Abstract
A subscriber dialed common access code, e.g., pqr, such as for directory assistance (411), fire service (611), or voice mail service (222) is translated into a predetermined seven digit number, e.g., tuv-wxyz. All or part of the subscriber's directory number (DN), e.g., abc-defg, is then prefixed and/or suffixed to the translated number to provide a re-constructed number which includes all or part of the subscriber's DN. The re-constructed number takes the form of part/all of [abc-defg] and tuv-wxyz followed by part/all of [abc-defg]. Thus, the re-constructed number incorporates all or part of the subscriber's DN allowing for differentiation among various subscribers who use common access codes permitting each subscriber call to be routed on an individual basis. This permits common access codes to be used by subscribers throughout the network, while routing some subscriber calls differently from others where the same dialed digits are used. In another embodiment, all or part of the caller's DN is combined either as a prefix or suffix with the dialed number for the selective routing of calls to the dialed number on an individual caller basis. This latter approach does not make use of a special access code in making the call.
