Abstract
An IP system receives a call placed to an ENUM address. The IP system transfers a signaling message indicating the ENUM address to a processing system. For a call to a ported number, the processing system translates the ENUM address into the LRN for a communication node that serves the called party and returns the LRN to the IP system. The IP system routes the call based on the LRN.
