Qual A Serial Key Para Mount&blade How Can A Phone Interview Be Recorded In Australia Without Attaching To The Line (illegal) And Still Good Qual

How can a phone interview be recorded in Australia without attaching to the line (illegal) and still good qual - qual a serial key para mount&blade

Since it is illegal in Australia, something to the phone line do I connect an indie record used in conjunction with that, the quality is not the best. (if you know the other person know that they are registered, as well as the interviews for my company)
It should be an easier way?
Cheers
