- receiving at a control device a signaling message indicating a communication request from the user;
using information in the communication request to retrieve call control criteria from a database, where the call control criteria has been derived from selections previously made by said user via a web server; and

Abstract
A system includes a tandem access controller (TAC) coupled to a PSTN, where the TAC allows a subscriber to set-up and make changes to the configuration of his/her phone line or other communications device. Such changes include selective call forwarding. The TAC is controlled by the subscriber using the web. The TAC is coupled internally to the PSTN in a local service area and is outside the subscriber'"'"'s central office. A calling party makes a first call to the subscriber using the subscriber'"'"'s public telephone number. The TAC receives the first call prior to the call reaching the subscriber'"'"'s terminating central office. The TAC then carries out the subscriber'"'"'s instructions for the first call, such as making one or more second calls using telephone numbers different from the subscriber'"'"'s public telephone number. When the second call is answered, the answering phone is connected by the TAC to the caller.
