[TriLUG] recording a phone call from within Mac OS X?

[John Wheeler]

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.
