This manual is about Voice-over-IP products made by Multi-Tech
Systems, Inc. It describes two ISDN/BRI MultiVOIP
models MVP810ST and MVP410ST. The MVP810ST has four
ISDN/BRI interfaces and therefore eight ISDN B-channels; the
MVP410ST has two ISDN/BRI interfaces and therefore four ISDN Bchannels.
These MultiVOIP units can inter-operate with other contemporary
analog MultiVOIP units (MVP810, MVP410, MVP210, MVP130 &
FXS/FXO MultiVOIPs like the MVP130FXS, MVPFX2-2/4/8 and
MVPFXS-8/16/24), with contemporary digital T1/E1/ISDN-PRI
MultiVOIP units (MVP2410 and MVP3010), and with the earlier
generation of MultiVOIP products (MVP200, MVP400, MVP800,
MVP120, etc.)
The table below (on next page) describes the vital characteristics of the
various models described in this manual.
How to Use This Manual. In short, use the index and the examples.
When our readers crack open this large manual, they generally need
one of two things: information on a very specific software setting or
technical parameter (about telephony or IP) or they need help when
setting up phonebooks for their voip systems. The index gives quick
access to voip settings and parameters. It’s detailed. Use it. The best
way to learn about phonebooks is to wade through examples like those
in our chapters on T1 (North American standard) Phonebooks and E1
(Euro standard) Phonebooks. Note that we have chapters on both T1
phonebooks and E1 phonebook even though this manual is about
ISDN-BRI voip units. “T1” simply refers to North American telephony
standards, whereas “E1” refers to European telephony standards.

units,
The printed Quick Start Guide shipped with your MultiVOIP (and
included on the MultiVOIP product CD in electronic form) contains
quick setup information for a minimal voip configuration.
Finally, this manual is meant to be comprehensive. If you notice that
something important is lacking, please let us know.
Additional Resources. The MultiTech web site (www.multitech.com)
offers both a list of Frequently Asked Questions (the MultiVOIP FAQ)
and a collection of resolutions of issues that MultiVOIP users have

Introduction to ISDN-BRI MultiVOIPs
(MVP410ST & MVP810ST)
VOIP: The Free Ride. We proudly present Multi-Tech's MVP410ST/810ST generation of MultiVOIP Voice-over-IP Gateways. All of
these models allow voice/fax communication to be transmitted at no
additional expense over your existing IP network, which has ordinarily
been data only. To access this free voice and fax communication, you
simply connect the MultiVOIP to your telephone equipment and your
existing Internet connection. These ISDN Basic Rate Interface (ISDNBRI) MultiVOIPs inter-operate readily with T1 or E1 MultiVOIP units
(T1 and E1 MultiVOIP units can operate in ISDN Primary Rate Mode,
ISDN-PRI, as well).

Capacity. MultiVOIP model MVP810ST accommodates four ISDN-BRI
lines (eight B-channels) and model MVP410ST accommodates two
ISDN-BRI lines (four B-channels). Both of these MultiVOIP units have a
10/100Mbps Ethernet interface and a command port for configuration.
Mounting. Mechanically, the MVP410ST and MVP810ST MultiVOIPs
are designed for a one-high industry-standard EIA 19-inch rack
enclosure. The product must be installed by qualified service personnel
in a restricted-access area, in accordance with Articles 110-16, 10-17, and
110-18 of the National Electrical Code, ANSI/NFPA 70.
Phone System Transparency. These MultiVOIPs inter-operate with a
telephone switch or PBX, acting as a switching device that directs voice
and fax calls over an IP network. The MultiVOIPs have “phonebooks,”
directories that determine to who calls may be made and the sequences
that must be used to complete calls through the MultiVOIP. The
phonebooks allow the phone user to interact with the VOIP system just
as they would with an ordinary PBX or telco switch. When the
phonebooks are set, special dialing sequences are minimized or
eliminated altogether. Once the call destination is determined, the
phonebook settings determine whether the destination VOIP unit must
strip off or add dialing digits to make the call appear at its destination
to be a local call.

MultiVOIP User Guide Overview
H. 323, SIP, & SPP. Being H.323 compatible, the BRI MultiVOIP unit
can place calls to telephone equipment at remote IP network locations
that also contain H.323 compatible voice-over-IP gateways. It will
interface with H.323 software and H.323 gatekeeper units. H.323
specifications also bring to voip telephony many special features
common to conventional telephony. H.323 features of this kind that
have been implemented into the MultiVOIP include Call Hold, Call
Waiting, Call Identification, Call Forwarding (from the H.450 standard),
and Call Transfer (H.450.2 from H.323 Version 2). The fourth version of
the H.323 standard improves system resource usage (esp. logical port or
socket usage) by handling call signaling more compactly and allowing
use of the low-overhead UDP protocol instead of the error-correcting
TCP protocol where possible.
The MultiVOIP is also SIP-compatible. (“SIP” means Session Initiation
Protocol.) However, H.450 Supplementary Services features can be
used under H.323 only and not under SIP.
SPP (Single-Port Protocol) is a non-standard protocol developed by
Multi-Tech. SPP is not compatible with the “Proprietary” protocol used
in Multi-Tech’s earlier generation of voip gateways. SPP offers
advantages in certain situations, especially when firewalls are used and
when dynamic IP address assignment is needed. However, when SPP
is used, certain features of SIP and H.323 will not be available and SPP
will not inter-operate with voip systems using H.323 or SIP.
Data Compression & Quality of Service. The BRI MultiVOIP unit
comes equipped with a variety of data compression capabilities,
including G.723, G.729, and G.711 and features DiffServ quality-ofservice (QoS) capabilities.
Gatekeepers. For voip systems built with MultiTech’s analog gateway
units, users can have a stand-alone gatekeeper (gatekeeper software
residing in separate hardware). Gatekeepers are optional but useful
within voip systems. The gatekeeper acts as the ‘clearinghouse’ for all
calls within its zone. MultiTech’s stand-alone gatekeeper software
performs all of the standard gatekeepers functions (address translation,
admission control, and bandwidth control) and also supports many
valuable optional functions (call control signaling, call authorization,
bandwidth management, and call management).
11
Overview MultiVOIP User Guide
Management. Configuration and system management can be done
locally with the MultiVOIP configuration software. After an IP address
has been assigned locally, other configuration can be done remotely
using the MultiVOIP web browser GUI. (The default IP address for the
BRI MultiVOIP unit is 192.168.3.143.) Remote system management can
be done via the MultiVOIP web browser GUI. The MultiVOIP
configuration software pack is included on the Product CD and the web
browser accesses firmware in the MultiVOIP unit itself.
While the web GUI’s appearance differs slightly, its content and
organization are essentially the same as that of the Windows GUI
(except for logging).
The primary advantage of the web GUI is remote access for control and
configuration. The controller PC and the MultiVOIP unit itself must
both be connected to the same IP network and their IP addresses must
be known.
12
MultiVOIP User Guide Overview
Once you’ve begun using the web browser GUI, you can go back to the
MultiVOIP Windows GUI at any time. However, you must log out of
the web browser GUI before using the MultiVOIP Windows GUI.
Logging of System Events. MultiTech has built SysLog Server
functionality into the software of the MultiVOIP units. SysLog is a de facto standard for logging events in network communication systems.
The SysLog Server resides in the MultiVOIP unit itself. To implement
this functionality, you will need a SysLog client program (sometimes
referred to as a “daemon”). SysLog client programs, both paid and
freeware, can be obtained from Kiwi Enterprises, among other firms.
See www.kiwisyslog.com
. SysLog client programs essentially give you
a means of structuring console messages for convenience and ease of
use.
MultiTech Systems does not endorse any particular SysLog client
program. SysLog client programs by any qualified provider should
suffice for use with MultiVOIP units. Kiwi’s brief description of their
SysLog program indicates the typical scope of such programs. “Kiwi
Syslog Daemon is a freeware Syslog Daemon for the Windows
platform. It receives, logs, displays and forwards Syslog messages from
hosts such as routers, switches, Unix hosts and any other syslog
enabled device. There are many customizable options available.”
13
Overview MultiVOIP User Guide
Supplementary Telephony Services. The H.450 standard (an addition
to H.323) brings to voip telephony more of the premium features found
in PSTN and PBX telephony. MultiVOIP units offer five of these H.450
features: Call Transfer, Call Hold, Call Waiting, Call Name
Identification (not the same as Caller ID), and Call Forwarding. (The
first four features are found in the “Supplementary Services” window;
the fifth, Call Forwarding, appears in the Add/Edit Inbound
phonebook screen.) Note that the first three features are closely related.
All of these H.450 features are supported for H.323 operation only; they
are not supported for SIP or SPP.
ISDN BRI MultiVOIP Front Panel LEDs
LED Types. The MultiVOIPs have two types of LEDs on their front
panels:
(1) general operation LED indicators (for power, booting, and
ethernet functions), and
(2) channel operation LED indicators that describe the data traffic
and performance in each VOIP data channel.
Active LEDs. On the MVP810ST, there are four sets of ISDN-operation
LEDs. On the MVP410ST, there are two sets of ISDN-operation LEDs.
Each set contains one “D” LED and two sets of channel operation LEDs
(XMT and RCV).

After power up, the Boot LED will be on briefly while the
MultiVOIP is booting. It lights whenever the MultiVOIP is
booting or downloading a setup configuration data set.
FDX. LED indicates whether Ethernet connection is
half-duplex or full-duplex (FDX) and, in half-duplex
mode, indicates occurrence of data collisions. LED is
on constantly for full-duplex mode; LED is off
constantly for half-duplex mode. When operating in
half-duplex mode, the LED will flash during data
collisions.
LNK. Link/Activity LED. This LED is lit if Ethernet
connection has been made. It is off when the link is
down (i.e., when no Ethernet connection exists).
While link is up, this LED will flash off to indicate data
activity.
D-Channel Operation LEDs (one for each ISDN line)
D
ISDN D-channel & physical layer indicator. One “D”
LED for each ISDN-BRI connection. The “D” LED is
off when the BRI physical layer is de-activated.* It
flashes when a connection is being established on the
physical layer. It is on when the physical layer has
been activated. It flickers to indicate D-channel traffic.
*If the voip is running in terminal mode and its BRI
line is unplugged, the D LED goes off. However, if the
voip is running in network mode and its BRI line is
unplugged, its LED will flash at regular interval.
B-Channel Operation LEDs (one for each B-channel)
XMT
RCV
Transmit. This indicator blinks when voice packets
are being transmitted onto the B-channel.
Receive. This indicator blinks when voice packets
are being received on the B-channel.

Overview MultiVOIP User Guide
Computer Requirements
The computer on which the MultiVOIP’s Windows configuration
program is installed must meet these requirements:
•must be IBM-compatible PC with MS Windows operating
system;
•must have an available COM port for connection to the
MultiVOIP.
However, this PC does not need to be connected to the MultiVOIP
permanently. It only needs to be connected when local configuration
and monitoring are done.
The MultiVOIP can also be configured and monitored using the
MultiVOIP web-based configuration program. In this case, the
command computer does not need to be an IBM-compatible PC nor
does it need to be running a Microsoft Windows operating system. The
MultiVOIP web-based configuration program can be accessed by a web
browser running on any operating system (for example, Linux,
MacIntosh, or IBM-compatible computers). To access the MultiVOIP by
its web GUI, use the IP address 192.168.3.143, which is the MultiVOIP’s
default IP address. (For permanent use, you will need to change the IP
address from the default value to a value that fits your voip system.)

Phone/IP Details *Absolutely Needed*
Before Starting the Installation
The MultiVOIP will interface with both the IP network and the phone
system. You must gather information about the IP network and about
the phone system so that the MultiVOIP can be configured to operate
with them properly. A summary of this configuration information
appears on page 24 (“Config Info CheckList”).

When you’re done installing the MultiVOIP, you’ll want to confirm that
it is configured and operating properly. To do so, it’s good to have
another voip that you can call for testing purposes. You’ll want to
confirm end-to-end connectivity. You’ll need IP and telephone
information about that remote site.
If this is the very first voip in the system, you’ll want to coordinate the
installation of this MultiVOIP with an installation of another unit at a
remote site.
Identify VOIP Protocol to be Used
Will you use H.323, SIP, or SPP? Each has advantages and
disadvantages. Although it is possible to mix protocols in a single
VOIP system, it is highly desirable to use the same VOIP protocol for
all VOIP units in the system. SPP is a non-standard protocol developed
by Multi-Tech. SPP is not compatible with the “Proprietary” protocol
used in Multi-Tech’s earlier generation of voip gateways.

Voip Placement & PC Settings MultiVOIP Quick Start Instructions
Placement
Mount your MultiVOIP in a safe and convenient location where cables
for your network and phone system are accessible. Rack-mounting
instructions are in Chapter 3: Mechanical Installation & Cabling of the User
Guide.
Command/Control Computer Setup (Specs & Settings)
The computer used for command and control of the MultiVOIP
(a) must be an IBM-compatible PC,
(b) must use a Microsoft operating system,
(c) must be connected to your local network (Ethernet) system, and
(d) must have an available serial COM port.
The configuration tasks and control tasks the PC will have to do with
the MultiVOIP are not especially demanding. Still, we recommend
using a reasonably new computer. The computer that you use to
configure your MultiVOIP need not be dedicated to the MultiVOIP
after installation is complete.
COM port on controller PC. You’ll need an available COM port on the
controller PC. You’ll need to know which COM port is available for use
with the MultiVOIP (COM1, COM2, etc.). If your command computer
has only USB2.0 ports and no serial ports, you will need a USB2.0-toserial adaptor.
Work-Around Allowing Use of Web GUI Only. The default IP
address of the MultiVOIP unit as shipped from the factory is
192.168.3.143. By installing the up-to-date Java program from the
MultiVOIP CD, temporarily resetting the IP address of the command
computer to 192.168.3.x, and connecting both to the same physical
Ethernet network, the MultiVOIP unit’s built-in- web GUI can be
contacted and its IP address can be set as needed. If this is done, all
subsequent configuration can be done using the MultiVOIP web GUI
and the command computer would not need a serial COM port.
Therefore, in the case of a computer lacking a serial port, no USB2.0-toserial adaptor would be needed. However, under such an
arrangement, the command computer would remain unable to use the
MultiVOIP Windows GUI because contact with the Windows GUI
requires either a COM port or the USB2.0-to-serial adaptor
arrangement. (If you use this work-around, you must be sure to re-set
your command PC to its original IP address afterwards.)
For more details, see Chapter 4: Software Installation in this manual.
1. MultiVOIP must be properly cabled. Power must be turned on.
