• The primary ENUM service is VoIP
• in conjunction with IP phones and terminal
  adapters
• but ENUM and VoIP for residential customers has
  yet to overcome Metcalfe's law (n2 - n)
• most beneficial in corporate (private)
  environment
• as replacement of existing PBX or Centrex
  solutions
• preserving the existing dialing plan
• Corporate solutions as inroad for
• other services
• home workers, road warriors
