Answer 1

You can't!  Unless you record them or use a computer to eaves drop through Skype which is free PC 2 PC calling.  2 POTS lines could have an advantage using conference calling which isn't anonymous or a box that answers the second line and allows listening but it will ring if the ringer isn't disabled.  Easy to build uses a mosfet transistor and a 555 timer and an AND gate to answer and hang up automatically.  Just call the first line if it's busy call the second one. Look up telephone answering circuits in Google . Hope this helps
