How Voice over IP (VoIP) Works
 Voice over IP, or VoIP for short, is a new technology that enables the
transmission of voice calls over the Internet. It doesn’t use the traditional
telephone cables that have been in place for decades, but rather makes
use of the various types of modern Internet infrastructure.
 VoIP technology converts the audio into small, separate packets and
sends each one individually. Think of them like envelopes, with small parts
of the message inside each one. Once reaching the destination, these
individual packets are put back together and played in sequence to
recreate the audio. This happens so fast that the listener doesn’t notice
any gap in the sound, and hears the other person’s voice just as if they
were talking normally. Live video calls are sent in the same way but require
a much larger amount of bandwidth.
