MultiVOIP Quick Start Guide

Introduction

The MultiVOIP model MVP120 enables FXO-only analog voice

and fax communication over an IP network. Multi-Tech’s new

voice/fax gateway technology allows voice and fax

communication to ride, with no additional expense, over your

existing IP network, which has traditionally been data-only. To

access this free voice and fax communication, all you have to

do is connect the MultiVOIP to your telephone equipment, 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 MVP120 has one independent voice/fax 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 online Help.

Figure 1. MultiVOIP

Introduction

Overview

Install Y our MultiVOIP

The basic steps of installing your MultiVOIP network involve

unpacking the units, connecting the cables, and configuring

the units using the included management software (MultiVOIP

Configuration). The recommended installation process

includes three phases that, when completed, result in a fully

functional Voice Over IP network. A general description of

each phase is provided below, and detailed instructions follow

throughout the rest of this section.

Configure and Install Your Host MultiVOIP

First, the VOIP administrator configures the MultiVOIP

designated as the “Host” unit. This includes the assignment of

a unique LAN IP address, subnet mask, and Gateway IP

address. Once the VOIP is configured, the administrator

builds the Phone Directory Database that will reside with the

Host unit.

Configure Your Client MultiVOIPs

Once installation has been completed, the administrator

moves on to configure the MultiVOIPs designated as “Client”

units. Again, this includes the assignment of unique LAN IP

addresses, subnet masks, and a Gateway IP address. When

this is done, the Phone Directory Database option is set to

Client, and the IP address of the Host MultiVOIP is entered.

Once all Client units are configured, the VOIP network can be

deployed.

Introduction

Deploy the VOIP Network

The final phase of the installation is deployment of the

network. Through the first two phases, the VOIP administrator

controls configuration, so when the Client MultiVOIPs are sent

to their remote sites, the remote site administrators need only

to connect the units to their LAN and telephone equipment. A

full Phone Directory Database (supplied by the Host

MultiVOIP) will be loaded into their unit within minutes of being

connected and turned on.

The final task of the VOIP Administrator is to develop the VOIP

Dialing Directory based on the Phone Directory Database and

telephone numbers of the interfacing telephone equipment, at

which point, a VOIP user can call any person on the VOIP

network.

MultiVOIP Quick Start Guide

Unpacking Your MultiVOIP

Safety Warnings

Caution: Danger of explosion if battery is incorrectly replaced.

A lithium battery on the voice/fax channel board provides

backup power for the time keeping capability . The battery has

an estimated life expectancy of ten years. When the battery

starts to weaken, the date and time may be incorrect. If the

battery fails, the board must be sent back to Multi-Tech

Systems for battery replacement.

Note: The Command and Ethernet ports are not designed to

be connected to a Public Telecommunication Network. FXO

can be connected to a PBX/FXO port or PSTN Network.

Cabling Your MultiVOIP

Cabling your MultiVOIP involves making the proper

connections for power, the command port, the FXO/PBX or

PSTN system, and the Internet. Figure 3 shows the back

panel connectors and the associated cable connections. The

following procedure details the steps necessary for cabling

your MultiVOIP.

1. Connect the power supply to a live AC outlet, and then connect it to the MultiVOIP as shown in Figure 3.
