Regular Telephone
vs
VoIP

THE ONLY DIFFERENCE BETWEEN VOIP
AND REGULAR TELEPHONY IS THE
PRICE.

Internet telephony and regular telephony are unlike
one another in almost every possible way. Internet
telephony depends on turning voices into packets
of data and sending them through a relatively dumb
network—the Internet. Those packets are sent to
relatively smart devices: computers, PDAs, and IP
phones.
Is VoIP Secure?
To the extent that VoIP is just another
data application, it has no inherent
protection against eavesdropping, but in
practice VoIP is even more secure than
old-style telephony. That wasn't always
the case.
Savings On Long Distance
Changes?
The VoIP infrastructure on a campus such as
UTEP still uses the public phone network once
it leaves our campus. Our calls will not go out
over the public internet.
Quote

As phones become full-blown computers in
their own right; as computers, PDAs, and other
devices become phones; and as the
boundless Internet becomes a phone network,
we'll be surrounded by telephony choices that
dazzle, delight, and befuddle us. Welcome to
the world of VoIP.
