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 RFC 3761 [3]. + +2. 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 section "3. The E2U+H323 ENUM + Service" + - Security considerations: see section "5. Security Considerations" + - Intended usage: COMMON + - Author: Orit Levin + - Any other information that the author deems interesting: None + +3. 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 O.8.1 "Locating H.323 Destination" of [5] SHOULD be + performed. + + + + + + + +Levin Standards Track [Page 2] + +RFC 3762 ENUM Service Registration for H.323 April 2004 + + +4. 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 BCP 14, RFC 2119 [1]. + +5. Security Considerations + + The h323-URL information, once populated in the DNS, effectively + becomes publicly accessible. The access to the H.323 destinations + (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. An analysis of + threats specific to the dependence of ENUM on the DNS, and the + applicability of DNSSEC [6] to these, is provided in [3]. + +6. IANA Considerations + + This document registers the E2U+H323 ENUM service according to + specifications and guidelines in RFC 3761 [3] and the definitions in + this document. + +7. References + +7.1.
