ITU-T already defined processes for working with other organizations, and TSAG enhanced these to include working with IETF • Guidelines were prepared for the SGs, including issues such as: - how to interact on ITU-T and IETF work items, including: * how ITU-T learns about existing and proposed new IETF work items * how IETF learns about ITU-T work items • Representation, including: - IETF recognition at ITU-T meetings and vice-versa - communication contacts - mailing lists • Document sharing, including: - drafting - the passing of documents between the Organizations - cross referencing Cooperation with IETF
IETF protocol defined in RFC 2916 • E.164 number can be used to look up a Uniform Resource Identifier (URI) - Web addresses most commonly known URIs • Allows using E.164 number in context of combined PSTN & IP services (email, fax, SIP address, coordinates, other?) For example: +44 1206 762335 5.3.3.2.6.7.6.0.2.1.4.4.e164.TLD What is ENUM?
Define and implement administrative procedures that coordinate delegations of E.164 numbering resources into the agreed DNS name servers • Director of TSB, on behalf of Administrations, to control the implementation of ENUM under e164.arpa on a trial basis, while the registering is done by RIPE NCC ITU-T Responsibilities regarding ENUM

Encourage more Sector Members (service providers) from Africa Region to participate in the technical SG activities • Change mentality and policy • under market-driven principles - market in Africa + Africans manage their own markets • Africans have expertise • From your contacts with top-level worldwide experts in the SG activities, to learn new trends of technology development, to defend your own interests, to gain confidence and to contribute to the global telecom standardization with African values. African participation in ITU-T
Problems: limited financial resources, and no fellowships available for technical SGs • Solution: • Regional cooperation • Sharing responsibility on subjects among countries and • representing the regional/groups at the ITU-T meetings • E-mail consultation: • - free ITU TIES accounts for ITU Members • - free electronic access to ITU Recommendations for ITU Members • Contact TSB directly or through regional organizations • ITU-T strengthens its presence in Africa by organizing meetings • in Africa • SEE YOU MORE AND MORE in ITU-T! ************ African participation in ITU-T
