The tools utilized in the past were simple and far from the current leading-edge instruments, such as a digital telephone recording device. Previously, telephone recording was done using simple extra wires which were 'connected to the line between the telephone company's central office and the subscriber that carried the signal to a pair of earphones and a recorder,' according to the aforementioned book. Eventually, the recording hardware was set up at the telephone company's main office itself, right onto the structures that held the inbound wire connections.
