Abstract
Systems and methods are presented for providing updated VOIP terminal location information to emergency call service providers, in which RFID tags are positioned at various locations within an enterprise and coded with unique tag data. A database is provided with a mapping of RFID tag data and tag locations in the enterprise, and the VOIP phone terminals are equipped or otherwise connected with RFID tag readers. The VOIP phones read the tag data upon initiation of a 911 or other an emergency call and report the tag data to a network server that determines the VOIP phone location according to the tag data and provides the phone location to the emergency call service provider.
