There are any number of reasons you may want to record your landline phone calls on your computer. For instance, you might want to catch someone in a lie, for use as evidence in court, or simply remind someone of a promise they made. All you need is a simple device that attaches to both your phone and your computer. Once connected, you can turn your phone calls into digital files that you can e-mail or burn to a CD ROM.
Purchase a PC phone recording system (see resource links). These can be purchased online for between £19 and £104.
Unplug the line coming into your phone from the wall. Plug the line into the recorder and run a line from the recorder into your landline.
Connect the USB cable from the recorder to a USB port on your computer.
Turn the device on. Now, whenever you answer a call, the phone recording device will automatically record your conversation and save it to your computer. The conversation can be saved as a .wav file or as an MP3. This way you can save it to a thumb drive or send it to someone else via e-mail.
