I bought my girlfriend one of these.  If you are at a touch-tone
phone, you just dial touch-tones in response to voice prompts like any
answering machine.  If you are on a rotary phone and you leave no
message (silence for a few seconds), it figures you have a pulse phone
and goes into voice response mode.  It gives you prompts and you
respond by saying simple words.  For example the conversation might
go:

Machine:  Entering first digit of remote access password now.  Enter 0...
          Enter 1...Enter 2...Enter 3...Enter 4...
Person:   Enter.
Machine:  Enter second digit...Enter 0...Enter 1...Enter2...
Person:   Enter.
Machine having accepted 42 as your password plays message 1.
Machine:  Repeat?
Person:   Repeat.
Machine repeats message.
Machine:  Repeat?...
No response from person, machine plays 2nd message.  And so on.
