Introduction
Welcome to Multi-Tech's stand-alone Voice/IP Gateway, the
MultiVOIP, model MVP110. The MultiVOIP 110 allows analog
voice and fax communication over an IP network. Multi-Tech’s
voice/fax gateway technology allows voice/fax communication
to be transmitted, 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 110 to your telephone equipment,
and then to your existing Internet connection. Once
configured, the MultiVOIP 110 then allows voice and fax to
travel down the same path as your traditional data
communications.
The MultiVOIP 110 supports the H.323 standards-based
protocol enabling your MultiVOIP 110 to communicate with
other third-party VOIP Gateways or other endpoints that
support the H.323 protocol, such as Microsoft NetMeeting®.
The H.323 standard defines how endpoints make and receive
calls, how endpoints negotiate a common set of audio and
data capabilities, and how information is formatted and sent
over the network. This version of the software also supports
communication with a Multi-Tech MVPGK1 Gatekeeper or an
optional 3rd party H.323 Gatekeeper which, when enabled,
maintains its own phonebook database, pre-registers all users,
controls the bandwidth, and handles all conferencing issues
such as transferring of calls.

Installing Your MultiVOIP 110
The basic steps of installing your MultiVOIP 110 network
involve unpacking the units, connecting the cables, and
configuring the units using management software (MultiVOIP
110 Configuration). This process results in a fully functional
Voice Over IP network. Abrief description is provided below
with detailed instructions provided later.
Installing and Configuring Your MultiVOIP 110
The VOIP administrator must first install the MultiVOIP 110
software and then configure each MultiVOIP 110 for its specific
function. During the configuration process, it’s important to
note that the Phone Directory Database is configured
differently depending on whether or not you have Gatekeeper
support on your VOIP network.
If your VOIP network supports an H.323 Gatekeeper, you
must register all H.323 endpoints with the Gatekeeper. The
procedure for doing this is explained in the section
“Registering with a Gatekeeper Phone Directory.”
If your VOIP network does not have Gatekeeper software or
the Gatekeeper software is not enabled, then you must build a
proprietary phonebook with a “Host” MultiVOIP 110 and
“Client” MultiVOIP 110s. The “Host” unit includes the
assignment of a unique LAN IP address, subnet mask, and
Gateway IP address; as well as the selection of appropriate
channel interface type for each of the Voice/Fax channels.
Once all connections have been made, the VOIP administrator
configures the unit and builds the Phone Directory Database
that will reside in the Host unit.
After the “Host” MultiVOIP 110 is configured, the administrator
moves on to configure the MultiVOIP 110s designated as
“Client” units. Again, unique LAN IP addresses, subnet
masks, and Gateway IP addresses are assigned, and each
Voice/Fax channel is configured for the appropriate channel
interface type. When this is done, the Phone Directory

7
Introduction
Database option is set to Client, and the IP address of the
Host MultiVOIP 110 is entered. Once all Client units are
configured, the process moves on to the “Deploying the VOIP
Network” section.
Deploying the VOIP Network
The final phase of the installation is deployment of the
network. When the remote MultiVOIP 110s are sent to their
remote sites, the remote site administrators need only connect
the units to their LAN and telephone equipment.Afull Phone
Directory Database (supplied by the Host MultiVOIP 110
Proprietary Phonebook will be loaded into their units within
minutes of being connected and powered up.
For remote VOIPs that were configured with the Gatekeeper
option enabled, each MultiVOIP 110 will be registered with the
Gatekeeper (the Gatekeeper phonebook directory is NOT
downloaded to the remote units).

configured differently depending on whether or not the
Gatekeeper function is available and enabled on the Phone
Directory Database dialog box.
11. The IP Protocol Default Setup dialog box displays.
The default Frame Type is TYPE_II. If this does not match

MultiVOIP Quick Start Guide
16
your IP network, change the Frame Type by selecting
SNAP from the Frame Type list. The available Frame
Type choices are TYPE_II and SNAP.
12. In the Ethernet group, enter the IP Address, Subnet
Mask, and Gateway Address unique to your IP LAN. The
IP address is the unique LAN IP address that is assigned
to the MultiVOIP 110, and the Gateway address is the IP
address of the device connecting your MultiVOIP 110 to
the Internet. Click OK when you are finished.
13. The Channel Setup dialog box displays. The four tabs in
this dialog box define the channel interface, voice/fax
parameters, billing/miscellaneous parameters, and
regional telephone parameters.
The Inter Digit Time option defines the maximum amount
of time 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, and the wrong
numbers are mapped, you will hear a rapid busy signal. If

17
Configuring the MultiVOIP
this happens, hang up and dial again. The default setting
is 2 seconds.
14. The Ring Count FXS box enables you to set the
maximum number of rings output on the FXS interface
before hanging up and releasing the line to another call.
The default setting is 8 rings.
Note: Zero (0) means no rings - caller hears a busy tone.
15. 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.
16. You can set up the input and output voice gain so that the
volume can be increased or decreased. Input gain
modifies the level of the audio coming in to the voice
channel before it is sent over the Internet to the remote
MultiVOIP 110. Output gain modifies the level of the audio
being output to the device attached to the voice channel.

MultiVOIP Quick Start Guide
18
Make your selections from the Input and Output drop-
down lists in the Voice Gain group. The valid range is
+31dB to –31dB with a recommended/default value of 0.
You can also set up the DTMF gain (or output level in
decibels - dB) for the higher and lower frequency groups
of the DTMF tone pair. Make your selections in the drop-
down lists in the DTMF Gain group. When DTMF Out of
Band is checked, the unit reproduces the DTMF tones
instead of passing them through.
Note: Only change the DTMF gain under the direction of
Multi-Tech Technical Support supervision.
17. To change the voice coder, first select the channel from
the Select Channel list then select the Manualoption in
the Coder group. Select the appropriate coder, from the
Selected Coder list.
If you changed the voice coder, ensure that the same
voice coder is used on the voice/fax channel you are
calling; otherwise, you will always get a busy signal.
Note: If you allow the Coder to be selected automatically,
then you need to select the Max Bandwidth from the
drop-down list. Check with your NetworkAdministrator to
determine how much bandwidth is available.
18. The Fax group enables you to send/receive faxes on the
selected voice/fax channel. You can set the maximum
baud rate for faxes and the fax volume in the two drop-
down lists and change the jitter value in milliseconds.
When receiving fax packets from a remote MultiVOIP 110,
it is possible for individual packets to be delayed or
received out of order due to traffic conditions on the
network. To compensate for this effect, the MultiVOIP 110
uses a Jitter Buffer. The Jitter Value box allows the
MultiVOIP 110 to wait a user-definable period of time, in

19
Configuring the MultiVOIP
milliseconds, for delayed or out of order fax packets. The
range of allowable Jitter Values is 0 to 400 with a default of
400 milliseconds.
If you do not plan to send or receive faxes on a given
voice/fax channel, you can disable faxes in the Fax group.
19. You can enable the voice/fax advanced features by
clicking (checking) the silence compression, echo
cancellation, or forward error correction options.
The Silence Compression option defines whether silence
compression is enabled (checked) for this voice channel. If
silence compression is enabled, the MultiVOIP 110 will not
transmit voice packets when silence is detected, thereby
reducing the amount of network bandwidth that is being
used by the voice channel.
The Echo Cancellation option defines whether echo
cancellation is enabled (checked) for this voice channel. If
echo cancellation is enabled, the MultiVOIP 110 will
remove echo which improves the quality of sound.
The Forward Error Correction (FEC) option defines
whether forward error correction is enabled (checked) for
this 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.
20. The Billing/Misc tab displays the parameters for auto call,
automatic disconnection, billing options, and dynamic jitter
buffer.

MultiVOIP Quick Start Guide
20
If you want to dedicate a local voice/fax channel to a
remote voice/fax channel (so you will not have to dial the
remote channel), click the Auto Call Enable option in the
Auto Call group. Then enter the phone number of the
remote MultiVOIP 110 in the Phone Number box.
21. The Automatic Disconnection group provides three
options to be used singly or in combination.
The Jitter Value defines the average inter-arrival packet
deviation (in milliseconds) before the call is automatically
disconnected. Jitter is the inter-arrival packet deviation
(phase shift of digital pulses) over the transmission
medium that causes voice breakup which can be
particularly disruptive to voice communications. The
default setting is 20 milliseconds.Ahigher value means
that the voice transmission will be more accepting of jitter.
Alower value will be less tolerant of jitter.
