Introduction to VoIP
Voice over IP: A VoIP (Voice over Internet Protocol) phone call is transmitted over a data
network, such as the internet. The “Voice Over Internet Protocol” is a catch all for the
protocols and technology of encoding a voice call that allows the voice call to be slot-
ted in between data packets on a data network. Such data networks may be the public
internet, a corporate intranet, or a managed network used by traditional long distance
and international providers. VoIP phone calls, if properly engineered, sound just as good
as a circuit switched TDM phone call - the ones we make and receive every day. There
are three main benefits to VoIP phone calls:

as a circuit switched TDM phone call - the ones we make and receive every day. There
are three main benefits to VoIP phone calls:
First, they may potentially be cheaper. Since the data network is typically charged on a
flat rate and thus the marginal cost of making a VoIP is zero, how much cheaper
depends on: 1: The cost of terminating the VoIP call into the traditional phone network.
(Figure a penny a minute.) 2: The price of a standard circuit switched TDM call. They’ve
been getting cheaper over the years. 3: How much tax is levied on both. Taxes are hor-
rendous on traditional circuit switched long distance calls. They aren’t so big, yet, on
VoIP calls, which are classified by some regulatory agencies as “information services,”
not voice phone calls. Therefore they escape most taxes.

Second, you may achieve the benefits of managing a voice and data network as one
network. If you have IP phones, moves, adds and changes, will be easier and cheaper.
IP phones are basically networked computers. They have individual addresses, with
memories, and user profiles. Their software upgrades are typically centrally managed
using standard computing systems. In short, they’re “user friendly” to manage and can
largely be managed remotely.

Third, and the key attraction of IP telephony - is added (and integrated) new services,
including integrated messaging, voice emails, number portability, caller ID with name,
call waiting, call forwarding, take your area code with you, plug into the internet any-
where and make free calls from anywhere in the world. And best of all, you can typi-
cally manage your phone via a website on the internet, which can provide complete call
accounting. A VoIP is typically a much better animal than today’s circuit switched phone.
