Is there software available that will allow recording from a phone line to a computer? - conversation recording software

I know the sound of a phone can pass through the modem. You can hear when you use the internal fax and dial-up. I hear the sound and the voice from the loudspeaker of the computer. Is there a software that can be started and listening on the modem and the telephone conversation without any additional hardware covered?
