The ENUM working group has defined a DNS-based architecture and 
  [RFC 3761] by which an E.164 number, as defined in ITU Recommendation
  E.164, can be expressed as a Fully Qualified Domain Name in a specific
  Internet Infrastructure domain defined for this purpose (
  E.164 numbers are globally unique, language independent identifiers for
  resources on Public Telecommunication Networks that can support many
  different services and protocols. There is an emerging desire for
  network operators to utilize aspects of RFC 3761 to discover points of
  interconnection necessary to terminate communications sessions
  identified by a E164 number,in addition to identifying end point
  protocols and services.
  Working Group Revised Goals and Scope:
  1. The working group will update RFC 3761 and advance to Draft 
  2. The working group will examine and document the use of RFC 3761 to
  facilitate network interconnection for services using E.164 addressing.
  The working group will coordinate its activities with other IETF 
  groups, existing or to be chartered, that are investigating elements of
  peering and or interconnection for VoIP or other services that 
  use E.164 addressing.
  3. The working group will continue examine and document various aspects
  of ENUM administrative and /or operational procedures irrespective of
  whether domain is used.
  4. The working group will also examine the use of RFC 3761 technology
  for storing and delivering other information about services addressed 
  E.164 numbers, for example PSTN call routing and signaling data.
  5. The Working Group will continue to maintain appropriate contact and
  liaison with other standards bodies and groups, specifically ITU-T SG2,
  to provide technical or educational information and address, as needed,
  issues related to the use of the E.164 numbering plan for services on 
  networks. In addition the Working Group will continue to encourage the
  exchange of technical information within the emerging global ENUM
  community as well as documentation on practical experiences with
  implementations, alternate technology uses and the administration and
  provisioning of RFC 3761.
  6. As described in RFC 3761, the IETF documents and registers the
  Enumservices. While extant, it is the ENUM working group that performs
  the technical review and development of the Enumservices for the
  Internet community. The working group determines whether to advance 
  and how to progress them technically. Coordination with other WGs will
  be taken into account on these.
  Other than Enumservices, all proposed deliverables of the working group
  will be discussed with and approved by the Area Directors, who may
  require wider review due to the broad impact of the subject.
