This circuit allows you to record audio from a telephone line into a tape recorder or computer soundcard without any hum. Most of the parts for this circuit can be scrounged from an old modem. With some rewiring work, it should possible to build this project into the old modem's case and re-use the built-in phone connectors. Note that some countries have laws that require the user of a phone recording device to notify the party on the other end of the line that they are being recorded.
