[Enum] H.323 enumservice registration ID

[Richard Shockey <[e-mail]>]

This document has gone in the queue...I'm making it available early for 
your review ...

I'll be adding Orit and this Draft to the ENUM WG agenda as well  along 
with Jon Peterson who has also posted a SIP enumservice registration document.

many many thanks to Orit for getting this ready in time for Atlanta

Abstract

    The H.323 specification [2] defines a means for building multimedia
    communication services over an arbitrary Packet Based Network,
    including the Internet. This document registers an ENUM service for
    H.323 according to specifications and guidelines in RFC2916bis [3].

                   ENUM Service Registration for H.323 URL

Introduction

    The H.323 specification [2] defines a means for building multimedia
    communication services over an arbitrary Packet Based Network,
    including the Internet. When H.323 is used in the context of the
    Internet, it would be useful to take advantages of such services as
    domain name system (DNS) and ENUM in order to help facilitate the
    completion of multimedia calls.

    This document registers an ENUM service for H.323 according to
    specifications and guidelines in RFC2916bis [3].

ENUM Service Registration

    As defined in [3], the following is a template covering information
    needed for the registration of the enumservice specified in this
    document.

    -  Service Name: "E2U+H323"
    -  URI Scheme(s): "h323:"
    -  Functional Specification: see "The E2U+H323 ENUM Service" section
    -  Security considerations: see "Security Considerations" section
    -  Intended usage: COMMON
    -  Author: Orit Levin
    -  Any other information that the author deems interesting: None

The E2U+H323 ENUM Service

    This document defines the "E2U+H323" service to be used in the
    "service" sub-field of the "enumservice" as defined in [3].

    The H.323 related ENUM record MUST be populated with a standard
    H.323 URL as defined in [2]. This URL MAY include parameters
    specifying the specific protocols and the transport means the H.323
    entity supports.

    The H.323 entity MUST fully comply with the procedures defined in [3]
    for both record retrieval and processing by the DNS client.

    If, as a result of the ENUM DNS lookup, an H.323 URL matching local
    policies and capabilities is retrieved, the procedure defined in
    section "Address Resolution Procedure using DNS" of [5] SHOULD be
    performed.

Conventions used in this document

    The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
    "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL" in
    this document are to be interpreted as described in RFC-2119 [1].

Security Considerations

    The h323-URL information, once populated in the DNS, effectively
    becomes publicly accessible. The access to the H.323 destinations

                   ENUM Service Registration for H.323 URL

    (published using ENUM) can be secured by techniques and procedures
    defined in H.235 [4] - the security framework for H.323. The
    framework defines means for achieving integrity, authentication,
    non-repudiation, encryption, etc. for H.323 calls.

IANA Considerations

    This document registers the "E2U+H323" ENUM service according to
    specifications and guidelines in RFC2916bis [3] and the definitions
    in this document.
