Patent number: 8831201Abstract: A method and apparatus for managing ENUM records is disclosed. An apparatus that incorporates teachings of the present disclosure may include, for example, a broker having a detection element that detects a Resource Record (RR) submission made by an IP Multimedia Subsystem (IMS), and a comparison element that retrieves from an object-oriented data storage element a zone associated with the RR, identifies a Domain Name Server (DNS) responsible for processing said zone, compares the zone with a volatile memory of the DNS, and updates the volatile memory according to one or more differences detected. Additional embodiments are disclosed.Type: GrantFiled: August 10, 2006Date of Patent: September 9, 2014Assignee: AT&T Intellectual Property I, LPInventors: Bernard Ku, James Forsyth, Douglas Lin, John Richardson, Armstrong Soo

Patent number: 8654962Abstract: A system and method of delivering ringback audio content are disclosed. In one embodiment, the method includes receiving a connection request at an originating serving call session control function (S-CSCF) network element. The connection request indicates that a caller device has placed a call to a destination device associated with a ringback audio content service subscriber. The method also includes receiving a plurality of naming authority pointer (NAPTR) records at the originating S-CSCF network element from a telephone number mapping (ENUM) server. The NAPTR records include a plurality of ringback audio uniform resource indicators (URIs) associated with the destination device. The method also includes modifying the connection request to include the plurality of ringback audio URIs.Type: GrantFiled: March 19, 2013Date of Patent: February 18, 2014Assignee: AT&T Intellectual Property I, L.P.Inventors: Bernard Ku, Mehrad Yasrebi, Douglas Lin
