  • Computer program and method for automatically setting up call routing for a metropolitan statistical area
    Patent number: 6834104
    Abstract: A computer program that automatically creates call routing data files for setting up call routing in a new telecommunications switch (10) or for adding a new MSA to an existing switch. The computer program broadly comprises a code segment for receiving NPAs and NXXs for an area such as an MSA; a code segment for receiving information differentiating local calls from long distance calls for at least some of the NPAs and the NXXs in the area; and a code segment for analyzing the NPAs, the NXXs, and the information differentiating local calls from long distance calls and for automatically creating at least some of the call routing for calls originating in the area.
