MultiVOIP 400 User Guide
Introduction
Welcome to Multi-Tech's new standalone Voice/IP Gateways which allow analog voice and fax
communication over an IP network. Multi-Tech’s new voice/fax over IP 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 your MultiVOIP to your telephone equipment, and then to your existing Ethernet LAN.
Once configured, the MultiVOIP then allows voice and fax to travel down the same path as your
traditional data communications.
The MVP400 is designed with four voice/fax channels (which offer three voice/fax interfaces per
channel), a 10M bps 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 on-line help system.

MultiVOIP 400 User Guide
Typical Application
Before Voice Over IP (VOIP) (voice over the Internet), a corporate office had a data connection to the
Internet and a voice connection to the public switched telephone network (PSTN). With VOIP, the two
networks can be tied together. To accomplish this, a MultiVOIP is connected between the public
switched telephone network and the data network as shown in the typical VOIP application in Figure
1-2. A MultiVOIP 400 at the corporate office is tied into the public switched telephone network thru the
corporate PBX and to the data network. The corporate MultiVOIP is an MVP400 with four voice/fax
channels connected to the PBX enabling the sales, marketing and regional offices to simultaneously
call in or fax on any one of the corporate telephone numbers. The sales office is using a MultiVOIP
MVP200 that is connected to the sales office Key Telephone System (KTS) in which a sales
attendant answers incoming calls and directs them to their proper destination. The marketing office
and regional offices also use MVP200s. The marketing office is set up with the MultiVOIP connected
to the E&M trunks on the PBX. The regional office uses an FXS interface to connect two analog
telephones directly to the local telephone network.
In this configuration, the corporate MultiVOIP is connected to analog trunks on the corporate PBX
and the Ethernet connection is plugged into the hub on the data network. The data network is
connected via a router to the Internet. In our typical application, any user at the corporate office can
pick up a telephone and call the sales, marketing, or regional office. To accomplish this, the caller
picks up the phone and dials a trunk extension, for example extension 4. This is the same principle
as dialing 9 for an outside line in a corporate environment. A second dial tone is heard, the caller then
dials extension 201 at the sales office. This rings the KTS at the sales office. The sales receptionist
answers the call and then directs the call (for example, you wanted to talk to the person at extension
5125) and a voice conservation takes place.

Figure 1-2. Example of a MultiVOIP application
The sales office is set up with a two voice/fax channel MultiVOIP MVP200 connected to the LAN with
one voice/fax channel connected directly to the local Public Switch Telephone Network (PSTN) and
the second voice/fax channel connected to the trunk side of the KTS. This enables an attendant to
direct incoming calls to any one of the telephones or fax machines connected to the Key Telephone
System at the sales office. This enables the corporate caller to call either the sales office or instead of

9
Chapter 1 - Introduction and Description
dialing extension 201, dials extension 202 and is now connected to the local telephone network at the
sales office. The corporate caller could then dial any telephone number from the sales office PSTN
and this would be a local call.
The regional office is set up very similar to the corporate office with the exception that a MVP200 is
connected between the network and the PBX. This enables two voice/fax channels to be used at the
regional office. A person in the regional office can pick up a telephone and dial a trunk extension (for
example, trunk extension 10) on the local PBX. This is the same as dialing a 9 for an outside line. A
second dial tone is heard, the caller would then dial the corporate MultiVOIP at one of the following
extensions (101 thru 104). When the third dial tone is heard, the caller could then dial any telephone
at the corporate office by dialing its extension, for example, extension 4123.
To configure a MultiVOIP, the COM port of a PC is connected to the Command port on the MultiVOIP.
Configuration software is loaded onto your PC and your unique LAN parameters must be established.
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 in a single dialog box as shown below. You can configure your
network IP address and mask for the MultiVOIP 400 and the gateway address for the corporate
router on the same dialog box.
For your corporate MultiVOIP, the Ethernet Frame Type is Type II, the IP Address is 201.22.122.118,
the Subnet Mask Address is 255.255.255.128, and the router Gateway Address is 201.22.122.1.
Once the LAN parameters are established, you can set up the voice channel parameters.
The channel setup parameters define the voice side of the MultiVOIP, the voice channel interface.
FXS (Ground and Loop Start) are for connecting to a standard analog telephone set, FXO (Foreign
Exchange Office) interface connects to the station side of a PBX, and E&M (Ear and Mouth)
connects to the trunk side of the PBX. Along with each interface there are additional parameters that
need to be considered, such as for FXO, the dialing options for DTMF (Touch-Tone) or Pulse, the
method of disconnecting (Current Loss or Tone Detection), and for E&M, signaling, mode, and the
wink timer settings in milliseconds.
In our typical application, you would configure the corporate office channel parameters for an E&M
interface. With this interface, you would have to consult with your in-house telephone people to

10
MultiVOIP 400 User Guide
determine how your PBX is configured. They would have to determine E&M signaling options (dial
tone or wink), 2-wire or 4-wire connection, and if the wink option is the signaling option, the wink timer
delay in milliseconds. The default is 250 milliseconds.
Additional channel setup parameters cover the voice coder, DTMF gain, voice gain, and faxing in the
Voice/Fax tab of the Channel Setup dialog box. The most important parameter in this group is to
ensure that the voice coder is the same for all MultiVOIPs in the network. The Billing/Misc tab
handles the billing options, automatic disconnect options, and the dynamic jitter buffer options. The
jitter options in this tab handle voice break up which can be particularly disruptive to voice
communications. For the most part, these parameters can remain in their default values. The
Regional tab defines the country or region in which the MultiVOIP is being used.
Once you have completed channel setup, you will need to add the phone numbers to the phone
directory database. The phone directory database establishes a host-client relationship between the
MultiVOIPs in your network. This relationship allows one MultiVOIP to maintain the Phone Directory
Database and send it to all MultiVOIP participants in the network.
Now, to add a phone number to the phone directory database, you bring up the Add/Edit Phone Entry
dialog box. The Station Information group in the dialog box defines the Phone Number, a Description
is optional, but may be helpful if it is assigned to an individual or department, in this case the
Corporate Office MultiVOIP, and Voice Channel of the unit, which is Channel 1 is this case. The
Permit Hunting option allows a phone number that is busy, to roll over to another extension.

11
Chapter 1 - Introduction and Description
The MultiVOIP Identification defines the MultiVOIP for which you are assigning the phone number.
The Type group (Dynamic or Static) defines the type of IP address that is used for this MultiVOIP.
The host MultiVOIP requires a static IP address so that the slave units know where the host
MultiVOIP is in the network. The Identified By group defines the IP address of the MultiVOIP for
which the telephone number is being assigned. The Ethernet Node ID number is the 12-digit Node
ID# (0008005xxxxx) that is assigned to every unit during the manufacturing process and cannot be
changed. It is located on the ID plate on the bottom of the unit.
When you have enterred this information in the Add/Edit Phone Entry dialog box, the new phone
number is added to the Phone Directory Database.
You would continue this process for the next 3 Voice Channels of the Corporate Office MultiVOIP
while changing the phone number and corresponding channel number. When you have enterred all
the Corporate Office numbers, then you would add the phone numbers for the Sales Office.
The Station Information is enterred with the same reasoning as for the host MultiVOIP. But, the
MultiVOIP Identification for the Sales Office client unit depends on how it is used in its network. For
example, if the client unit is behind a proxy server and the proxy server is providing the connection to
the Internet and the proxy server is using dynamic addressing (i.e., the ISP is assigning the IP
addressing), then this client MultiVOIP will use dynamic addressing and the IP Address field in the
Identified By group will be greyed out (inactive). If the proxy server is using static addressing, then
the Type group would be static and the IP Address field in the Identified By group would contain the
IP address of the proxy server. If the client MultiVOIP is connected to the Internet via a router, as in

12
MultiVOIP 400 User Guide
our Sales, Marketing, and Regional Offices in our Typical Application, then the router static IP
address is enterred in the IP Address field. When the Sales, Marketing, and Regional Offices in our
Typical Application are enterred into the Phone Directory Database of the Corporate MultiVOIP, the
phone directory database is complete. Now, whenever a MultiVOIP is turned on at any of the client
offices, the phone directory database is downloaded to the unit.
The phone directory database is now built so that whenever an office turns on its MultiVOIP the
database is downloaded to the client unit.
When a person in the Sales Office picks up the phone to call some one at the Corporate office, he/she
would dial extension 202 to direct the call through the Sales Office MultiVOIP. When a second dial tone is
heard, they would then dial one of the four extensions at the Corporate Office MultiVOIP (extensions 101
thru 104). Now, the call is sitting on the Corporate telephone switch (PBX). The person now could dial any
one at the corporate office by dialing their extension or if they wanted to dial some one in the local area via
the corporate public telephone network, they could dial a 9 for an outside line and then dial the telephone
number as if they were sitting at the corporate site.
Similarly, if a person in the Corporate Office wanted to dial the Regional Office, they would pick the
phone and dial one of the four Corporate Office MultiVOIP extensions (4 thru 7). This would direct the
call to the Corporate MultiVOIP and when the second dial tone is heard, they would dial 401 at the
Regional Office. This would ring the telephone at extension 401 in the Regional Office and the phone
conversation would take place.

MultiVOIP 400 User Guide
Installing 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, subnetwork 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 with the Host unit.
Configure your Client MultiVOIPs
Next, the administrator configures the MultiVOIPs designated as “Client” units. The Client units can
be another MVP 400, a MVP 800 unit, MVP200 or a MultiVOIP 100 series. Again, unique LAN IP
addresses, subnetwork 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 Client, and the IP address of the Host MultiVOIP is entered.
Once all client units are configured, the network is ready for deployment.
Deploy the VOIP Network
The final phase of installation is deployment of the network. Through the first two phases, the VOIP
administrator controls configuration. 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 powered up.
The final task of the VOIP Administrator is to develop the VOIP Dialing Directory based on the Phone
Directory Database and telephone numbers of the interfacing telephone equipment. At this point, a
VOIP User can call any person on the VOIP network.
Safety Warning Telecom
1. Never install telephone wiring during a lighting storm.
2. Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
3. This product is to be used with UL and cUL listed computers.
4. Never touch uninsulated telephone wires or terminals unless the telephone line has been

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 Sytems for battery replacement.
The E&M, FXS, and Ethernet ports are not designed to be connected to a Public Telecommunication
Network.

your unit. Plug the DB-25 end of the cable into the Command port of the MultiVOIP and the other
end into the PC serial port. See Figure 2-2.
4. Connect a network cable to the ETHERNET 10BASE-T connector on the back of the MultiVOIP.
Connect the other end of the cable to your network.
5. If you are connecting a station device such as an analog telephone, a fax machine, or a Key
Telephone System (KTS) to your MultiVOIP, connect one end of an RJ11 phone cord to the
Voice/Fax Channel 1 FXS connector on the back of the MultiVOIP and the other end to the
station device.
If you are connecting the station side of a telephone switch (PBX) to your MultiVOIP, connect one
end of an RJ11 phone cord to the Voice/Fax Channel 1 FXO connector on the back of the
MultiVOIP and the other end to the phone jack.
If you are connecting an E&M trunk from a telephone switch to your MultiVOIP, connect one end
of an RJ45 phone cord to the Voice/Fax Channel 1 E&M connector on the back of the MultiVOIP
and the other end to the trunk. Refer to Appendix B for E&M cabling pinout.
If you are connecting to an E&M trunk, you need 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.
6. Repeat the above step to connect the remaining telephone equipment to each Voice/Fax
Channel on your MultiVOIP.
7. Turn on power to the MultiVOIP by placing the ON/OFF switch on the back panel to the ON
position. Wait for the BTG LED on the MultiVOIP to go off before proceeding. This may take a
few minutes.
