Introduction
Welcome to Multi-Tech's stand-alone Voice/IP Gateway, the
MultiVOIP model MVP110. The MVP110 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 MVP110 to your telephone equipment, and then to
your existing Internet connection. Once configured, the
MVP110 then allows voice and fax to travel down the same
path as your traditional data communications.
The MVP110 supports the H.323 standards-based protocol
enabling your MVP110 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 endpoints, controls the
bandwidth, and handles all conferencing issues such as
transferring of calls.

Installing Your MVP110
The basic steps of installing your MVP110 network involve
unpacking the units, connecting the cables, and configuring
the units using management software (MVP 110
Configuration). This process results in a fully functional Voice
Over IP network. A brief description is provided below with
detailed instructions provided later.
Installing and Configuring Your MVP110
The VOIP administrator must first install the MVP110 software
and then configure each MVP110 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 “Master” MultiVOIP and “Slave”
MultiVOIPs. The “Master” unit includes the assignment of a
unique LAN IP address, subnet mask, and Gateway IP
address. Once all connections have been made, the VOIP
administrator configures the unit and builds the Phone
Directory Database that will reside in the Master unit.
After the “Master” MultiVOIP is configured, the administrator
moves on to configure the MultiVOIPs designated as “Slave”
units. Again, unique LAN IP addresses, subnet masks, and
Gateway IP addresses are assigned, and the Voice/Fax
channel is configured for the FXS Loop interface type. When
this is done, the Phone Directory Database option is set to
Slave, and the IP address of the Master MVP 110 is entered.

7
Introduction
Once all Slave 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 MultiVOIPs are sent to their remote
sites, the remote site administrators need only connect the
units to their LAN and telephone equipment. A full Phone
Directory Database Proprietary Phonebook, supplied by the
Master MultiVOIP 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 will be registered with the
Gatekeeper. The Gatekeeper phonebook directory is NOT
downloaded to the remote units.

The default Frame Type is TYPE_II. If this does not match
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 assigned to the
MVP110. The Gateway address is the IP address of the
device connecting your MVP110 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.
The Message Waiting Light check box must be selected
on the originating and answering voice channel. This
enables the number dialed to connect you to the
appropriate voice channel, then output that number on the
voice channel. This feature does not work FXS to FXS.
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

MultiVOIP Quick Start Guide
18
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. 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 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, select the Manual option 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 the Coder is selected automatically,enter the
bandwidth in the Max Bandwidth box. Check with your
Network Administrator to determine how much bandwidth
is available.
18. The Fax group enables you to send/receive faxes on the
voice/fax channel. You can set the maximum baud rate for
faxes, the fax volume, and change the jitter value in
milliseconds.
When receiving fax packets from a remote MVP110, it is
possible for individual packets to be delayed or received

19
Configuring the MultiVOIP
out of order due to traffic conditions on the network. To
compensate for this effect, the MVP110 uses a Jitter
Buffer. The Jitter Value box allows the MVP110 to wait a
user-definable period of time, in 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 the 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 for the voice channel. If silence
compression is enabled, the MVP110 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 MVP110 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.

20. The Billing/Misc tab displays the parameters for auto call,
automatic disconnection, billing options, and dynamic jitter
buffer.
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 MVP110 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. A higher value means
that the voice transmission will be more accepting of jitter.
A lower value will be less tolerant of jitter.
