Abstract

A system for selecting multiple interexchange carriers serving telephone switches interconnecting user telephone lines. Apparatus and a method interactive with telephone users creates data base records of user selected interchange carrier resources and encodes the user created data base records into telephone switch messages. The telephone switch messages are transmitted to telephone switches to enable the telephone switches to selectively interconnect user telephone lines with ones of the interchange carrier resources in accordance with user created data base records.
