Abstract

A communication system includes an application server that includes logic to recognize that preference data in each of a plurality of data record entries of a subscriber record has a common value. Each data record entry includes a Uniform Resource Identifier (URI), and the subscriber record is stored in a telephone number mapping (ENUM) server. The application server also includes logic to issue a command to initiate contact concurrently with devices identified by URIs in the subscriber record via an Internet Protocol Multimedia Subsystem (IMS).
