Audio Hijack and WireTap do not necessarily need to get the audio via a microphone input.
All audio in OS X is routed through the CoreAudio Framework.

These programs simply latch onto the audio output of any CoreAudio process.
They can capture the audio from any mac program.

All you would need is a simple telecom app like HoldOn (free)

and your mac plugged into the phone line when you dial your voicemail.
Use HoldOn to pick up the phone and pipe the audio to your mac speakers (which goes through CoreAudio)

AudioHijack or WireTap can listen to the Audio from HoldOn and record to a number of formats. Audio Hijack has a very nice effects system which allows you to use any AudioUnit plugin to effect the incoming stream. Some basic mixing AudioUnits come with OS X. This could be particularly handy for removing line spikes or other noise. Of course that could be done after the fact as well.

So no hardware is needed for this trick. Audio Hijack will probably work in demo mode long enough to get what you need.
If not, it is a mere $16 shareware fee.

Hey all. I have a couple voicemails that I simply must get on .mp3 (I've brought them up before). What I'm curious about is would it be possible to use the Mac internal modem to dial into the voicemail system then record the
calls in Garage Band (or any other application)?
