  1. ENUM Applications and Network at Work Demonstration in collaboration with AG Projects Mr. Adrian Georgescu, Founder and CEO AG Projects

  2. ENUM applications and clients • An application that uses ENUM lookups to perform routing logic is an ENUM application • An ENUM client is part of the ENUM application and translated DNS requests into information understood by the application • An ENUM resolver is a standard or modified DNS resolver that sits within the operating system of the device where the ENUM application runs

  3. ENUM components

  4. How to use ENUM Is simple: • Register a number in official e164.arpa tree • Populate the zone with NAPTR records • Lookup the records Example used for the showcase: • Register an ENUM number (with http://sip2sip.info) • Map SIP address to the number (create also the SIP address) • Map email address to the number • Map a geo location to the number (web site or route planner) • Lookup the records

  5. ENUM tools for this showcase • ENUM Tier 2 interface (http://managed-dns.info) • ENUM client on Mac OSX (courtesy of John Cundall/Roke Manor Research) • Dig and nslookup utilities (standard DNS utilities) • ENUM enabled web browser (Firefox plug-in available from http://Falb.at) • ENUM enabled SIP service (http://Sip2SIP.info) • PSTN termination service (http://MCI.com) • Open Source SIP Proxy (http://OpenSER.org) Lets see ENUM at work: Point you browser to http://mci.ag-projects.com

  6. Concluding remarks • ENUM is a standard that should be embraced – It’s a no brainer • Global standards should ensure efficient roll-out and operations • Regulation should remain no or very light touch • Liberal numbering policy is essential • National competitiveness and regional information society agenda’s will assist the rollout of ENUM • Further questions and comments can be made to presenters at: • Robert.schafer@mci.com; Ronan.lupton@mci.com; ag@ag-projects.com
