Abstract
Abstract Disclosed audio signal recording methods and apparatus operate with a telephone set having a housing and a handset connected to a first modular jack in the housing via a handset cord having at an end thereof a first modular plug fitting into the first modular jack. For audio signal tapping purposes, there is provided a second modular plug fitting into the first modular jack, a second modular jack for receiving the first modular plug, and an electrical interconnection of the second modular jack with the second modular plug. The second modular plug is inserted into the first modular jack and the first modular plug into the second modular jack. Audio signals are tapped from the electrical interconnection of the second modular jack with the second modular plug and are recorded.
