A rule-based intelligent call forwarding 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, which 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 a registered communication device, parses rules associated with the called party, and terminates the call request responsive to the rules parsing and presence determination. Methods and other systems are also provided.
