Abstract
Methods and systems may provide carrier ENUM based routing for subscriber devices (e.g., voice or other multimedia services over IP) to locate and to connect to subscriber devices of another IP peering carrier. A private ENUM database may be used to connect subscribers of disparate carriers using a domain for designated breakout gateway control functions.
