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

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
