Mechanism for automatically substituting calling number information in an integrated access device
First Claim
1. A method for enabling a digital communication device to provide, to a called communication circuit being called from a calling communication circuit, information representative of a telephone number other than that associated with said calling communication circuit, said method comprising the steps of:
- (a) providing said digital communication device with a calling number substitution mechanism that is operative to automatically selectively modify calling telephone number information, that is associated with said calling communication circuit, and is transported to said called communication circuit in the course of said digital communication device placing a call to said called communication circuit;
(b) processing said calling telephone number information, in accordance with said calling number substitution mechanism, so as to selectively modify said calling telephone number information to produce modified telephone number information representative of said telephone number other than that associated with said calling communication circuit; and
(c) coupling said modified telephone number information to an output port of said digital communication device for transport to said called communication circuit.

Abstract
A calling telephone number information substitution mechanism employs an automated calling number substitution template to selectively modify ‘calling’ party number information that is transmitted to the called party. This serves to associate the calling party who has placed a call that cannot be directly dialed from an outside phone with a valid telephone number identified with the premises originating the call. As a result, the called party, such as a 911 emergency facility, is able to correctly locate and place a return call to a valid telephone number at the premises from which the call has been placed.

9. For use with a communications controller of a digital communication device that is configured to enable a customer of a communication service provider to conduct time division multiplexed and packetized voice and data communications with a digital communications switch of a digital telecommunications network, said communications controller containing a call routing mechanism that provides call connectivity of a call, that is coupled to an input port of said digital communication device and has a destination telephone number, to an output port of said digital communication device for delivery to a communication circuit intended to be reached by said destination telephone number, a calling number substitution mechanism comprising:
-
memory containing a plurality of original telephone numbers; and
a telephone number comparator routine that is operative to compare a calling telephone number with said plurality of original telephone numbers stored in memory, and to selectively modify said calling telephone number information to produce modified telephone number information representative of a telephone number other than that associated with a calling communication circuit. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A telephone number substitution mechanism for use with call-routing software of an integrated access device through which time division multiplexed and packetized voice and data services are supplied, and being configured to automatically selectively modify contents of a calling telephone number as part of call signaling information forwarded to an output port of said integrated access device to a called telecommunication circuit.
