Abstract
Territorial boundaries and the assignment of responsive telephone numbers are prescribed for a virtual telephone number. Telephone calls placed to that number, even though the territories are within a metropolitan or other relatively local area, are automatically routed to actual telephone numbers so that the responding telephone in each case depends on the territory from which the call is placed. For call processing, a switch receiving a call to a virtual telephone number momentarily suspends call processing and a first database is queried by entry of the calling station identity (ANI). The first database relates the calling station to a geographic location, preferably by postal zip code. Using the zip code, a second database, dedicated to the virtual number and relating zip codes to actual telephone numbers, is consulted. The telephone number assigned to the calling station's zip code is then returned to the switch. The switch resumes processing of the call to route it to that number. For multiple virtual telephone numbers, multiple second databases are provided, the first database serving as a common source for postal zip codes for entry into each second database. To set the content of a second database, an area map is produced from street segments and postal zip codes such that the map will encompass the territories. The territories are defined on the map by setting the boundary lines and from each territory the zip codes encompassed by the territories are extracted. To the zip codes, the actual telephone numbers are assigned, and the data for all of the territories are sorted for assembly into a file, or routing plan, for insertion into the second database.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
