iOS record phone calls audio on a jailbroken device

Question

I want to be able to record the audio of a phone call on a jailbroken iOS device.
I can think of two possible ways:
1)Start the microphone recorder once the phone call begins and record 2)Capture the actual audio stream of the phone call

Is any of the above possible? Ot any other?

Answer 1

Voice memo recorder only picks up audio from the microphone - therefore unless you are using speakerphone, it won't record the other person.
