Call-routing mechanism for automatically performing number substitution in an integrated access device
First Claim
1. A method for enabling a digital communication device to provide call connectivity therethrough of a call, that is coupled to a first port of said digital communication device and has a destination telephone number, to a second port of said digital communication device for delivery to a communication circuit intended to be reached by said destination telephone number, comprising the steps of:
- (a) providing said digital communication device with a called number substitution mechanism that is operative to automatically selectively modify any of all the digits of which said destination telephone number is comprised;
(b) processing said destination telephone number of said call, in accordance with said called number substitution mechanism, and selectively modifying said destination telephone number to the extent necessary to produce an output telephone number that conforms with connectivity requirements for said communication circuit; and
(c) coupling said output telephone number to said second port of said digital communication device.

Abstract
A called telephone number substitution mechanism is incorporated into the call-routing software employed by the microcontroller of a customer premises-installed communication device, through which digitized voice and data services are supplied to a customer site. The number substitution mechanism automatically selectively modifies digits of an original (dialed) telephone number, as necessary, to conform with the connectivity requirements of the communication link serving the destination device, thereby enabling the call to reach the destination device.

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 a first port of said digital communication device and has a destination telephone number, to a second port of said digital communication device for delivery to a communication circuit intended to be reached by said destination telephone number, a called number substitution mechanism comprising:
-
memory containing a plurality of potential substitute telephone numbers; and
a telephone number comparator routine that is operative to compare said destination telephone number with said plurality of potential substitute telephone numbers stored in memory, and selectively modify any of all of the digits of which said destination telephone number is comprised to the extent necessary to produce an output telephone number that conforms with connectivity requirements for said 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 modify any of all of the digits of which an original telephone number is comprised of a call to an input port of said integrated access device as necessary to conform with the connectivity requirements of a communication link from an output port of said integrated access device to a called telecommunication circuit.
