How to record phone line calls using sound card?

[amirahmadian]

Hi everybody.
I'm looking for a way to record voice of my phone line using the sound card of my computer. I know I can't directly connect the telephone to sound card input (because the voltage levels and impedance may not match). Please note I want to record phone just using the "sound card" , because this way I'll be able to do the recording by any simple software (like Windows Sound Recorder).
Is there any device, module, circuit, etc that can help me to connect the phone line to the sound card (line-in or mic-in input)? (I prefer ready-to-use devices on the market) .

Here is an example to use an standard 3.5mm jack connector from telephone line.

You can connect this directly to line-in or maybe mic input of your sound card.
