Telephone Number Mapping (enum) ------------------------------- Charter Last Modified: 2009-03-30 Current Status: Active Working Group Chair(s): Richard Shockey Patrik Faltstrom Real-time Applications and Infrastructure Area Director(s): Robert Sparks Cullen Jennings Real-time Applications and Infrastructure Area Advisor: Cullen Jennings Secretary(ies): Alexander Mayrhofer Mailing Lists: General Discussion:enum@ietf.org To Subscribe: enum-request@ietf.org In Body: subscribe Archive: http://www.ietf.org/mail-archive/web/enum/index.html Description of Working Group: The ENUM working group has defined a DNS-based architecture and protocol [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 (e164.arpa). Background: 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 Standard. 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 working groups, existing or to be chartered, that are investigating elements of peering and or interconnection for VoIP or other services that typically 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 e164.arpa 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 by 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 IP 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 them 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.
