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.
