Easy integration
With MultiVOIP, you avoid the hassle and expense of replacing your existing
routers, WAN connections or phone systems 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
outranked the competition.
Interoperability
MultiVOIP utilizes the 1-1.323 and SIP protocols to provide complete inter-
operability 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 1-1.323 or SIP devices
from the same port. In addition, MultiVOIP also supports T.38 real-time
fax relay for interoperability among other VOIP equipment.
PSTN fail-over allows MultiVOIP to automatically route calls over the PSTN
network when the IP network is congested or completely down. This feature
heightens reliability and augments QoS when conditions threaten to under-
mine voice quality. Utilizing user definable controls, MultiVOIP continually
checks if the LAN/WAN is threatened by packet loss or latency, or to see if
the network is completely 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 conditions improve.
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 s6K and ISDN, with the priority
and quality required by voice. Other features such as adaptive echo cancella-
tion, 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 FXS and FXO interfaces, while the digital
MultiVOIP connects directly to a PBX or PSTN line via T1,E1 or PRI.
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 band-
width for data traffic. This is significant, since callers are usually silent for
60 percent of a 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 0.729 (8:1) and 0.723 (10:1). These standards help minimize the bandwidth
required for voice. G.723, for instance, is the maximum compression rate
and requires only 5.310 bps (plus an added 7-8K bps for IP overhead). Even at
maximum compression, your VOIP solution will still provide toll-quality voice.
No user training required
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.
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 addi-
tion, 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. In addition, MultiVOIP sup-
ports SIP extensions providing call forward and call transfer capabilities.
Single-port protocol
The MultiVOIP family now includes models with SPP (single-port protocol),
a non-standard protocol that has been developed by Multi-Tech. This new
feature is ideal for those situations when a firewall is used in conjunction
with a MultiVOIP or when the use of dynamic IP address assignment is
necessary. Using SPP allows your voice traffic to pass through your firewall
by opening a single UDP port. Models with SPP have two modes of operation
for IP address assignment. In direct mode, all MultiVOIP gateways would
have a static IP address assigned to them. In the registrar/client mode, one
MultiVOIP gateway would serve as the registrar with a static IP address and
all the other gateways would serve as the clients using dynamic IP addresses
that would in turn point to the registrar.
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
Communication Manager 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.
over the Internet or Intranet.By integrating voice and fax into your existing
data network, you can realize sub- stantial savings on inter-office long
distance toll charges. The MultiVOIP family is available in analog and digital
models ranging from one to 60 ports. MultiVOIP products connect directly
to phones, fax machines, modems, key systems, or a PBX to provide
real-time, toll-quality voice connections to any office on
your VOIP network.
