Abstract
A method of logging call data for failed emergency calls includes: receiving from a calling party an emergency call that is to be routed to a Public Safety Answering Point (PSAP) (40) over a telecommunications network (20); determining if the received emergency call is connected to the PSAP (40); and, if the received emergency call fails to be connected to the PSAP (40), then capturing selected call data regarding the failed emergency call and recording the captured call data.
