Motorola ATRIX 4G phones

I have a Motorola ATRIX 4G phone and new sometype of app that will allow me to record all phones calls and save the calls to a file on my phone. I have tried over 20 apps with no results. Does anybody know of a app that will work opn this phone. I need this for the courts, investigations etc at work. It is very legal to do this in my state. Louisiana as long as one of the party to the call is aware.
