Abstract:
A system and method for communicating location information of a VoIP subscriber to a public-safety answering point may include receiving an E-911 telephone call from a VoIP telephone. Location information associated with the VoIP telephone stored in a database may be requested. The location information may be received in a signal formatted substantially the same as a signal format for communicating caller identification information. The location information may be displayed at a public-safety answering point. In one embodiment, the location information may be displayed on a video display.
