voice authorization

Well, new to uplink, but already doing very well. In the shareware version i have already been able to rob over 2m credits with no problem..... except that i still can't get into the bank admin, as i can't get voice authorization. I have spent DAYS in fast forward mode waiting for some idiot to come by and talk into the microphone so i can record his voice and use it myself.... but with zero luck. Anyone that can help me?

You call the administrator's phone.

Which you can find on the company's public access server.

Which you can find on InterNIC.

And if you can't find that, Uplink's not the game for you.
