Abstract

An apparatus and method is provided for forwarding incoming calls by utilizing a subscriber defined routing list. The routing list may comprise alternate telephone numbers to which calls placed to the subscriber'"'"'s number(s) will be routed. Subscribers may establish routing lists that allow incoming calls to be forwarded to other numbers for either all of their numbers or for selected groups of one or more numbers. Each group of numbers is identified by a unique group number. Incoming calls are forwarded according to a time-of-day or day-of-week, a percentage allocation, a specific date, an originating location of the calling party, or inputs by the calling party to prompts. Subscribers may use the group number to activate and configure forwarding options associated with subscriber numbers associated with the group.
