How to record faint sound from the Mic input?

I need to record a phone conversation, but the sound from the Mic
input is so weak that recording and playing back in Audacity I hear
almost nothing. How can I either boost the playback or (even better)
boost the input so that the file is recorded in a hearable way?

Kubuntu 9.10. Thanks!
