Abstract

An emergency information system comprises an interface and a processing system. The interface is configured to receive first call signaling for an emergency call from a call processing system wherein the first call signaling indicates a call back number. The processing system is configured to process the first call signaling to determine a destination for the emergency call, generate second call signaling indicating a key and the destination, and generate a database message indicating the key and the call back number. The interface is further configured to transfer the second call signaling to the call processing system and transfer the database message to a database system.
