I don't know any way to do it with a voice modem, but there are a number
of devices (at least 3 or 4) that you can use to record phone
conversations with your PC (and OneNote). I used to have one or two of
them around here, but since I don't have a landline phone here I stashed
them away somewhere.
Basically they connect your phone to the computer's microphone jack so
that the computer sees the phone handset (both sides of the
conversation) as a microphone and lets you easily record.
