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.

Overview
Install Your 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 VOIPAdministrator 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.

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.

15. Check with your in-house phone personnel to verify
whether your local PBX dial signaling is Pulse or DTMF
(tone). Select the Regeneration option accordingly.
In the Max Dial Digits box, enter the maximum number of
digits allowed when dialing a phone number. The default
number is 5. In the Inter Digit Time option defines the
maximum amount of time between dialed digits that the
unit will wait before mapping the dialed digits to an entry in
the Phone Directory Database. If too much time elapses
between digits, the wrong number will be mapped and you
will hear a rapid busy signal. If this happens, hang up and
dial again. The default setting is 2 seconds.
In the Flash Hook Timer box, enter the amount of time for
the duration of the flash hook signals output on the FXO
interface. The default setting is 600 milliseconds.

MultiVOIP Quick Start Guide

For FXO-to-FXO communications, you can enable a
specific FXO Disconnect: Fix Current Loss, Tone
Detection, or Silence Detection. Check with your in-
house phone personnel to verify the type of disconnect to
use. If Current Loss is checked, the VOIP will hangup
when it detects a loss of current on the FXO/phone port.
For Tone Detection, select from the drop down list box
one or two tones that will cause the line to disconnect. The
person hanging up the call must then press the key or
keys that produce those tones to hang up a call. For
Silence Detection, select One Way or Two Way. Then
enter in the Silence Timer box the number of seconds of
silence before disconnect. The default value of 15 seconds
may be shorter than desired for your application.
To dedicate the local voice/fax channel to a remote voice/
fax channel, (so you will not have to dial the remote
channel) select the Auto Call Enable check box. Enter
the phone number of the remote VOIP in the Phone
Number box.
16. The Voice/Fax tab displays the parameters for the voice
gain, DTMF (Dual Tone Multi-Frequency) gain, voice
coder, faxing, and advanced features such as Silence
Compression, Echo Cancellation, and Forward Error
Correction.

Configuring the Host MultiVOIP
To change the voice coder, select the new voice coder
entry from the Voice Coder list. If you change the voice
coder, ensure that the same voice coder is used on the
voice/fax channel you are calling. Otherwise, you will get a
busy signal.
Note: If Automatic Coder is selected, enter the bandwidth
in the Max Bandwidth box. Check with your Network
Administrator to determine available bandwidth.
You can set up the Input Gain and Output Gain so that
the volume can be increased or decreased. Input gain
modifies the level of the audio coming into the voice
channel before it is sent over the Internet to the remote
MultiVOIP. Output gain modifies the level of the audio
being output to the device attached to the voice channel.
Make your selections from the Input and Output drop-
down lists in the Voice group. The valid range is +31dB to
–31dB with a recommended/default value of 0.

17. The Fax group enables you to select the maximum baud
rate for faxes and adjust the fax volume. If you do not plan
to send or receive faxes on a given voice/fax channel, you
can disable faxes in the Fax group.
18. The Miscellaneous group lets you set voice/fax advanced
features by clicking (checking) Silence Compression,
Echo Cancellation, or Forward Error Correction.
The Silence Compression option defines whether silence
compression is enabled for the voice channel. If silence
compression is enabled, the MVP120 will not transmit
voice packets when silence is detected, thereby reducing
the amount of network bandwidth used by the voice
channel.
The Echo Cancellation option defines whether echo
cancellation is enabled for the voice channel. If echo
cancellation is enabled, the MVP120 will remove echo
which improves the quality of sound.
The Forward Error Correction (FEC) option defines
whether forward error correction is selected for the voice
channel. The FEC feature allows some of the voice
packets that were corrupted or lost to be recovered. FEC
adds an additional 50% overhead to the total network
bandwidth consumed by the voice channel.
