Abstract
Methods and systems for obtaining the location of a caller during an emergency or other telephone call. Before or during a call, a phone system can obtain from one or more sources a subscriber access line identity associated with a subscriber location record that includes a subscriber access line identity attribute and a subscriber location attribute. A phone system can send a query that includes the subscriber access line identity to a subscriber location query system that returns a subscriber location record or a subscriber location to the phone system. The phone system can then display the caller location information to a phone system, an agent or operator so that emergency services can be quickly and accurately dispatched. Using similar procedure and a memory, phone systems can also determine if a subscriber phone has or is changing location. Methods for testing the emergency call capabilities of a subscriber access line.
