Abstract
A call routing system for use with a wireless telephone systems is disclosed. The system, which monitors the subscriber'"'"'s current physical location, determines the device to which a call should be terminated, and routes the call. The device can be any IP telephone, including a cable television system adapted to IP telephony. The system routes calls without direct subscriber actions, without a second telephone number, regardless of the time of day and day of week. Various options can also apply to a call, determined by subscriber-established preferences, when specified criteria are met, or calls can be limited to/from specified telephone numbers. The system and method uses signaling techniques that will allow routing of the call, along with any authorization or restrictions, to be done remotely from the actual switching for the call. Call events are transmitted to the call routing system while the communications path of the call is held at the switching system awaiting call routing information. The identity of the subscriber is established using existing means that are used to authenticate the user. The wireless phone user does not have to enter any additional codes or identification to obtain access to the call routing system.
