发明名称 DETERMINING A PHYSICAL LOCATION OF A VOIP ENDPOINT DEVICE UTILIZED TO ORIGINATE AN EMERGENCY CALL
摘要 In one embodiment, a method and system for enabling determination of a physical location of a Voice Over Internet Protocol (VoIP) endpoint device utilized to originate an emergency call are described. A network location associated with the VoIP endpoint device is automatically detected. The VoIP endpoint device is coupled with a VoIP network via a port of a network device (e.g., a wireline or a wireless network device). The network location includes an identity of the network device and an identity of the port. The network location is saved and upon initiation of an emergency call, the VoIP endpoint device forwards the network location to a device capable of converting the network location to a physical location.
