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
® ). 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 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.

Typical 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 Office 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 MVP110.
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? 
						

							9 Chapter 1 - Introduction to the MultiVOIP Multi-Tech Systems, Inc. MultiVOIP User Guide
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 
						

							10 Chapter 1 - Introduction to the MultiVOIP Multi-Tech Systems, Inc. MultiVOIP User Guide
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 Voice/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.
