ENUM Applications and Network at Work

• Demonstration in collaboration with AG Projects
• Mr. Adrian Georgescu, Founder and CEO AG Projects

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

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

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
