1. PT0000. 00/00/04 ENUM Applications and Network at Work Demonstration in collaboration with AG Projects Mr. Adrian Georgescu, Founder and CEO AG Projects Demonstration in collaboration with AG Projects Mr. Adrian Georgescu, Founder and CEO AG Projects

2. 23/01/2014 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. 23/01/2014 3 ENUM components

4. 23/01/2014 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. 23/01/2014 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)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. 23/01/2014 6 Concluding remarks ENUM is a standard that should be embraced – Its 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 agendas 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.comRobert.schafer@mci.comRonan.lupton@mci.comag@ag- projects.com
