Toll-bypass Long Distance Calling

Now multi-location businesses can use the Internet or a
private network (Intranet) for long distance voice and fax
communications and save thousands of dollars annually.
Instead of paying your long distance
carrier to route long distance
calls between offices, any IP
data network can route the
calls using a technology
called Voice over IP
(VOIP). It doesn't
matter if you are
using the Internet, a
private Intranet,
ISDN, DSL, frame
relay, wireless, or
satellite for your data
communications
network, as long as it
uses the Internet Protocol
(IP).

If you make frequent long distance calls to a remote site,
you already know the charges can add up quickly. Voice
over IP is designed to help you maximize the investments
you’ve already made in your data and telecommunications
network infrastructure by bridging them together to
provide toll-free communications.

This guide provides telecommunication managers and
data communications managers with an introduction to
Voice over IP and how they may benefit from voice and
data convergence.

What is VOIP?

VOIP lets you make toll-free long distance voice and fax
calls over existing IP data networks instead of the public
switched telephone network (PSTN). Today businesses that
implement their own VOIP solution can dramatically cut
long distance costs between two or more locations.

That Was Then...

For the past 100 years people have relied on the PSTN for
voice communication. During a call between two
locations, the line is dedicated to the two parties that are
using it. No other information can travel over the line,
although there is often plenty of bandwidth available.

Later, as data communications emerged, companies paid
for separate data lines so their computers could share
information, while voice and fax communications were
still handled by the PSTN.

This Is Now...

Today, with the rapid adoption of IP, we now have a far
reaching, low-cost transport mechanism that can support
both voice and data. A VOIP solution integrates seamlessly
into the data network and operates alongside existing
PBXs, or other phone equipment, to simply extend voice
capabilities to remote locations. The voice traffic
essentially “rides for free” on top of the data network using
the IP infrastructure and hardware already in place.
