Patent ID: 7627108

Claim:
A system for providing an ENUM specification in an LNP environment, said system comprising: an originating office of a first service provider which receives a dialed call from an originating device; a terminating office of a second service provider to which the dialed call is directed by the originating office; a combined LNP and ENUM database in communication with both said originating office and said terminating office; an originating means, located at said originating office, for looking up and using LNP and ENUM information from said combined database; and a terminating means, located at said terminating office, for looking up and using LNP and ENUM information from said combined database, wherein the combined LNP and ENUM database receives a single LNP query based upon dialed digits from the originating means, the combined LNP and ENUM database returns an LNP response containing an LRN of the terminating office to the originating means, the LRN indicating that a terminating device has either a POTS format or an IP format such that a POTS format initiates a POTS routing and an IP format initiates the return of ENUM information to the originating means in an ENUM response with the LNP response, and the originating means receives the ENUM response and analyzes the ENUM response to determine what information format is necessary for the terminating device.
