Abstract

When telephone calls are placed by dialing a special number such as an “800” number, the dialed number is converted to a specially configured translation number that includes a destination output set of digits which are preferably the last four digits of the dialed number. This translation number is transported over the network from an originating switch to a terminating switch which then outputs the output set to the destination. Advantageously, the terminating switch also replaces the prefix portion of the translation number with an output prefix consisting of at least the NXX portion of the dialed number and outputs this prefix along with the output set to the destination for use in call tracking.
