Abstract
A method is provided for routing an emergency call. The method comprises receiving an emergency call and identifying an end node associated with the call. The end node may be a communications device involved in establishing the emergency call that is geographically near the originator of the emergency call. A look-up table is then accessed to identify the appropriate public safety answering point (PSAP) associated with the end node, and the emergency call is routed to the identified PSAP.
