Answer 1

What you're describing is exactly what happens when you make a dial up connection to an ISP, but you replace the modem number with the number you want to call.

Answer 2

If your laptop has a modem with it's own line-in and line-out (like many PCI modem cards for desktops do) then you can use the laptop as a dialler and  use a headset-mic to speak-listen.
