							6 Chapter 1 - Introduction and Description
Introduction
Welcome to Multi-Techs new voice/fax gateway, the MultiVOIP, model MVP110. The MVP110 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 MVP110 to a phone or to your existing in-house phone switch and then to your existing
Internet connection. Once configured, the MVP110 allows voice and fax to travel down the same path
as your traditional data communications.
The MVP110 supports the H.323 standards-based protocol enabling your MVP110 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 MVP110 is designed with one 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.

							8 Chapter 1 - Introduction and Description
Typical Application
Before Voice Over IP (VOIP), 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 MVP110 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 at the corporate office is connected between the data
network and the corporate telephone switch (PBX). To connect the MultiVOIP 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 is connected to two FXO jacks on the back
of the MultiVOIP 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 MVP110 at the remote branch office, the Ethernet jack on the MVP110 is connected to
the hub and the two analog phones are connected by a phone cord to the FXS jack on the MVP110.
To configure a MVP110, the COM port of a PC is connected to the Command port on the MVP110.
Configuration software is loaded onto your PC and your unique LAN parameters must be entered.
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 MVP110 and the gateway address for the corporate router on
the same dialog box.     
						

							9 Chapter 1 - Introduction and Description
For your corporate MultiVOIP, the Ethernet Frame Type is Type II, the IP Address is 169.254.26.12,
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
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.  The voice channel interface,
FXS is for connecting to a standard analog telephone set.
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 used.
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.
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     
						

							10 Chapter 1 - Introduction and Description
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 master-slave
relationship where the master MultiVOIP maintains the phone directory and downloads the directory
to each slave 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 (such as
Microsoft Netmeeting).  (2) If you choose the Proprietary PhoneBook, 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.
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 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 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.
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.  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.
