Abstract
A common adjunct switch integrated with a telecommunications network and associated with a plurality of predetermined telephone numbers prefixed by a common code is provided with a facility which allows telephone subscribers that are assigned respective ones of the telephone numbers to personalize the way in which they receive long distance telephone calls. For example, such a subscriber may program his/her associated service record to put into effect call forwarding or call screening. In addition, each such subscriber may be associated with one or more caller identification numbers, in which a caller identification number is used to determine whether a call placed to a service number is billed to the called subscriber or the calling party.
