Abstract
A fingerprint is received from a communication endpoint. The fingerprint is based on a hardware identifier of the communication endpoint. For example the fingerprint may be based on a Media Access Control (MAC) address of the communication endpoint. A request for an emergency call from the communication endpoint is received that also includes the fingerprint. For instance, a user may initiate a 911 call from the communication endpoint. The emergency call is established. After the emergency call is disconnected, a request for an emergency call back is received. For example, if the emergency call prematurely disconnected, the emergency call back is initiated. The request for the emergency call back is routed to the communication endpoint based on the fingerprint to ensure that the emergency call is properly completed.
