Multi-Tech’s digital MultiVOIP provides toll-free voice and fax communications
over the Internet or Intranet. By integrating voice and fax into your existing
data network, you can realize substantial savings on inter-office long
distance toll charges. The digital MultiVOIP family is available in 24/48-port
(T1/PRI) and 30/60-port (E1/PRI) models. Both models connect directly to
the PBX or digital carrier service to provide real-time, toll-quality voice
connections to any office on your VOIP network.

							Highlights
MultiVOIP Applications. MultiVOIP is ideal for
businesses looking to reduce toll charges between
frequently called sites. MultiVOIP is a voice over IP
gateway that integrates seamlessly into your data
network and operates alongside an existing PBX to
simply extend voice capabilities to remote locations. It
is designed to help maximize investments already made
in the data and voice network infrastructure.
SaveThousands of Dollars Each Month. MultiVOIP can
save substantial amounts in long distance charges. Even
if a company uses one of the most inexpensive calling
plans, a MultiVOIP network can quickly return the
investment and begin paying the company back.
Easy Integration. With MultiVOIP, you avoid the hassle
and expense of replacing your existing routers, WAN
connections or phone system required by other VOIP
solutions. MultiVOIP simply plugs into your Ethernet
network. Neither your phone service or network is
placed at risk. Minimum requirements: Ethernet
network, WAN connection, IP addresses.
Award-winning Voice Quality. With MultiVOIP, you’ll
experience consistent toll-quality voice connections.
Using the Perceptual Speech Quality Measurement
(PSQM), Internet Telephony magazine found that
MultiVOIP delivered exceptional voice quality. In fact,
MultiVOIP outranked the competition.Interoperability. MultiVOIP utilizes the H.323 and SIP
protocols to provide complete interoperability with
other Internet telephony solutions. The inbound IP call
protocol is automatically detected and the voice
channel is dynamically configured to match. The
outbound IP call protocol is configured with the phone
number, allowing you the flexibility to call H.323 or SIP
devices from the same port.
Advanced Speech Technologies. MultiVOIP supports
the Differentiated Services (DiffServ) Quality of
Service (QoS) protocol which sets priorities for voice
and fax traffic and allows transparent delivery. DiffServ
helps move time-sensitive voice traffic across even
low-bandwidth WAN connections, like 56K DDS and
ISDN, with the priority and quality required by voice.
Other features such as adaptive echo cancellation,
forward error correction, bad frame interpolation,
tunable latency and dynamic jitter buffers, further
enhance voice quality.
Bandwidth Management. Bandwidth is used only when
someone is speaking.  The silence suppression/Voice
Activity Detection (VAD) feature is an option that
frees unused call bandwidth for data traffic. This is
significant, since callers are usually silent for 60 percent
of the call. When using silence suppression, MultiVOIP
also offers Comfort Noise Generation (CNG) at the
receiving end so the user knows the line has not
dropped. In addition, MultiVOIP supports voice
compression standards like G.729 (8:1) and G.723 (10:1).
These standards help minimize the bandwidth required
for voice. G.723, for instance, is the maximum
compression rate and requires only 5.3K bps (plus
minimal IP overhead). Even at maximum compression,
your VOIP solution will still provide toll-quality voice.
No User Training. MultiVOIP provides single stage
dialing by utilizing a Uniform Dialing Plan that is
consistent with the E.164 (PSTN) standard numbering
plan. This includes automatic appending and stripping of
digits to dialed numbers to ensure that users will not
require additional training to make VOIP calls. In fact,
placing calls with MultiVOIP is like using your existing
phone system.
Management. MultiVOIP is easily managed locally using
a windows-based software application or remotely by
the central office with a web browser or SNMP. Multi-
Tech also includes its own SNMP management
software called MultiVOIPManager which provides
central site configuration, management and call
monitoring for all MultiVOIP gateways on the network.
It utilizes a Windows interface that makes it easy to
view events like usage tracking, live use reporting, call
history, and voice quality statistics. In addition,
MultiVOIPManager eases administration by
automatically e-mailing call logs based on volume or
time.

Supplementary Services. MultiVOIP supports H.450
supplementary services to provide for call transfer, call
forwarding, call hold, call waiting, and name
identification. It also supports Q.SIG, an inter-PBX
signaling protocol, for networking PBX supplementary
services in a multi- or uni-vendor environment.  And,
with support for Dual Tone Multifrequency (DTMF),
users can access their voice mail over the VOIP
network.
Optional H.323 IP Telephony Gatekeeper. The
MultiVOIP Gatekeeper is complementary product to
the MultiVOIP Voice over IP gateway. The turnkey
hardware and software solution provides corporate
enterprise network managers and Intranet managers
the power to define and control how H.323 voice
traffic is managed over IP networks. With the
MultiVOIP Gatekeeper, network managers have the
ability to configure, monitor and manage the activity of
registered network end points. In addition, managers
can set policies and control network resources, such as
bandwidth usage, to ensure optimal implementation.
You Be the Judge. Industry experts have recognized our
VOIP gateways for their clarity. But don’t take their
word for it, or ours. You be the judge! Make a FREE
VOIP call over the Internet by dialing 1-877-TRYVOIP.
