You use your phone system (also known as a PBX) every day, so you
already know that phone systems are responsible for handling your call

VoIP is short for Voice over Internet Protocol. VoIP is a way to make
calls across your Local Area Network (LAN) and or Wide Area Network
(WAN).

What is it ? It is a technology that can easily be very unreliable and
frought with complications and problems.

But that is the future! Today we _must_ replace reliable technologies
with
more profitable less reliable ones. Why do you think wireless is so
popular?

We've all been using VOIP for several decades, but it was the "phone
company" that did the VOIP, not the end-user customer.


It's more likely an ATM switch, although this is changing. ATM
service is indistinguishable from circuit switched with respect
to service quality and reliability.
