发明名称 METHOD OF ASSIGNING TELEPHONE AREA CODES
摘要 The processing of a telephone call identified in part by an area code associated with a particular geographical area results in forwarding the call totelephone equipment located in the geographical area. Such processing is enhanced by associating a unique area code with an entity other than a geographical region or telephone service and then forwarding a telephone call identified in part by theunique area code to telephone equipment associated with the entity even though that equipment may be located in a geographical area associated with a different areacode.
