Broadband telephony is useful because it
provides all the basic functionality of conventional telephony plus
additional features - all at a much lower cost.
One very useful feature that is
unique to VOIP (Voice over Internet Protocol), is the ability to acquire and use phone numbers in
other cities, states and even distant countries. This allows people
in that area
to make “local” calls to you, and for you to make “local” calls to
them. This effectively eliminates long distance calls that you
otherwise would pay.
Another unique feature of broadband telephony is the ability to take
your phone number with you wherever you go: to a country cottage,
on a business trip to Europe or Africa, or even when you move
permanently to a different location. With conventional phone
numbers, it is often impossible to retain a phone number even
if you are moving just a few blocks away.
