Abstract

A system and method automatically route telephone calls to a substitute telephone number that may differ from the dialed telephone number. The substitute telephone number is obtained from a call management module which determines the number based on various factors including, for example, modes, filters, schedules, and the like. A dynamic number portability database may be used to implement the call routing functionality.

Claims

receiving an indication of a telephone call being initiated by a caller, the telephone call having a dialed telephone number;

passing the dialed telephone number to a call management module;

obtaining, from the call management module, a substitute telephone number; and

routing the telephone call to the substitute telephone number.

2. The method of claim 1, wherein the receiving, passing, obtaining, and routing steps are performed by an originating switch associated with the caller.

3. The method of claim 2, wherein the originating switch comprises one selected from the group consisting of:

a central office (CO);

a mobile switching center (MSC);

a private bank exchange (PBX); and

a gateway switch.

4. The method of claim 2, wherein routing the telephone call comprises sending a transmission to a destination switch, the transmission comprising the substitute telephone number.

5.
