MultiVOIP 200 User Guide
Introduction
Welcome to Multi-Tech's new voice/fax gateway, the MultiVOIP, model MVP200. The MultiVOIP 200
allows analog voice and fax communication over a traditional data communications/data networking
digital Internet. 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 MultiVOIP 200 to a phone or to your existing in-house phone switch and then to your
existing Internet connection. Once configured, the MultiVOIP 200 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
participate in real-time conferencing with other third-party VOIP Gateways or 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, 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 MVP200 is designed with two voice/fax channels (which offer three voice/fax interfaces on each
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.

MultiVOIP 200 User Guide
Typical Application
Before Voice Over IP (VOIP), i.e., 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 200 is connected between the
public switched telephone network and the data network at the corporate office as shown in the
typical VOIP application in Figure 1-2. The remote branch office has two standard telephones
connected to the MultiVOIP and its 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, a user at the
corporate office picks up a telephone connected to their local telephone switch (PBX) and calls the
remote branch office by dialing extension 4124 on the corporate MultiVOIP. When the second dial
tone is heard, the caller then dials extension 301 at the remote branch office. The remote branch
office telephone rings and a voice conservation takes place.

Figure 1-2.Typical VOIP Application
To set up this VOIP network, a MultiVOIP 200 at the corporate office is connected between the data
network and the corporate telephone switch (PBX). To connect the MultiVOIP 200 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 phone side, two phone cords are connected to two FXO jacks
on the back of the MultiVOIP 200 and attached to two station lines on the phone switch. These two
lines on the PBX occupy phone extensions 4124 and 4125.
To set up a MultiVOIP 200 at the remote branch office, the Ethernet jack on the MultiVOIP 200 is
connected to the hub and the two analog phones are connected by phone cords to the FXS jacks on
the MultiVOIP 200.
To configure a MultiVOIP 200, the COM port of a PC is connected to the Command port on the
MultiVOIP 200. 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 on a single dialog box (see below). You
can configure your network IP address and mask for the MultiVOIP 200 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. The
remote branch office would have the same Frame Type, a LAN IP address of 206.25.124.120 and a

9
Chapter 1 - Introduction and Description
Gateway Address of 206.25.124.110. 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, that is, 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 (Touchtone) or Pulse, the
method of disconnecting (Current Loss or Tone Detection), and for E&M, signaling, mode, and the
wink timer settings in 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 the MultiVOIP is being used in.
In our typical application, you would configure the corporate office channel parameters for an FXO
interface. With this interface, the defaults for the Dialing Options and the type of Disconnect could
remain as the defaults. For the remote branch office, the interface would be FXS with Loop Start
being used in most cases.

MultiVOIP 200 User Guide
Once you have completed channel setup, 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. 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 Host-Client
relationship where the Host MultiVOIP maintains the phone directory and downloads the directory to
each Client unit.
The decision on building the phone directory database is contained in 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 PhoneBook with the Gatekeeper. If you choose the
Gatekeeper option you can communicate with other third party endpoints that support H.323 (e.g.,
Microsoft Netmeeting). (2) If you choose the Proprietary PhoneBook, you establish a Host-Client
relationship in that the Host 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.
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 functions are 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 (i.e., call permissioning and address resolution).
So, 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 is a name, 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 you use the same port number. The Gatekeeper administrator will
then enter your information into the Gatekeeper data base. This concludes the preregisteration.
Now, 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

11
Chapter 1 - Introduction and Description
Voice Channel 1. For instance, in our typical application channel 1 of the corporate MultiVOIP uses
extension 101. The Description is optional, but can be helpful if you assigned to a particular
individual or department, or in this case it defines the channel interface.
The H323 ID that was assigned to this phone number which identifies the office that is using this
extension. The IP Address of the Corporate MultiVOIP is 201.022.122.118 and the default port
number 1720 is used.
So now when you “come alive”, the Gatekeeper will register you with the above alias address. No
other H323 endpoint can use this alias. This is like your own telephone number.
Now, if you choose the Proprietary PhoneBook option in the Phone Directory Database dialog box
instead of the Gatekeeper option, the Database Type group would become active and the RAS
Parameters group is inactive (greyed out).
Now, lets change the typical application to not have the Gatekeeper control the call session. When
you elect to use the Proprietary PhoneBook, you set up a Host-Client 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 data base allows you to see all the
participants in your network and provides you with there phone numbers.
Lets again start with the corporate MultiVOIP and we will set up the database so that the corporate
MultiVOIP can call the remote branch office and the remote branch office can call the corporate
MultiVOIP. To do this, the Phone Directory Database will have two entries for the corporate office and
two entries for the Remote Branch Office. Extension 101 at the corporate office is tied to voice
channel 1 and extension 102 to channel 2. The Description again ties to the type of interface used
on the corporate MultiVOIP (FXO). The Hunt Group in this situation is set for No Hunt. But if you
wanted to activate a Hunt Group, i.e., 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. So that, say extension
101 is busy, the corporate MultiVOIP would roll over to extension 102.

12
MultiVOIP 200 User Guide
Again, the IP Address of the corporate MultiVOIP needs to be added and the port number is 1720.
This adds phone number 101 of the corporate MultiVOIP to the proprietary data base. Now, to add
extension 102 to the proprietary data base, all you have to do is change the Phone Number and
Description to support channel 2 of the corporate MultiVOIP. After you have added channel 2, you
need to include the two channels at the remote branch office.
The proprietary data base would then appear as in the following dialog box and when the remote
branch office MultiVOIP is turned on, the current data base would be down loaded to the remote
branch office MultiVOIP.

MultiVOIP 200 User Guide
InstallingYour 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 general description is provided below
and detailed instructions are provided in Chapter 3, Software Loading and Configuration.
Installing and ConfiguringYour 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 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 “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 with the Host unit.
Once configuration of the “Host” MultiVOIP 200 has been completed, 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 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 to 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). The final task of the VOIP administrator or the Gatekeeper administrator is to
