Abstract

See full text

A method and system are provided for dual ringing of a Centrex line and a wireless extension of the Centrex line. With dual ringing functionality, a single destination number dialed by a calling party results in ringing of both a Centrex line and a wireless extension of the Centrex line. In one preferred embodiment described herein, the dual ringing functionality is implemented with a network element (e.g., a service node) separate from a switch (e.g., a service signal point). In this way, the dual ringing functionality is available to users of any end office switch that uses the separate network element--not only to those users of a particular type of end office switch. Furthermore, unlike switches, network elements, such as service nodes, typically do not require vendor approval for modification. Additionally, the dual ringing functionality of these preferred embodiments is switch independent and provides an open platform.
