This manual is about Voice-over-IP products made by Multi-Tech
Systems, Inc. It describes three analog MultiVOIP units with SIPsurvivability features, models MVP810SS, MVP410SS, and MVP210SS
These MultiVOIP units can inter-operate with other contemporary
analog MultiVOIP units (MVP130, MVP130FXS, MVP210, MVP410, and
MVP810), with contemporary BRI MultiVOIP units (MVP410ST &
MVP810ST), 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 in the MultiVOIP product family.
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. 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
encountered (these are Troubleshooting Resolutions in the searchable
Knowledge Base).

Introduction to Analog MultiVOIPs
with SIP Survivability Features
(MVP-210SS/410SS/810SS)
VOIP: The Free Ride. We proudly present Multi-Tech's MVP210SS/410SS/810SS MultiVOIP Voice-over-IP Gateways. These three
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 analog MultiVOIPs inter-operate
readily with T1 or E1 MultiVOIP units.

MultiVOIP User Guide Overview
Capacity. MultiVOIP model MVP810SS is an eight-channel unit, the
model MVP410SS is a four-channel unit, and the MVP210SS is a twochannel unit. All three of these MultiVOIP units have a 10/100Mbps
Ethernet interface and a command port for configuration.
SIP Survivability. The MVP210SS, MVP410SS and MVP810SS have a
special capacity that reaches beyond ordinary voip functionality: they
can direct call traffic for phones connected to their channels or phones
connected to channels of other SIP gateways in the network (this is
basic SIP server functionality). The MVP-SS unit would normally be
located at a remote branch office served by a central SIP server (PBX) at
the organization’s main office. The MVP-SS is intended as a backup in
case the network’s main SIP server (often a PBX) fails or loses contact
with the group of gateways at the remote branch office. If the main SIP
server fails, the MVP-SS allows branch office phone users to call each
other and access the PSTN via POTS lines or a key telephone system.

A single MVP210SS, MVP410SS or MVP810SS can provide SIP server
functionality for as many as 500 other voip gateways. However, the
number of phone lines that these units support (4 for the MVP410SS; 8
13
Overview MultiVOIP User Guide
for the MVP810SS) constitutes a practical limitation on their capacity to
support PSTN access for other gateways. Systems must be scaled to
match required capacity by including additional MultiVOIP-SS units.
Mounting. Mechanically, the MVP410SS and MVP810SS 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.
Voip Protocol. The MVP-SS units use the SIP protocol only. (“SIP”
means Session Initiation Protocol.)
Data Compression & Quality of Service. The analog 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.
PSTN Failover Feature. The MultiVOIP can be programmed to divert
calls to the PSTN temporarily in case the IP network fails.
RADIUS Support. Inter-operation with a RADIUS server allows for
call accounting (especially for billing) on a voip system. The MultiVOIP
supports inter-operation with RADIUS servers for the RADIUS
accounting function (but not the RADIUS authentication function).
STUN Support. The STUN protocol (Simple Traversal of UDP through
NATs (Network Address Translation)) assists with the packet routing
functions of devices behind NAT firewalls or routers. The MultiVOIP
supports inter-operation with STUN servers and NATs (SIP based
environment only).
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. Remote system management
can be done with the MultiVoipManager SNMP software or via the
14
MultiVOIP User Guide Overview
MultiVOIP web browser GUI. All of these control software packages
are included on the Product CD.
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).
15
Overview MultiVOIP User Guide
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.
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.”

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 both the MVP410SS and MVP810SS, there are eight
sets of channel-operation LEDs. However, on the MVP410SS, only the
lower four sets of channel-operation LEDs are functional. On the
MVP810SS, all eight sets are functional.
Figure 1-4. MVP-410SS/810SS LEDs
Similarly, the MVP210 has the general-operation indicator LEDs and
two sets of channel-operation LEDs, one for each channel.

MultiVOIP User Guide Overview
Computer Requirements
The computer on which the MultiVOIP’s 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. Nearly all configuration and monitoring
functions can be done remotely via the IP network.

Identify Remote VOIP Site to Call
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 MVP-SS Unit’s Role in SIP VOIP System
The MVP210-SS/410-SS/810-SS unit always uses the SIP protocol.
However, the MVP-SS units are equipped to play an additional role in
the voip system -- the role of a SIP server. And as a SIP server, the
MVP-SS unit can operate in either “stand-alone” mode or “SIP
survivability” mode.
Stand-Alone Mode. The MVP-SS unit can function as a stand-alone SIP
server that controls the flow of phone traffic to lines connected to
gateways that are registered with the MVP-SS unit. This stand-alone
capability allows the MVP-SS to operate with ‘smart’ SIP phones. Such
smart SIP phones can choose the SIP server under which they operate
and, consequently, can be controlled by either the SIP-based PBX or by
the MVP-SS.
SIP Survivability Mode. The MVP-SS unit can function as a back-up SIP
server that performs SIP server functions when/if the network’s main
SIP server fails or loses contact with the subnetwork in which the
MVP-SS unit is placed.

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.).
