Abstract
A system and method for concurrently ringing a subscriber's wired and mobile stations, where the wired station is served by a wired telecommunications network and the mobile station is served by a wireless telecommunications network. The call is routed to a network interface point of control from either the wired or wireless networks and the network interface becomes the point of control for the call. The call is initially offered to the mobile station by the network interface point of control, and before the mobile station rings, the call is offered to the wired station so that the wired and mobile stations ring concurrently.
