MultiVOIP Quick Start Guide
Introduction
Welcome to Multi-Tech's new stand-alone Voice/IP Gateway,
the MultiVOIP, model MVP200. The MultiVOIP 200 allows
analog voice and fax communication over an IP network. MultiTech’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 200 to your telephone
equipment, and then to your existing Internet connection. Once
configured, the MultiVOIP 200 then allows voice and fax to
travel down the same path as your traditional data
communications.
The MultiVOIP 200 supports the H.323 standards-based
protocol enabling your MultiVOIP 200 to communicate with
other third-party VOIP Gateways or other endpoints that
support the H.323 protocol (e.g., 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.

Introduction
The MVP200 has two independent voice/fax channels (each
with three voice/fax interfaces), 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 comprehensive on-line Help.

MultiVOIP Quick Start Guide
Installing Your MultiVOIP 200
The basic steps of installing your MultiVOIP 200 network
involve unpacking the units, connecting the cables, and
configuring the units using management software (MultiVOIP
200 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 MultiVOIP 200
The VOIP administrator must first install the MultiVOIP 200
software and then configure each MultiVOIP 200 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 200 and
“Client” MultiVOIP 200s. 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 200 is configured, the administrator
moves on to configure the MultiVOIP 200(s) 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 Database option
6
Introduction
is set to Client, and the IP address of the Host MultiVOIP 200
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 200s 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 (supplied by the Host MultiVOIP 200
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 200 will be registered with the
Gatekeeper (i.e., the Gatekeeper phonebook directory is NOT
downloaded to the remote units).

3. Connect a network cable to the Ethernet 10Base-T
connector on the back of the MultiVOIP 200. Connect the
other end of the cable to your network.
4. If you are connecting a station device; e.g., analog
telephone, fax machine, or Key Telephone System (KTS)
to your MultiVOIP 200, connect the smaller end of a
special adapter cable (supplied) to the Voice/Fax Channel
1 FXS connector on the back of the MultiVOIP 200 and the
other end to the station device.
If you are connecting a PBX extension to your MultiVOIP
200, connect the smaller end of a special adapter cable
(supplied) to the Voice/Fax Channel 1 FXO connector on
the back of the MultiVOIP 200 and the other end to the
PBX extension.
If you are connecting an E&M trunk from a telephone
switch to your MultiVOIP 200, connect one end of an RJ45 cable (not supplied) to the Voice/Fax Channel 1 E&M
connector on the back of the MultiVOIP 200 and the other
end (8 spade lugs or 8 wires to connect directly to the
punch-down block) to the PBX trunk card.
Note: For customers building their own E&M connector,
App. B of the User Guide has a pinout diagram showing
the E&M back panel connector on the MultiVOIP 200.
5. Repeat step 4 to connect the remaining phone equipment
to each Voice/Fax Channel on your MultiVOIP 200.
6. Turn on power to the MultiVOIP 200 by setting the power
switch on the back panel to the 1 (up, On) position. Wait for
the Boot LED on the MultiVOIP 200 to go Off before
proceeding. This may take a couple of minutes.
If you need to change the E&M Jumper Block positioning,
refer to the following section; otherwise, proceed to the
Software Loading section to load MultiVOIP 200 software.

Cabling
E&M Jumper Block Positioning Procedure
Each voice/fax channel on the MultiVOIP 200 has a separate
E&M jumper block located near the jacks on the back panel of
the MultiVOIP 200. Each jumper block has 8 pairs of pins with
a jumper plug on three adjacent pairs of pins. The jumper plug
must be centered on the E&M type number (see Figure 4) that
matches the E&M connection for that channel. Perform the
following procedure if you need to move the E&M jumper block
from its default (Type 2) position.
1. Ensure that the external power supply is disconnected
from the MultiVOIP 200.
2. Turn the MultiVOIP 200 upside down and remove the
cabinet mounting screw at the center back of the cabinet.
3. Return the MultiVOIP 200 to its upright position, then slide
the base out the rear of the cabinet.
Note: To change a jumper position, lift the jumper plug up
off the jumper block, then move it to the new position,
ensuring that the middle jumper of the jumper block is
centered on the E&M type number (1,3,4,or 5) as shown
on Figure 4. (Note: Numbers are not on the board.)

Configuring Your MultiVOIP 200
The following steps provide instructions for configuring your
MultiVOIP 200. The configuration sequence includes IP
Protocol default setup, Channel setup, and Phone Directory
Database setup. The Phone Directory Database setup is
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 is displayed.
The default Frame Type is TYPE_II. If this does not match
your IP network, change the Frame Type by clicking the
drop-down arrow and selecting SNAP. 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 in
the corresponding fields.
The IP address is the unique LAN IP address that is
assigned to the MultiVOIP 200, and the Gateway address
is the IP address of the device connecting your MultiVOIP
200 to the Internet.
Click OK when you are finished.
13. The Channel Setup dialog box is displayed. The four tabs
in this dialog box define the channel interface, voice/fax
parameters, billing/miscellaneous parameters, and
regional telephone parameters for each channel.
18
Configuring the MultiVOIP
Configure each channel for the type of interface you are
connecting to. The Interface tab defaults to Channel 1 in
the Select Channel field. To change the channel number,
click the drop-down arrow and the list of channels is
displayed. Highlight the channel you want to configure.
Note: Feature options are enabled or disabled (grayed out)
according to the interface type that you select. The one
option available for all interface types is the Inter Digit
Time option. This 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 this happens,
it will be necessary to hang up and dial again. The default
setting is 2 seconds.
14. The Interface group defaults to FXS (Loop Start). Select
the interface option that corresponds to the interface type
being connected to the Voice/Fax Channel 1 jack on the
back panel of the MultiVOIP 200.
19
MultiVOIP Quick Start Guide
FXS (Loop Start): If a station device; e.g., an analog
telephone, fax machine, or KTS (Key Telephone System) is
connected to the Voice/Fax connector on the back of the
unit, FXS (Loop Start) will likely be the correct Interface.
FXS (Ground Start): If the station device uses ground
start, then choose the FXS (Ground Start) option. Refer to
the device’s user documentation.
For both FXS Loop Start and FXS Ground Start , the Ring
Count FXS window allows 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.
FXO: If you are using an analog extension from your PBX,
then choose the FXO option. Check with your in-house
phone personnel to verify the connection type.
If FXO is selected, the Dialing Options Regeneration,
Flash Hook Timer, and Ring Count groups are enabled.
Check with your local in-house phone personnel to verify
whether your local PBX dial signaling is Pulse or tone
(DTMF). Then, set the Regeneration option accordingly.
The Flash Hook Timer allows you to enter the time, in
milliseconds, for the duration of the flash hook signals
output on the FXO interface. The default setting is 600
milliseconds. The Ring Count FXO window allows you to
set the number of rings received on the FXO interface
before the MultiVOIP 200 answers the incoming call. The
default setting is 2 rings.
Note: Zero (0) means that the MultiVOIP 200 never
answers.
20
Configuring the MultiVOIP
For FXO-to-FXO communications, you can enable a
specific type of FXO Disconnect; Current Loss, Tone
Detection, or Silence Detection. (Check with your inhouse phone personnel to verify the preferred type of
disconnect to use.) Enabling Tone Detection activates the
Disconnect Tone Sequence options. For Disconnect Tone
Sequence, you can select from drop-down lists either one
or two tones that will cause the line to be disconnected;
the person hanging up a call must then hit the key(s) that
will produce those tones. For Silence Detection, select
One Way or Two Way, then set the timer for the number of
seconds of silence before disconnect. Note that the default
value of 15 seconds may be shorter than desired for your
application.
E&M: If you are connecting to an analog E&M trunk on
your PBX, then choose the E&M interface option to enable
the E&M Options group. Check with your local in-house
phone personnel to determine if the signaling is Dial Tone
or Wink and if the connection is 2-wire or 4-wire. If Wink
signaling is used, then the Wink Timer is enabled with a
default of 250 milliseconds. The range of the Wink Timer is
from 100 to 350 milliseconds. Consult with your local inhouse phone personnel for this timer setting.
Note: After configuring a given channel (1 or 2), you can
copy that channel’s configuration by clicking the Copy
button and everything on the Interface tab will be copied
to the other channel.
15. Repeat the above step to configure the interface type for
voice/fax channel 2.
21
MultiVOIP Quick Start Guide
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.
17. 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 200; and, 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 dropdown lists in the DTMF Gain group. When DTMF Out of
Band is checked, the unit reproduces the DTMF tones
instead of passing them through.
22
Configuring the MultiVOIP
Note: Only change the DTMF gain under the direction of
Multi-Tech Technical Support supervision.
18. To change the voice coder, first select the channel by
clicking the Select Channel down arrow (highlighting the
channel number) then click Manual in the Coder group. To
select the appropriate coder, click the Selected Coder
down arrow and highlight your new voice coder entry.
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 Network Administrator to
determine how much bandwidth is available.
19. 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 200,
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 200
uses a Jitter Buffer. The Jitter Value field allows the
MultiVOIP 200 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 a given
voice/fax channel, you can disable faxes in the Fax group.
20. You can enable the voice/fax advanced features by clicking
(checking) the silence compression, echo cancellation, or
forward error correction options.
23
MultiVOIP Quick Start Guide
The Silence Compression option defines whether silence
compression is enabled (checked) for this voice channel. If
silence compression is enabled, the MultiVOIP 200 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 200 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.
Note: After configuring a given channel (1 or 2), you can
copy that channel’s configuration by clicking the Copy
button and everything on the Voice/Fax tab will be copied
to the other channel.
24
Configuring the MultiVOIP
21. 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 MultiVOIP 200 in the Phone Number field.
22. 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.
25
MultiVOIP Quick Start Guide
Consecutive Packets Lost defines the number of
consecutive packets that are lost after which the call is
automatically disconnected. The default setting is 30.
Call Duration defines the maximum length of time (in
seconds) that a call remains connected before the call is
automatically disconnected. The default setting is 180
seconds. A call limit of three minutes may be too short for
most configurations. Therefore, you may want to increase
this default value.
23. You can set billing options for inbound and/or outbound
calls by checking them in the Billing Options group and
then entering the charge in cents per number of seconds.
24. A minimum and maximum set of values can be set for
Dynamic Jitter Buffer. When receiving voice packets from
a remote MultiVOIP 200, it is possible to experience
varying delays between packets due to traffic conditions
on the network. This is called Jitter. To compensate for this
effect, the MultiVOIP 200 uses a Dynamic Jitter Buffer. The
Jitter Buffer allows the MultiVOIP 200 to wait for delayed
voice packets by automatically adjusting the length of the
Jitter Buffer between configurable minimum and maximum
values. An Optimization Factor adjustment controls how
quickly the length of the Jitter Buffer is increased when
jitter increases on the network. The length of the jitter
buffer directly effects the voice delay between MultiVOIP
200 gateways.
The Minimum Jitter Value default setting is 150
milliseconds, the Maximum Jitter Value default setting is
300 milliseconds, and the Optimization Factor default
setting is 7.
Note: After configuring a given channel (1 or 2), you can
copy that channel’s configuration to the other channel by

(Note: Each of these sections starts with a step “27.”)
28
Configuring the MultiVOIP
Registering with a Gatekeeper Phone Directory
This section describes how to register H.323 endpoints
with the Gatekeeper. The H.323 Gatekeeper function
resides at a PC acting as the central point for all calls
within its zone and providing call control services to
registered endpoints. The Gatekeeper performs two
important call control functions: address translation from
LAN aliases to IP addresses, and bandwidth management
where the network manager has specified a threshold for
the number of simultaneous conferences on the LAN.
In a GateKeeper environment, you will be enabling the
GateKeeper option, entering an IP address for the
GateKeeper, accepting the default port number, and if the
GateKeeper network is servicing Fast Start, accept the
defaults in the Q.931 Parameters group. However, if this
network zone is primarily non-fast start supported, you will
disable Use Fast Start.
27. Enable the Gatekeeper option
29
MultiVOIP Quick Start Guide
28. If the GateKeeper network employs Fast Start, then accept
the Use Fast Start option (default). You may have to verify
this with the GateKeeper administrator.
29. Enter the Gatekeeper IP Address in the IP Address field
of the RAS Parameters group.
30. Accept the default Port Number 1719.
CAUTION: The default setting for the Gatekeeper Port
Number is 1719. This can be changed to a different value
by the Gatekeeper administrator. If you decide to change
the default Port Number, you must use the same number
on the Gatekeeper and all other H.323 endpoints.
31. When you are finished with this dialog box, click the Add
(+) button to begin building your phone directory database.
The Add/Edit Phone Entry dialog box is displayed.

MultiVOIP Quick Start Guide
Building a Proprietary Phonebook Directory
27. To build your proprietary MultiVOIP 200 Phone Directory
(i.e., in an H.323 environment without the Gatekeeper
option enabled), you will first need to enable (check) the
Proprietary Phonebook option and then configure the
“Host” MultiVOIP 200 and then add the “Client” MultiVOIP
200s (or other H.323 endpoints). Configuring the “Client”
MultiVOIP 200 is discussed later.
The first MultiVOIP 200 to be configured is designated the
“Host” and contains the proprietary phonebook database.
All subsequent MultiVOIP 200s added to the proprietary
phonebook database are designated “Clients.” The Host
database contains the phone numbers of all H.323
endpoints available for communication on an IP network.
This database is downloaded to each Client MultiVOIP 200
as it comes on-line.
28. To configure the “Host” MultiVOIP 200, make certain that
the Proprietary Phonebook and Host options are
enabled. The Host IP Address, Send Status Report to
Host, and RAS Parameters group will be disabled (grayed
out).
36
Configuring the MultiVOIP
The Client Status button displays the Client VOIP Status
dialog box used for viewing phone number, IP address,

Parameters group, Use Fast Start is checked for
compatibility with other H.323 devices that support Fast
Start Capability.
Click Add (+) to begin building your phone directory
database. The Add/Edit Phone Entry dialog box is
displayed.
29. Enter the unique phone number of the local device in the
Phone Number field (e.g., 101) and indicate that the local
device is connected to Channel 1 in the Voice Channel
field.
30. The Description field is optional, but can be useful in
associating the channel to the extension. If you wish, enter
a description of your local phone number. This description
serves to identify the phone number you entered in the
previous step (e.g., normally the “Host” MultiVOIP 200
resides at the entity’s main office; therefore, for this
example you could enter a description such as “New York
Office 1”).
37
MultiVOIP Quick Start Guide
31. The Station Identification group includes a Hunt Group
drop-down list. This list enables you to indicate which Hunt
Group you want the phone number to be associated with;
or, you can select NO HUNT if you don’t want this entry to
participate in hunting.
Note: Hunting is a series of telephone lines organized in
such a way that if the first line is busy the next line is
hunted and so on until a free line is found. For this
example, assign the phone entry to HUNT GROUP #1.
Once you have assigned this entry to a Hunt Group (or NO
HUNT), you must enter the IP Address of the Host
MultiVOIP 200 in the IP Address field (e.g.,
204.022.122.118).
Note: The Port field becomes active as you begin to enter
the IP Address. The entry is the H.323 industry standard
Port value (1720) used to communicate with other H.323
endpoints.
32. Click OK to return to the Phone Directory Database

MultiVOIP Quick Start Guide
Configuring Your Client MultiVOIP 200s
If the Proprietary Phonebook option on the Phone Directory
Database dialog box was enabled, then you will need to
configure all remote H.323 endpoints as “Client” units. For
example, the MultiVOIP 200 at the company’s subsidiary office
in London would need to be configured as a “Client.”.
CAUTION: If you are installing a MultiVOIP 200 behind a
Firewall, the Firewall must support H.323. Refer to your
Firewall user documentation to enable H.323 support.
1. Disconnect the PC from the Command port of the Host
MultiVOIP 200 and connect it to the Command port on the
Client MultiVOIP 200.
2. From your desktop, click Programs I MultiVOIP 200 I

Configuring MultiVOIP Slaves
Click (check) the Enable Diffserv box if you have routers
that support Diffserv (sometimes called IP Precedence).
This feature gives priority to voice packets so they are not
delayed because of large data files being downloaded.
The default Frame Type is TYPE_II. If this does not match
your IP network, change the Frame Type by clicking on the
drop-down arrow. The Frame Type choices are TYPE_II
and SNAP.
4. In the Port Address group, enter the IP Address and IP
Mask. In the Gateway Address group, enter the gateway
IP address for the Client unit.
The IP Address is the unique IP address that you assign to
the MultiVOIP 200, and the Gateway Address is the IP
address of the device (e.g., network router) connected to
the Internet/Intranet.
Click OK when you are finished. The Main menu is
displayed.
5. From the Main menu, click Voice Channels to display the
49
MultiVOIP Quick Start Guide
Channel Setup dialog box. The Channel Setup dialog
box is displayed. The four tabs in this dialog box define the
channel interface, voice/fax parameters, Billing/Misc
parameters, and regional telephone parameters for each
channel.
Configure each channel for the type of interface you are
connecting to. The Interface tab defaults to Channel 1 in
the Select Channel field. To change the channel number,
click the drop-down arrow and the list of channels is
displayed. Highlight the channel you want to configure.
Feature options are enabled or disabled (grayed out)
according to the interface type that you select. The one
option available for all interface types is the Inter Digit
Time option. This 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 this happens,
it will be necessary to hang up and dial again. The default
is 2 seconds.
50
Configuring MultiVOIP Slaves
6. The Interface group defaults to FXS (Loop Start). Select
the interface option that corresponds to the interface type
being connected to the Voice/Fax Channel 1 jack on the
back panel of the MultiVOIP 200.
FXS (Loop Start): If a station device; e.g., an analog
telephone, fax machine, or KTS (Key Telephone System) is
connected to the Voice/Fax connector on the back of the
unit, FXS (Loop Start) will likely be the correct Interface
option.
FXS (Ground Start): If the station device uses ground
start, then choose the FXS (Ground Start) option. Refer to
the device’s user documentation.
For both FXS Loop Start and FXS Ground Start , the Ring
Count FXS window allows 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 counts.
Note: Zero (0) means no rings - caller hears a busy tone.
FXO: If you are using an analog extension from your PBX,
then choose the FXO option. Check with your in-house
phone personnel to verify the connection type.
If FXO is selected, the Dialing Options Regeneration,
Flash Hook Timer, and Ring Count groups are enabled.
Check with your local in-house phone personnel to verify
whether your local PBX dial signaling is Pulse or tone
(DTMF). Then, set the Regeneration option accordingly.
The Flash Hook Timer allows you to enter the time, in
milliseconds, for the duration of the flash hook signals
output on the FXO interface. The default setting is 600
milliseconds. The Ring Count FXO window allows you to
51
MultiVOIP Quick Start Guide
set the number of rings received on the FXO interface
before the MultiVOIP 200 answers the incoming call. The
default setting is 2 counts.
Note: Zero (0) means that the MultiVOIP 200 never
answers.
For FXO-to-FXO communications, you can enable a
specific type of FXO Disconnect; Current Loss, Tone
Detection, or Silence Detection. (Check with your inhouse phone personnel to verify the preferred type of
disconnect to use.) Enabling Tone Detection activates the
Disconnect Tone Sequence options. For Disconnect Tone
Sequence, you can select from drop-down lists either one
or two tones that will cause the line to be disconnected;
the person hanging up a call must then hit the key(s) that
will produce those tones. For Silence Detection, select
One Way or Two Way, then set the timer for the number of
seconds of silence before disconnect. Note that the default
value of 15 seconds may be shorter than desired for your
application.
E&M: If you are connecting to an analog E&M trunk on
your PBX, then choose the E&M interface option to enable
the E&M Options group. Check with your local in-house
phone personnel to determine if the signaling is Dial Tone
or Wink and if the connection is 2-wire or 4-wire. If Wink
signaling is used, then the Wink Timer is enabled with a
default of 250 milliseconds. The range of the Wink Timer is
from 100 to 350 milliseconds. Consult with your local inhouse phone personnel for this timer setting.
Note: After configuring a given channel (1 or 2), you can
copy that channel’s configuration by clicking the Copy
button and everything on the Interface tab will be copied
to the other channel.
52

7. Repeat the above step to configure the interface type for
voice/fax channel 2.
8. 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.
9. 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 200; and, 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 drop53
MultiVOIP Quick Start Guide
down lists in the DTMF Gain group.
Note: Only change the DTMF gain under the direction of
Multi-Tech Technical Support supervision.
10. To change the voice coder, first select the channel by
clicking the Select Channel down arrow (highlighting the
channel number) then click Manual in the Coder group. To
select the appropriate coder, click the Selected Coder
down arrow and highlight your new voice coder entry.
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 VOIP administrator to
determine how much bandwidth is available.
11. 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 200,
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 200
uses a Jitter Buffer. The Jitter Value field allows the
MultiVOIP 200 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 a given
voice/fax channel, you can disable faxes in the Fax group.
54
Configuring MultiVOIP Slaves
12. 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 200 will not
transmit voice packets when silence is detected, thereby
reducing the amount of network bandwidth that is being
used by the voice channel.
This Echo Cancellation option defines whether echo
cancellation is enabled (checked) for this voice channel. If
echo cancellation is enabled, the MultiVOIP 200 will
remove echo-delay 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.
Note: After configuring a given channel (1 or 2), you can
copy that channel’s configuration by clicking the Copy
button and everything on the Voice/Fax tab will be copied
to the other channel.
55
MultiVOIP Quick Start Guide
The Billing/Misc tab displays the parameters for auto call,
automatic disconnection, billing options and dynamic jitter
buffer.
13. 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 200 in the Phone Number field.
14. 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.
56
Configuring MultiVOIP Slaves
Consecutive Packets Lost defines the number of
consecutive packets that are lost after which the call is
automatically disconnected. The default setting is 30
packets.
Call Duration defines the maximum length of time (in
seconds) that a call remains connected before the call is
automatically disconnected. The default setting is 180
seconds. A call limit of three minutes may be too short for
most configurations. Therefore, you may want to increase
this default value.
15. You can set billing options for inbound and/or outbound
calls by checking them in the Billing Options group and
then entering the charge in cents per number of seconds.
16. A minimum and maximum set of values can be set for
Dynamic Jitter Buffer. When receiving voice packets from
a remote MultiVOIP 200, it is possible to experience
varying delays between packets due to traffic conditions
on the network. This is called Jitter. To compensate for this
effect, the MultiVOIP 200 uses a Dynamic Jitter Buffer. The
Jitter Buffer allows the MultiVOIP 200 to wait for delayed
voice packets by automatically adjusting the length of the
Jitter Buffer between configurable minimum and maximum
values. An Optimization Factor adjustment controls how
quickly the length of the Jitter Buffer is increased when
jitter increases on the network. The length of the jitter
buffer directly effects the voice delay between MultiVOIP
200 gateways.
The Minimum Jitter Value default setting is 150
milliseconds, the Maximum Jitter Value default setting is
300 milliseconds, and the Optimization Factor default
setting is 7.

Deploying the VOIP Network
Deploying the VOIP Network
For a Proprietary Phone Directory database, the VOIP
administrator can deploy the pre-configured Client MultiVOIP
200s to their remote sites. The remote site administrators need
only connect power to the pre-configured MultiVOIP 200,
connect the MultiVOIP 200 to their Ethernet LAN and
predefined telephone equipment, and then wait for the phone
directory database to be downloaded.
With the Gatekeeper option enabled on the Phone Directory
Database dialog box, all MultiVOIP 200s are configured as
“Host” and cannot be downloaded. In this case, each
MultiVOIP 200 Phone Book will be programmed with phone
numbers for its own channels. These phone numbers are
registered with the H.323 Gatekeeper (See the “Registering
with a Gatekeeper Phone Directory” section discussed earlier.)

3. Connect a network cable to the ETHERNET 10Base-T
(RJ-45) connector on the back of your MultiVOIP 200.
4. If you are connecting a station device (e.g., analog
telephone, fax machine, or Key Telephone System (KTS)
to your MultiVOIP 200, connect the smaller end of a
special adapter cable (supplied) to the Voice/Fax Channel
1 FXS connector on the back of the MultiVOIP 200 and the
other end to the station device.
If you are connecting a PBX extension to your MultiVOIP
200, connect the smaller end of a special adapter cable
(supplied) to the Voice/Fax Channel 1 FXO connector on
the back of the MultiVOIP 200 and the other end to the
PBX extension.
62
Deploying the VOIP Network
If you are connecting an E&M trunk from a telephone
switch to your MultiVOIP 200, connect one end of an RJ45 phone cord to the Voice/Fax Channel 1 E&M
connector on the back of the unit and the other end to the
trunk phone jack.
If you are connecting to an E&M trunk, you need to ensure
that the E&M trunk jumper is in the correct position for the
E&M type trunk. The default E&M jumper position is E&M
type 2. To change the E&M jumper position, perform the
E&M jumper block positioning procedure.
5. Repeat the above step to connect the remaining telephone
equipment to each Voice/Fax Channel on your MultiVOIP.
6. Turn on power to the MultiVOIP 200 by placing the ON/
OFF switch on the back panel to the ON position. Wait for
the BOOT LED on the MultiVOIP 200 to go OFF before
proceeding. This may take a couple of minutes.
7. At this time your VOIP network should be fully operational.
Dial one of the sites in your network.

MultiVOIP Quick Start Guide
If your H.323 endpoint is not a MultiVOIP 200 (e.g., a PC with
NetMeeting software), the Systems Administrator for your
VOIP network should do the following.
1. Make certain that the H.323 endpoint (e.g., PC with
NetMeeting, router with voice, etc.) have been properly
connected to the network. Refer to the appropriate end
user documentation.
2. Acquire the relevant IP Addresses and/or H323 IDs (H323
IDs are required if Gatekeeper is enabled) from the other
H.323 endpoints that will participate in H.323 calls.
3. Enter these IP Addresses and H323 IDs (H323 IDs are
required if Gatekeeper is enabled) in your phonebook
directory.
