							6 MultiVOIP 200 User Guide
Introduction
Welcome to Multi-Techs new voice/fax gateway, the MultiVOIP, model MVP200. The MultiVOIP
allows analog voice and fax communication over a traditional data communications/data networking
digital Internet. Multi-Tech’s new voice/fax gateway technology allows voice and fax communication
to ride, with no additional expense, over your existing communications Internet, which has
traditionally been data-only. To access this free voice and fax communication, all you have to do is
connect the MultiVOIP to a phone or to your existing in-house phone switch, and then to your existing
Internet connection. Once configured, the MultiVOIP then allows voice and fax to travel down the
same path as your traditional data communications.
The MVP200 is designed with two voice/fax channels (which offer three voice/fax interfaces on each
channel), a 10 Mbps Ethernet LAN interface, and a command port for configuration. System
management is provided through the command port using bundled Windows® software which
provides easy-to-use configuration menus and a comprehensive Help system.

							7 Chapter 1 - Introduction and Description
Preview of this Guide
This guide describes the MultiVOIP and tells you how to install and configure the unit. The
information contained in each chapter is as follows:
Chapter 1 - Introduction and Description
Chapter 1 describes the MultiVOIP. Front panel indicators, and back panel connector descriptions are
provided. In addition, a list of relevant specifications is provided at the end of the chapter.
Chapter 2 - Installation
Chapter 2 provides information on unpacking and cabling your MultiVOIP. The installation procedure
describes each cable connection.
Chapter 3 - Software Loading and Configuration
Chapter 3 provides instructions for software loading and initial configuration. The MultiVOIP software
disks are Windows® based. Later chapters, as well as the on-line Help, describe the MultiVOIP
software in more detail.
Chapter 4 - MultiVOIP Software
Chapter 4 describes the MultiVOIP software package designed for the Windows ® environment. This
chapter describes the software from an applications standpoint, and in so doing, not every screen is
shown, nor is each field within a screen defined. For explanations and parameters of each field within
a dialog box, refer to the Help.
Chapter 5 - Remote Configuration and Management
Chapter 5 provides procedures for changing the configuration of a remote MultiVOIP. Remote
configuration enables you to change the configuration of a unit by simply connecting two modems
between the two MultiVOIPs and remotely controlling the unit. Chapter 5 also describes typical client
applications (i.e., Telnet and Web-based management) used for remote configuration of the
MultiVOIP.
Chapter 6 - Warranty, Service and Tech Support
Chapter 6 provides instructions on getting service for your MultiVOIP at the factory, a statement of
the limited warranty, information about our Internet presence and user bulletin board service, and
space for recording information about your MultiVOIP prior to calling Multi-Tech’s Technical Support.

Typical Application
Before Voice Over IP (VOIP), voice over the Internet, a corporate office had a data connection to the
Internet and a voice connection to the public telephone network. With VOIP, the two networks can be
tied together.  To accomplish this, a MultiVOIP is connected between the public telephone network
and the data network.  A typical application for a MultiVOIP is shown in Figure 1-2.

Figure 1-2. Typical VOIP Application
Now, to set up the VOIP network, a MultiVOIP at the corporate office is connected between the data
network and the corporate telephone switch (PBX). To connect the MultiVOIP to the data network, an
Ethernet cable is connected to the Ethernet port on the MultiVOIP and the other end of the cable is
plugged into a hub on the data network. On the phone side, two special adapter cables are
connected to the FXO jacks on the back of the MultiVOIP and run to two station lines on the phone
switch.  These two lines on the PBX occupy phone extensions 4124 and 4125.
To set up a MultiVOIP at the remote branch office, the Ethernet jack on the MultiVOIP is connected to
the hub and two special adapter cables are connected between the FXS jacks on the MultiVOIP and
two analog phones.
To configure a MultiVOIP, the COM port of a PC is connected to the Command port on the MultiVOIP.
Configuration software is loaded on to your PC and your unique LAN parameters are established.
The configuration software is based on a standard Windows Graphical User Interface (GUI) which
simplifies your selection process to a single parameter group within a dialog box.  For example, your
LAN IP parameters are contained on a single dialog box.  You can configure the IP address and
mask for the MultiVOIP, and the gateway address for the corporate router, on the same dialog box.
Once the LAN parameters are established, you can set up the voice channel parameters.
The unique feature here is that both channels do not have to be configured the same way.  One
channel could be connected to an extension line off the phone switch and the other channel
connected directly to your fax machine.  In this situation, you would use the FXS interface which has
two options -- loop start and ground start.  Loop start is generally the correct interface to use.  
						

							9 Chapter 1 - Introduction and Description
If you want a user to be able to call into a facility and then use the local phone capability to dial out to
the public phone network, you can choose either the FXO or E&M interface.  If you chose the FXO
interface, you can connect to the station side of your phone switch and be able to use all the features
of your local phone system.  If you want to call out on the local phone network while you are at a
remote branch office, you would dial the MultiVOIP at the corporate facility and then dial an outside
line to access the local phone network.
If you use the E&M interface, you have more control over call management. The E&M connection
uses the trunk side of the phone switch; therefore, to access a trunk line, you would dial the trunk’s
access number instead of an extension number.  Also, the E&M interface has five signaling types that
are supported by the MultiVOIP.
Once you have mapped out your phone and Internet/Intranet connections, you can build your VOIP
phone directory database that connects your MultiVOIPs together.  From the phone directory
database you can construct a VOIP phone book and a VOIP dialing directory. One phone directory
database is all that is needed for a VOIP network.  This database can be built at one site and then
distributed to other sites.  The database ties the voice/fax channels to phone equipment and the
ethernet port to your local area network.   
						

							10 MultiVOIP 200 User Guide
Before you construct the phone directory database, you must establish the Master-Slave relationship
between MultiVOIPs, which enables one multiVOIP (the “Master”) to control the database.  The
database defines each phone number that can be dialed on the VOIP network.  Each phone number
entry in the database identifies a phone connection.  For example, Station Phone Number 101 is at
the corporate office.  This phone number is connected to voice/fax channel 1 on the corporate office
MultiVOIP.  Voice/fax channel 1 is connected to extension 4124 on the corporate phone switch.  So if
a person in the corporate facility wants to access the VOIP network, they would merely dial extension
4124. However, if someone at the remote branch office wants to access the corporate phone system,
they have to dial Station Phone Number 101.
From the phone directory database you can build your VOIP dialing directory.  For example, a
corporate user picks up a phone in his/her office and dials extension 4124. This connects them to
channel 1 on the  corporate MultiVOIP.  A second dial tone is heard, and they then dial VOIP
extension 301 which connects them to the remote branch office and enables a voice conversation to
take place over the VOIP network.
Similarly, a remote branch office employee can pick up the phone at 301 and dial VOIP extension
102.  This routes the call to the corporate office MultiVOIP where a second dial tone is heard; the
remote branch office employee then dials extension 4122 and a conversation can take place between
the two phones.
To call fromCall Process

number (e.g., 4124 or 4125). Upon hearing
