Highlights

MultiVOIP Applications. MultiVOIP is specifically

targeted at 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 existing PBXs, or
other phone equipment to simply extend voice
capabilities to remote locations. It is designed to help
you maximize investments you’ve already made in
your data and voice network infrastructure.

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.

Save Thousands of Dollars Each Month. MultiVOIP

can save your company substantial amounts in long
distance charges. Even if your company uses one of the
most inexpensive calling plans, a MultiVOIP network
can quickly return your investment and begin paying
you back.

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.

Internet Telephony magazine (March 1999)

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. In addition, MultiVOIP
also supports T.38 real-time fax relay interoperability
among other VOIP equipment.

PSTN Fail-over. PSTN fail-over allows MultiVOIP to

automatically route calls over the PSTN network
when the IP network is down. MultiVOIP continually
checks if the LAN/WAN is down. If it detects a
problem, MultiVOIP switches to “survivability mode”
transparently routing all calls over PSTN lines
connected to the MultiVOIP gateway. MultiVOIP
continues to monitor the connection and automatically
switches back to the LAN/WAN once the problem is
corrected.

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 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.

Complete Support for Multiple Telephony

Interfaces. For maximum investment protection, the

MultiVOIP two, four and eight-port models
accommodate changing communication needs by
providing a programmable FXS/FXO and an E&M
interface for each port. This allows MultiVOIP to
connect directly to a phone, fax machine, key phone
system or PBX. It automatically detects whether the
incoming call is a voice or fax call. The single port
MultiVOIP supports either FXS or FXO interfaces,
depending on model, while the digital MultiVOIP
connects directly to a PBX or PSTN line via T1/E1 or
PRI.

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. In
addition, MultiVOIP supports SIP extensions providing
call forward and call transfer capabilities.

Integrated Gatekeeper. The MultiVOIP family now

includes models with an integrated gatekeeper to
facilitate call management in a Voice over IP network.
These cost-effective MultiVOIP gateways provide
centralized phone book management as well as deliver
the power to define and control how H.323 voice
traffic is managed over IP networks. With the
integrated gatekeeper, network managers can
configure, monitor and manage the activity of
registered end points. In addition, they can set policies
and control network resources, such as bandwidth
usage, to ensure optimal implementation.

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 an
added 7-8K bps for IP overhead). Even at maximum
compression, your VOIP solution will still provide toll­quality 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.

Avaya Small Office Media Gateway Solution. Avaya

and Multi-Tech have partnered together to provide an
affordable small office media gateway solution that
delivers the features of Avaya’s MultiVantage

TM

software to the branch offices of large corporations.
The Multi-Tech MultiVOIP gateway, with integrated
gatekeeper, cost-effectively extends the call features
and networking benefits of a centralized Avaya Media
Server to small branch offices, utilizing traditional
analog devices, over an IP infrastructure. MultiVOIP
also renders local office survivability, in the case of a
LAN or WAN failure, by providing local, reliable
PSTN trunking.

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.
Hear for yourself how clear the connection can be.

Management. MultiVOIP is easily managed using a

Windows-based software application, 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.
