1 Welcome
Overview
Congratulations on your purchase of the Max 8 or Max 8
Plus!
The Max 8 is a Voice over Internet Protocol device that
allows you to make multiple ingoing/outgoing calls over
the Internet using a single Ethernet LAN connection. The
Max 8 works like a gateway to convert the analog signal
from your telephone to Voice over Internet Protocol
(VoIP). It then uses the Local Area Network (LAN)’s
broadband connection to send calls over the Internet via
Net2Phone’s service platform. Since Net2Phone calls
bypass most of the Public Switched Telephone Network
(PSTN), the result is significant savings on long-distance
communications services.

Product Features
The Max 8 is a rack-mountable device that connects
directly into the existing LAN through an RJ-45 port. It
supports up to eight analog telephones or T.38 faxes,
each connected to the unit through an individual FXS port
(analog telephone port), and is intended for use by mid to
large-sized groups.

Max 8 and 8 Plus User’s Guide – Chapter 1

The Max 8 Plus is a rack-mountable device that connects
directly into an existing LAN through an RJ-45 port. It
contains two removable interface cards, each containing
four RJ-11 ports. Interface cards may contain either four
FXS ports or four FXO ports. Max 8 Plus units are
configured to order, and may have FXS only, FXO only, or
both types of ports. Cards containing FXS ports are
labeled FSU, while those containing FXO ports are labeled
FOU.
 FXS (Foreign Exchange Station) interfaces are
used to connect standard analog devices such as
corded and cordless telephones or fax machines.
Optionally, they may be connected to the analog
trunk card on PBX, APBX, or KPS (Key Phone
System) systems. They are used to place
outgoing calls over the Internet and to receive
incoming calls from other Net2Phone devices.
 FXO (Foreign Exchange Office) ports connect to
the analog line card on a PBX, APBX, or KPS
(Key Phone System), or to an analog phone jack,
to provide connectivity to the Max from phones
both inside and outside of the PBX system. In
addition to the FXS functions, FXO ports provide
limited IVR (Interactive Voice Response)
functionality, which includes multiple options for
caller greetings, passwords, and Internet call
forwarding. This allows the Max 8 Plus to assume
many IVR functions when the PBX does not
provide them. If you would like to send a fax
through the FXO port, you must first connect the
fax machine to the PBX analog line interface
card.
A separate port with its own telephone line connection to
the PBX, or to an analog telephone, is required for every
concurrent telephone call (or conversation). For example,
if the capability for five concurrent calls is desired, then the
Max must have at least five ports connected to the PBX or
to analog telephones.
The Max 8 and Max 8 Plus features several proprietary
Quality of Service (QoS) enhancements, including
1. G.168 echo cancellation
2. Voice activity detection (VAD)

Max 8 and 8 Plus User’s Guide – Chapter 1
3
3. Comfort noise generation (CNG)
4. Dynamic jitter buffer control
More feature highlights include:
 Improved Call Quality – The Max 8 and 8 Plus
are compatible with more state-of-the-art
gateways such as Nuera and Cisco (when
available), which greatly improves the quality of
calls with reduced latency.
 Dropped Call Prevention – The Max 8 and 8
Plus are now more reliable in retaining calls in
progress by re-establishing connections to call
controllers if an IP stream is lost. This feature will
greatly improve dropped call problems for ADSL
or Cable modem users as well as LAN network
users.
 Account Balance Announcement by Port –
The Max 8 and 8 Plus have a Web configurable
toggle switch that enables the IVR to announce
the account balance or minutes remaining on the
port that the call is going over.
 Greeting Message - A greeting message will
play prior to the dialed call being sent to the call
servers.
 Call Detail Record (CDR) Generation –
Administrators can select to have CDRs
generated and sent to the Max Automated Billing
System (ABS).
 TX/RX Silence Detection – The Max 8 and 8
Plus detect both TX/RX silence on an FXO port
and then disconnects the call based on the
duration of call silence.
 Multiple Frames per Packet Support - The Max
8 and 8 Plus support multiple frames per packet
on the G.732.1 codec.
 Upgraded Vocfiles – Updated vocfile included
with software upgrade.
 T.38 Fax Protocol Supported – The Max 8 and
8 Plus feature enhanced fax functionality,
including built-in redundancy and higher success
rates.

Max 8 and 8 Plus User’s Guide – Chapter 1
4
 Multiple DID – The Max 8 and 8 Plus support the
DID service by using multiple port hunting for a
single DID account.
 Outbound Call Allow List –Each port has its
own class to make a call as the PBX’s CoS
(Class of Service). The CoS is classified into
several categories.
 Multiple Call Completion (MCC) – The Max 8
and 8 Plus support the Multiple Call Completion
feature. The user only needs to provide the
account number and PIN once, after which the
user can place multiple calls from the FXO port
by pressing the “#”key after the first call is
completed.
 Multiple Password Support – The Max 8 and 8
Plus supply multiple passwords for port access.
 Local Dialing System – This version features
the addition of the Local Dialing System, which
enables users to dial phone numbers on the Max
8 and 8 Plus as they normally do on their
ordinary phones. That is, users do not have to
dial an international call access number and
country code number if the call destination is the
same country where user lives. Similarly, the
area code can be omitted for calls made to the
same area. Users can configure a dialing pattern
on the Max 8 and 8 Plus that is as close as
possible to the host country's dialing pattern.
 FTP Block – The new FTP Block feature enables
the Max 8 and 8 Plus to block an FTP
connection. If a user wants to connect the Max 8
and 8 Plus through FTP for an upgrade, the user
has to start the FTP server daemon in the Max
unit. This is a good function to block unwanted
outside connections.
 HTTP Port Change – The Max 8 and 8 Plus
include a feature that allows the HTTP port
number to be changed from the standard port 80
using HyperTerminal and Telnet. Changing the
port number to a number other than 80 increases
the security for users accessing the Web
Manager.

Max 8 and 8 Plus User’s Guide – Chapter 1

New Features and Functionality
Version 1.5.40 provides the following new features:
 Polarity Reversal – The new version of Max 8
now supports polarity reversal, which allows the
Max 8 to connect to a billing machine that uses
reverse polarity to determine the start and end of
a call.
IMPORTANT: Before upgrading to version
1.5.40, please refer to the Download Latest
Firmware section on page 63 in this Guide.
If you have an older version of the Max 8 or 8 Plus
