Abstract
A system for providing a simultaneous ring service for a subscriber. The system allows a subscriber to identify one or more telecommunication units that should be rung simultaneously with the subscriber's landline telecommunications unit when a call is directed to the landline unit. A list of numbers to be simultaneously rung is maintained by the subscriber and may be stored at a service control point. Ringing wireless numbers is initiated prior to ringing wireline numbers to account for timing delays inherent in wireless communications systems.
