Chapter 1 - Introduction to the MultiVOIP
The MultiVOIP 100 (Model MVP120) allows analog voice and fax communication over a
traditional IP network. Multi-Tech’s new voice/fax gateway technology allows voice and fax
communication to be transmitted, with no additional expense, over your existing
communications Internet, which has traditionally been data-only . To access this free voice
and fax communication, all you have to do is connect the MVP120 to an FXO PBX port or
PSTN and then to your existing Internet connection. Once configured, the MVP120 allows
voice and fax to travel down the same path as your traditional data communications.
The MVP120 supports the H.323 standards-based protocol enabling your MVP120 to
participate in real-time conferencing with other third-party VOIP Gateways or endpoints that
support the H.323 protocol (such as Microsoft NetMeeting
how endpoints make and receive calls, how endpoints negotiate a common set of audio and
data capabilities, how information is formatted and sent over the network, and how endpoints
communicate with their respective Gatekeepers. Gatekeeper software is optional and if
present in a network, it typically resides on a designated PC. It acts as the central point for all
calls within its zone and provides call control services to all registered endpoints. In addition,
Gatekeepers can perform bandwidth management through support for Bandwidth Request,
Confirm, and Reject messages.
Note: A zone consists of all H.323 endpoints that are under the Gatekeeper’s control.

). The H.323 standard defines
The MVP120 is designed with one FXO 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 a comprehensive Help
system.

T ypical Application
Before VOIP (Voice Over IP) technology existed, a sales office used a data connection to the
Internet and a voice connection to the public telephone network. Now , with VOIP, the two
networks can be tied together. To accomplish this a Sales Office MultiVOIP is connected
between the public telephone network and the data network as shown in the typical
application below. The Sales Of fice MultiVOIP is going to be set up as the master MultiVOIP
and the MultiVOIP at the Remote Sales Office is going to be set up as the slave MultiVOIP.
With this approach, the person at the Remote Sales Office can pick up the telephone and dial
the Sales Office MultiVOIP and, after a second dial tone, can call anyone in the Sales Office,
or dial 9 for outside line and call anyone in the calling area as if they were at the Sales Office.

Typical VOIP Application
To set up this VOIP network, an MVP120 at the Sales Office is connected between the data
network and the sales office telephone switch (PBX). To connect the MVP120 to the data
network, an Ethernet cable is connected to the Ethernet port on the unit and the other end is
plugged into a hub on the data network. On the PBX side, one phone cord is connected to
the FXO jack on the back of the MVP120 and attached to an FXO port on the phone switch.
The line on the PBX occupies phone extension 4124.
To set up a remote sales office, connect the Ethernet jack on an MVP110 to the hub, and
connect (by a phone cord) a telephone to the FXS jack on the MVP1 10.
To configure the MVP120, the COM port of a PC is connected to the Command port on the
MVP120. The configuration software is based on a standard Windows Graphical User
Interface (GUI) which simplifies your selection process to a single parameter group within a
dialog box. For example, your LAN IP parameters are contained on a single dialog box. You
can configure your network IP address and mask for the MVP120 and the gateway address
for the corporate router on the same dialog box.
After your network configuration is complete, then you can develop your VOIP phone
directory database. This database will be developed on the Sales Office MultiVOIP and sent
out to the Remote Sales Office.
You will need to add the phone numbers to the phone directory database. Before you set up
the phone directory database, you need to consider how the database is going to be used:
Are you going to have an H.323 Gatekeeper setup your call sessions,
or
Are you going to control your call sessions using the proprietary phone book?
Multi-Tech Systems, Inc. MultiVOIP User Guide
8
Chapter 1 - Introduction to the MultiVOIP
The H.323 Gatekeeper acts as the central point for all calls within its zone and provides call
control services to registered endpoints. If you choose the proprietary phone book, you
establish a master-slave relationship where the master MultiVOIP maintains the phone
directory and downloads the directory to each slave unit.
The Gatekeeper/Proprietary Phone Book selection is chosen from the Phone Directory
Database dialog box. Before you choose how the data base is going to be used, here are a
couple of things to keep in mind:
1. If a Gatekeeper is employed in the network, you need to choose the Gatekeeper option.
You can not mix the Proprietary Phone Book with the Gatekeeper. If you choose the
Gatekeeper option you can communicate with other third party endpoints that support
H.323 (such as Microsoft Netmeeting).
2. If you choose the Proprietary Phone Book, you establish a master-slave relationship in
which the master MultiVOIP maintains the phone directory database. All of the phone
numbers are listed in the data base so that if you want to communicate with someone in
your VOIP network, you can see the phone number in your data base. Everytime you
bring up your MultiVOIP the current phone directory is downloaded to your MultiVOIP.
Note: You can still call Netmeeting using the proprietary phone book.
The Gatekeeper
The GateKeeper is a separate application that can operate on a network pc and provides all
the controls needed to create, control, and manage an H.323 network zone. The H.323
network zone is all the endpoints (terminals and gateways (MultiVOIPs)) that are registered
with the gatekeeper. The gatekeeper function is address translation from LAN aliases for
terminals and gateways to IP addresses as defined in the RAS (Registration/Admission/
Status) specification. The RAS Protocol defines the communication with a gatekeeper and
support for RTP/RTCP for sequencing audio packets. The H.323 Gatekeeper also provides
call-authorization for both accepting and placing calls in its zone, and certain monitoring
features such as call permissioning and address resolution.
If you choose the Gatekeeper option, initially you need to communicate with the administrator
of the Gatekeeper to register your MultiVOIP. The information you need from the Gatekeeper
administrator is the IP address of the Gatekeeper and its port number . Then you need to
establish your alias address which includes phone number, channel number, H323 ID which
can be a numeric or an alphanumeric value, and your MultiVOIP LAN IP address. The port
number is 1720, but if the Gatekeeper uses a different port number , you have to ensure that
Multi-Tech Systems, Inc. MultiVOIP User Guide

Chapter 1 - Introduction to the MultiVOIP
you use the same port number. The Gatekeeper administrator will then enter your information into
the Gatekeeper data base. This concludes the preregisteration.
You can enter your alias address information into the Add/Edit Phone Entry dialog box. For
example, if you were setting up the corporate MultiVOIP, you could enter the following information
for the V oice/Fax Channel : Channel 1 of the corporate MultiVOIP uses extension 101. The
Description is optional, but it may be helpful if it is assigned to an individual or department.
The H323 ID assigned to this phone number identifies the office using this extension. The IP
Address of the Corporate MultiVOIP is 201.022.122.118. The default port number 1720 is used.
Once the MultiVOIP goes online, the Gatekeeper registers it with the above H.323 ID. No other
H323 endpoint can use this H.323 ID. This is like your own telephone number .
After you have entered the information in the Add/Edit Phone Entry dialog box and clicked OK,
the new phone number is added to the Phone Directory Database.
Proprietary Phone Book
If you choose the Proprietary Phone Book option in the Phone Directory Database dialog box
instead of the Gatekeeper option, the Database Type group becomes active and the RAS
Parameters group becomes inactive.
When you elect to use the Proprietary Phone Book, you set up a master-slave relationship. This
relationship allows one MultiVOIP to maintain the Phone Directory Database and publish this data
base to all MultiVOIP participants in the network. This proprietary database allows you to see all
the participants in your network and provides you with their phone numbers.
To set up a database so that the corporate MultiVOIP can call the remote branch office and the
remote branch office can call the corporate MultiVOIP, the Phone Directory Database will have
one entry for the corporate office and one entry for the Remote Branch Office. Extension 101 at
the corporate office is tied to voice channel 1. The Description again is optional. The Hunt Group
in this example is set for No Hunt. However, if you want to activate a Hunt Group (if an extension
on the MultiVOIP is busy and you wanted to look for another extension), you can assign a hunt
group to those extensions. In other words, if extension 101 is busy , the corporate MultiVOIP
would roll over to extension 102, if you have multiple voice channels.
Multi-Tech Systems, Inc. MultiVOIP User Guide
10
Chapter 1 - Introduction to the MultiVOIP
Again, the corporate MultiVOIP IP Address needs to be added. The port number is 1720.
This adds phone number 101 of the corporate MultiVOIP to the proprietary database.
After you have added Channel 1, you need to include Channel 1 at the remote branch office.
The proprietary database would then appear as in the following dialog box and when the
remote branch office MultiVOIP is turned on, the current database would be downloaded to
the remote branch office MultiVOIP.
So, if a sales person in the Sales Office picked up the telephone and dialed extension 4124,
the extension routes the telephone call to the VOIP network. After the second dial tone, the
person would dial extension 201. The telephone at the Remote Sales office would ring and a
telephone conversation is initiated just as if the Remote Sales office had been called over the
regular telephone network.
Multi-Tech Systems, Inc. MultiVOIP User Guide
11
Similarly, if a person at the Remote Sales office picked up extension 201 and dialed
extension 101, the MultiVOIP at the Sales Office would generate a second dial tone and the
person at the Remote Sales office would then dial any extension at the Sales Office, or the
person could then dial a 9, for example, and get an outside line of the Sales Office Public
Switched Telephone network. This person could then dial any telephone number, as if calling
from the Sales Office.

Chapter 2 - Installation
Overview of the Installation Process
The basic steps of installing your MVP120 network involve unpacking the units, connecting
the cables, and configuring (Configuring is discussed in detail in Chapter 3) the units using
the included management software (MultiVOIP Configuration). The recommended installation
process includes four phases that, when completed, result in a fully functional Voice Over IP
network.
Unpacking and Cabling the MultiVOIP
The MultiVOIP package includes the MultiVOIP 100, a printed Quick Start Guide, a system
CD, a power supply, and a RJ-45 cable. If any one of these items is missing, please contact
you sales representative. Detailed cabling directions are included in this guide.
Installing the Software and Configuring Your MVP120
The VOIP administrator must first install the MVP120 software and then configure each
MVP120 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.
Chapter 2 - Installation
If your VOIP network supports Gatekeeper software, 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 configuration of the “Master” MultiVOIP has been completed, the administrator moves
on to configure the MVP120(s) designated as “Slave” 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 is set to Slave, and the IP address of the Master MultiVOIP
is entered. 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 to connect the units to
their LAN and telephone equipment. A full Phone Directory Database (supplied by the Master
MultiVOIP 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 will be registered with the Gatekeeper (the Gatekeeper
phonebook directory is not downloaded to the remote units). The final task of the VOIP
administrator or the Gatekeeper administrator is to develop the VOIP Dialing Directory based
on the appropriate phone directory database (the Proprietary phonebook database or the
Gatekeeper phonebook database).

The following steps provide instructions for configuring your MVP120. The configuration
sequence includes IP Protocol default setup, Channel setup, and Phone Directory Database
setup. The numbering of steps continues from the previous section.
12. The IP Protocol Default Setup dialog box displays.
The default Frame T ype is TYPE_II. If this does not match your IP network, select SNAP
from the Frame T ype list. The available Frame Type choices are TYPE_II and SNAP.
13. 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 MVP120, and the
Gateway address is the IP address of the device connecting your MVP120 to the
Internet.
Click OK when you are finished.
14. 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.
Check with your in-house telephone personnel to verify whether your local PBX dial
signaling is Pulse or DTMF (tone). Select the regeneration option accordingly .
In the Inter Digit Time box, enter the maximum amount of time between dialed digits in
milliseconds 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 numbers
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 the duration of flash hook signals
output on the interface. The default setting is 600 milliseconds.

15. The Ring Count FXO box enables you to set the number of rings received on the
FXO interface before hanging up and releasing the line to another call. The default
setting is 2 rings.
Note: Zero (0) means no incoming calls will be answered.
For FXO-to-FXO communications, you can enable a specific kind of FXO
Disconnect Options: 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 hang up when it detects a loss of current on the FXO
(phone) port. For tone detection, select from the lists 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 set the timer for the number of seconds of silence before
disconnect. The default value of 15 seconds may be shorter than desired for your
application.
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.
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 into the voice channel
before it is sent over the Internet to the remote MVP120. 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 lists in the V oice 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 lists
in the DTMF Gain group. When the DTMF Out of Band check box is selected, the
tones are passed via RTP packets, and the receiving VOIP reproduces the DTMF
tones instead of passing them through like voice.
Note: Only change the DTMF gain under the direction of Multi-Tech Technical
Support.
18. To change the voice coder, select the Manual option in the Coder group. Select the
appropriate coder from the Selected Coder list.
Multi-Tech Systems, Inc. MultiVOIP User Guide
25
Chapter 4 - Configuring the Master MultiVOIP
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 Automatic Coder is selected, then you need to select the Max Bandwidth from
the 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, the fax volume, and change the jitter value in
milliseconds.
When receiving fax packets from a remote MVP120, 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 MVP120 uses a Jitter Buffer. The Jitter Value box allows
the MVP120 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 selecting 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 MVP120 will not transmit
voice packets when silence is detected, thereby reducing the amount of network
bandwidth that is being used by the voice channel.
If Echo Cancellation is enabled, the MVP120 will remove echo which improves the
quality of sound.
The Forward Error Correction (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.
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 number), click the Auto Call Enable option in the
Auto Call group. Then enter the phone number of the remote channel in the Phone
Number box.
22. The Automatic Disconnection group provides three options to be used singly or in
combination.
Multi-Tech Systems, Inc. MultiVOIP User Guide

Chapter 4 - Configuring the Master MultiVOIP
The Jitter V alue 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 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.
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 MVP120, 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 MVP120 uses a Dynamic Jitter Buffer. The Jitter Buffer
allows the MVP120 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 MVP120 gateways.
The Minimum Jitter V alue default setting is 150 milliseconds, the Maximum Jitter Value
default setting is 300 milliseconds, and the Optimization Factor default setting is 7.
If your country/region is not the default USA, click the Regional tab and proceed to step
25; otherwise, click OK and proceed to step 26 to begin building your phone directory
database.
25. To change the T one Pairs on the Regional tab, select your country or region from the
Country/Region list. If your country or region is not listed, click Custom to define it.
The Tone Pairs group enables you to select and modify the parameters. Click OK when
finished. Proceed to Step 26 to begin building your phone directory database.

enables you to select either the GateKeeper or Proprietary PhoneBook. Once you have
choosen the type of Phone Book database, you can proceed to registering with a
Gatekeeper in the following section (entitled, Registering with a Gatekeeper Phone
Directory).
If you are building a proprietary phone book, proceed to page 31. On page 31 the
Building a Proprietary Phonebook Directory section starts with Step 27. It is a
continuation of Step 26 on this page.
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, disable Use Fast Start.
27. Enable the Gatekeeper option
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 box.
