Abstract
A method for determining the location of a VoIP caller includes receiving an emergency call from a VoIP phone from the internet via a VoIP enabling device. A device identifier of the VoIP enabling device through which the call from the VoIP device originated is received. The device identifier is compared against a pre-defined table of device identifiers, where each device identifier in the table has an associated physical location. The physical location of the VoIP enabling device is returned during the call from the VoIP phone.
