ABSTRACT:
An intelligent interactive call handling system is provided that typically includes a central office, a service control point, and an internet call routing system. The central office typically triggers a query responsive to receiving a call request. The service control point is coupled to the central office, receives the query, and triggers an internet call routing query. The internet call routing system, which is coupled to the service control point, typically receives the internet call routing query, determines presence of the called party with respect to at least one registered communication device, sends a prompt to the called party at said at least one registered communication device responsive to the presence determination, receives a reply from said at least one registered communication device, and routes the call responsive to the reply. Methods and other systems are also provided.
