1. A method of detecting a prank emergency call, comprising: reporting a first prank emergency call from a given wireless device to a networked physical prank call database; storing a first current location of said given wireless device initiating said first prank emergency call, together with a unique global identifier of said given wireless device, in said physical prank call database; subsequently receiving a subsequent emergency call; obtaining a subsequent current location of a subsequent wireless device while making said subsequent emergency call; querying said physical prank call database for a correlation between said subsequent current location and said first prank emergency call; and dropping said subsequent emergency call when a correlation is established between said subsequent current location and said first prank emergency call.
