Abstract
An emergency call service system, such as an E911 system, provides service system personnel with the addresses of abandoned calls to facilitate abandoned call follow-up. When a call comes in to a '911' ANI controller (21), the calling number is recorded. If the call is abandoned prior to being assigned by ACD 23 to an agent position (27-28) for being answered, an abandoned call ALI function (25) is invoked to obtain information pertaining to the calling number from a database (20), similarly to a non-abandoned call. When obtained, the information is displayed on equipment (29) such as a printer, terminal, or PC, to make it available to system personnel for use in following up on the call. The ANI controller serves both '911' emergency calls and emergency call-handling agents as well as other calls and other users, by switching the emergency calls to the agents and switching the other calls to the other users.
