PC-to-PC phone calls usually use a protocol called H323. And the way it works is you put in the phone number or the IP address of the other computer and it makes a streaming call from that computer to the other using that protocol. And so it just sounds just like normal. You'll hear your computer speaker ring and you push a button and you can answer that call.
