When Ray calls Ned at the police station, he times the call so that he wouldn't be 'traced' and clears it after precisely 58 seconds. The call would have been via digital exchange and the number would have been displayed instantly as it is a feature provided for billing purposes. Previous electro mechanical (strowger) exchanges required time for the call to be manually traced through selector banks and distribution frames, often through several different buildings miles apart and always referring to wiring records. The time taken varied enormously and depended upon the skill and knowledge of the engineers. Strowger exchanges are now obsolete and would have been highly unlikely to be operating in the area of Florida where the movie is set. Hollywood even today has not moved on from this antiquated and outdated plot device.
