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 doesnt
matter if you are
using the Internet, a
private Intranet,
ISDN, DSL, frame
relay, wireless, or
satellite for your...

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...

Immediate Cost Savings
VOIP solutions provide the potential to save substantial
amounts in long distance charges. Businesses with remote
offices worldwide or just in a different area code miles
away can profit from a VOIP solution. Even with the most
inexpensive calling plans, a VOIP network, such as
Multi-Tech’s MultiVOIP gateway solution, can quickly
return your investment and begin paying you back.
In fact, after the one-time investment is paid off, the
VOIP solution begins to create profit for your...

Create Off-premise Extensions
Extend the reach of your PBX into home office locations.
Simply connect a VOIP solution to the PBX at the
corporate office, and another VOIP solution at the remote
office. Now, anyone can place calls to the remote office
by simply dialing an extension number.
Replace Expensive Tie Lines
A company that utilizes tie lines to connect branch office
PBXs to the corporate PBX can now use their own IP-based
Wide Area Network to complete the call.

Bandwidth Requirements
One common misconception about VOIP is that it is a
bandwidth hog, when, in fact, voice is a very efficient type
of traffic. Voice compression standards like G.729 (8:1)
and G.723 (10:1) are used to minimize the bandwidth
required for voice. G.723, for instance, is the maximum
compression rate and requires only 5.3K bps (plus an
added 7-8K bps for IP overhead). Even at maximum
compression, your VOIP solution will still provide near
toll-quality voice.
As a rule of thumb, 14K bps...

VOIP Server Cards
VOIP server cards can be an economical VOIP solution.
However, they must be compatible with the server and
operating system and installations can be complex.
IP-based PBX
The IP-based PBX is usually software running on a
computer based server. However, it often requires a
forklift upgrade of the existing
PBX, or at a minimum, an
extensive software and/or
hardware upgrade. An IP-based
PBX is typically marketed to
new installations where no
legacy system is in place.

The Multi-Tech VOIP Solution
Multi-Techs award-winning
MultiVOIP provides an
easy and low-risk way
for your business to
save on long distance
voice and fax costs.
Easy to Install
You dont have to change your PBX, data network, or
Internet/Intranet access to implement the MultiVOIP
solution. There is no
integrating this device
with a PC, a server, or
operating system. And
to simplify installation,
the central site can
preconfigure all units
before sending them to
the remote sites.

Requirements
You probably already have what you need to deploy a
MultiVOIP network and start saving on long distance calls.
To determine the number of ports that you need, first
determine what percentage of the long distance bill is used
for intra-office communication (typically between 25-
40%), then multiply the percentage by the number of lines
at the location. If you are using tie lines, for every line
that you support, you will need one port on the MultiVOIP.
