A system and method include implementing and accessing a subscriber's telecommunications services, using a graphical user interface (GUI) via the Internet, and an interactive voice response (IVR) system via the public switched telecommunications network (PSTN). The system and method enable a subscriber to review, schedule and modify call forwarding information stored and implemented by a service control point (SCP) through a common server from any dual tone multi-frequency (DTMF) telephone and IVR system via the PSTN or any GUI and Web client via the Internet. The subscriber is able to build and edit call forwarding data, such as a scheduler and priority and rejection screening lists, by the GUI via the Internet for subsequent implementation.
