A method and system for locating a network device connected to a proxy network device in an emergency situation. When an electrical connection, whether through physical wires or over a wireless interface such as spread spectrum technology is made on a proxy network device (e.g., analog terminal adapter (ATA), analog or digital Private Branch Exchange (PBX) system, Digital Enhanced Cordless Telecommunications (DECT) devices, gateway, bridge, router, switch, etc.) for a network device, the proxy network device sends a connection identifier such as a port number or wireless channel number, Device IDentifier (DID) number, etc. to an emergency location server network device to associate the connection identifier on the proxy network device with connected network and with a current physical location to be used in an emergency. When an emergency event occurs, the connection identifier is used to determine an emergency current physical location that is used by first responders.
