• Resource intensive
• Not scalable
• Multilateral
• One interconnect
• Possibility of one commercial contract
• Minimal use of internal resources
• Network upgrades
• Federated
• Members control policy
• Trust
• Commercials

• identifies service provider or entity
• identify actual egress point
• Optimize routing
• Enables most efficient routing mechanism
• voice
• video

LNP and ENUM

• Number portability (local, mobile or full) is now
  available in US, Canada, Mexico and Brazil
• All Call Query (ACQ)
• Central Registry Approach
• Call Forwarding Approach
• Typically delivered via SS7/ C7
• ENUM Registries
• Private routing, public registry, carrier ENUM
  via ACQ
• Can be LNP corrected
• Enables expansion of ACQ to other Registry
  information beyond NP
• Features supported (video, wideband codecs,
  Presence)
• Call forwarding, call forking, non-traditional
  number plans
