM administration and policy by taking an empirical research approach from the bottom up. We will identify potential key ENUM services, and estimating the size of the service market opportunities created by the availability of PSTN-IP addressing and mapping mechanisms, particularly in the context of IP telephony. Also, we analyze the possible administrative models and relationship scenarios among different ENUM players such as Registry(ies), Registrars, Telephone Service Providers, ENUM Application Service Providers, etc. Then, we…
