Title: IETF Liaison Statement to SG-2 on EUM RFCs publication
Received: 7 May 2004

Dear Colleagues of ITU Study Group 2,

The IETF wishes to announce the publication of

      RFC 3761, The E.164 to Uniform Resource Identifiers (URI)
                          Dynamic Delegation Discovery System (DDDS) Application (ENUM)

This is the completed work of the ENUM Working Group on its
replacement for RFC 2916. At the same time, the IETF has published
the first two ENUM service registrations, RFCs 3762 and 3764, for H.323
and SIP respectively.

With best wishes,

Allison Mankin
Jon Peterson

This document discusses the use of the Domain Name System (DNS) for
storage of E.164 numbers. More specifically, how DNS can be used for
identifying available services connected to one E.164 number. It
specifically obsoletes RFC 2916 to bring it in line with the Dynamic
Delegation Discovery System (DDDS) Application specification found in
the document series specified in RFC 3401. It is very important to
note that it is impossible to read and understand this document
without reading the documents discussed in RFC 3401.

This document is a product of the Telephone Number Mapping (ENUM)
Working Group of the IETF.

This is now a Proposed Standard Protocol.

The H.323 specification defines a means for building multimedia
communication services over an arbitrary Packet Based Network,
including the Internet. This document registers a Telephone Number
Mapping (ENUM) service for H.323 according to specifications and
guidelines in RFC 3761.
