Then the phone at their end rings.

In more technical terms, computers on the internet communicate using a set of rules called TCP/IP. TCP/IP tells us that data needs to be sent across the internet in small pieces called packets. These packets are sequentially numbered so that the computer on the other side can put them together in the right order.

An internet phone uses the same process. Your voice is converted to a digital signal, like the sound from an old record when it is recorded on a compact disk. It is then broken into packets and transmitted over the internet to the destination computer. Just like your data. Once there your computer assembles the packets in the correct order and sends it to your telephone.
