							6 MultiVOIP 400/800 User Guide
Introduction
Welcome to Multi-Techs new voice/fax gateway, the MultiVOIP, models MVP400 and MVP800
(Hereafter referred together as MultiVOIP 400/800). The MultiVOIP 400/800 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
400/800 to a phone or to your existing in-house phone switch and then to your existing Internet
connection. Once configured, the MultiVOIP 400/800 allows voice and fax to travel down the same
path as your traditional data communications.
The MultiVOIP 400/800 supports the H.323 standards-based protocol enabling your MultiVOIP 400/
800 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 or gateway. 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.
The MVP400 is designed with four voice/fax channels (which offer three voice/fax interfaces per
channel), a 10 Mbps Ethernet LAN interface, and a command port for configuration.  The MVP800 is
designed with eight voice/fax channels, 10 Mbps Ethernet LAN interface, and command port.
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.

							8 MultiVOIP 400/800 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 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 400/800 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 MVP400/800 with
four voice/fax channels connected to the PBX allowing 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 MVP 200 that is connected to the sales office Key Telephone System (KTS) in
which a sales attendent answers in-coming 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 anlaog 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 allows an attendent to
direct incoming calls to any one of the telephones or fax machines connected to the Key Telephone
System at the sales office.  This allows the corporate caller to call either the sales office or instead of
dialing extension 201, dials extension 202 and is now connected to the local telephone network at the    
						

							9 Chapter 1 - Introduction and Description
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 allows 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 MultiVIOP 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 (See below).  You can configure your network
IP address and mask for the MultiVOIP 400/800 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, 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.
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
determine how your PBX is configured.  They would have to determine E&M signaling options (dial     
						

							10 MultiVOIP 400/800 User Guide
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 is 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.
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 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
