VERY IMPORTANT NOTE:
The V300 is equipped with an automatic LifeLine feature which
will connect you to the emergency operator when 000 is dialled
on the handset. For this feature to function correctly, you need
a functioning telephone line and that line needs to be correctly
connected to the V300’s line port. NetComm will not be liable
to any person for any expenses, losses, damages or costs if the
emergency operator cannot be reached for any reason beyond
NetComm’s control, including but not limited to the non-existent
or incorrect connection of the telephone line to the V300; faults in
line cords, plugs or other cabling/exchange faults; lightning strikes
disabling the V300’s line circuits; the user disabling the LifeLine
support in the V300’s advanced features; problems with the user’s
handset or damage caused to the V300 by it; the user not having
a valid account with the telephone service providers for a regular
telephone service; and the ‘000’ service being congested or not
operational.

Chapter 1 Introduction
This chapter gives a brief introduction to the V300 VoIP Telephone Adaptor/Router, including a
product overview, description of the product features and its application.
1.1 Product Overview
The V300 has been designed for residential and small business users to deliver predictable
real-time voice quality over the Internet. It connects directly to any broadband modem and
service (Cable or DSL) which supports VoIP.
A standard analogue telephone (desktop or cordless) is connected to the Phone (FXS) port
on the back of the V300, allowing the user to route calls over the Internet to anywhere in the
world using VoIP, significantly reducing or eliminating long distance call charges.
The V300 is also equipped with a standard POST RJ-11 port which allows for the
connection of a regular telephone line. With this feature you can make or receive regular
phone calls with the same analogue telephone you use to make VoIP calls. This feature
also acts as a LifeLine or backup should your VoIP or Broadband service experience any
difficulties.
To enhance your VoIP experience and simplify network integration, the V300 is equipped
with a 3-port Switch and Quality of Service (QoS) Router. The V300’s QoS feature ensures
you maintain high-quality VoIP calls during periods of heavy Internet use by dynamically
calculating and prioritising the required upstream bandwidth.
The V300 can be configured as a DHCP server for LAN and Network Address Translation
(NAT) can be used to translate private addresses to public address. In this way, computers in
the LAN do not require public IP addresses in order to access the Internet.

1.3 Application
Please refer to the following diagram for a typical application of the V300. The V300
provides you with normal VoIP and router/switch capabilities, so it can work as a router and
a VoIP ATA (analog telephone adapter) at the same time. Figure 1 illustrates a simplified
connection for the V300. In addition to providing basic VoIP calls, the V300 is also capable
of handling your landline telephone calls (PSTN Pass-through) and provide you with a
“LifeLine” service if your V300 experiences network problems. The following is a brief
explanation of LifeLine and PSTN Pass-through:
Figure 1
LifeLine
Unlike other VoIP devices, the V300 integrates IP phone and landline telephone functions
in one box. When your VoIP service is unavailable, the landline telephone service can be
in operation. You can switch from VoIP to landline telephone automatically using the Auto
Switch feature, or switch manually by pressing the “##” key.
PSTN Pass-through
PSTN pass-through can best be described as a call waiting function, i.e. the ability to receive
incoming calls whilst engaged in another phone call. When a PSTN call arrives, the V300
can answer the call whether it is on-hook, on a VoIP call or on a PSTN call. This allows you
to respond to the incoming PSTN call accordingly. The detailed description of the PSTN
pass-through handling can be found in the User Manual Chapter 5 Call Handling.

1.4 System Minimum Requirements
• A valid SIP VoIP account from a VoIP Service Provider
• A Broadband service
• A Broadband Modem/Router (bridge-mode capable*)
• An Analog telephone with RJ11 line cord (Desktop, Cordless or Dect.)

*Note: In some cases, you may need to configure your broadband router in
bridge-mode. The V300 will perform routing on your network.
**Note: A micro filter is required for ADSL Broadband services if you plan on
using your existing telephone service (landline) with the V300.

1.8 Power-up, Boot and Reset
Please only power up your V300 after all cables are connected. The POWER LED should
always be on after the V300 has powered up. Once the power is on, the V300 will boot up
automatically. Do not do anything until the boot up process has completed.
Boot or reboot
During the booting period, all of the LEDs, except for the POWER LED, will flash
irregularly. This is part of the normal process. All LEDs should be stabilized after the V300
has completely booted up (on, off or regular flashing). The whole booting procedure takes
about 1.5 minutes. Do not do anything to the V300 during the boot up, as this may cause
unexpected results or even damage the V300.
Reset
Reset reloads the V300 to its factory default settings. After the V300 has completely booted
up, use a small object - like a ballpoint pen to press the button and hold it down for over
three seconds. The V300 will reset and all its parameters will return to their factory default
settings. Then the V300 will reboot automatically. You can also reset the V300 in the Reset
menu of its Web configuration page.

2.2 Typical Network Connections for the V300
The Quick Start section will show you how to connect the V300 to your network. A typical
ADSL and cable broadband network are illustrated here.
ADSL Broadband
In general, a residential ADSL router runs PPPoE client and DHCP server for your PCs
to share Internet access. In this case, you can just simply connect the V300 to your ADSL
router as shown in Figure 2. Your PCs can connect to any LAN port in either the ADSL
router or the V300.
Figure 2
Note: V300 also has advanced routing and QoS features. To use these
features in conjunction with ADSL broadband service, please refer to
Section 4.1 WAN setup and 5.2 VoIP QoS for details.

2.3 Installation
2.3.1 Cable Connections
• The Phone port of the V300 is connected to a normal analog phone using a RJ11 cable.
• The Line port of the V300 is connected to a landline wall socket directly or through a
microfilter for an ADSL connection using a RJ11 cable.
• The WAN port of the V300 is connected to your ADSL/Cable modem using a RJ45 cable.
• A LAN port of the V300 is connected to your PC using a RJ45 cable.
2.3.2 Power on your V300 and PC
Make sure all cables are connected properly, and then power on the V300. It will take
approximately 1 to 2 minutes for the V300 to boot up.
After the V300 is completely booted up, switch on your PC which is directly connect to
V300 via its LAN port. This PC is only required for V300 configuration period.
2.3.3 Connecting to the V300
The purpose of this section is to provide instructions on how to assign an IP address to your
PC. When the PC completely boots up, it might already be able to talk to the V300. You can
check it using “Ping” utility. If the connectivity is OK, you can skip this section and jump to
Section 2.3.4. This section are only required if you are having trouble accessing your V300.
HINT: To test the network connectivity between the PC and the V300, you can
open a DOS prompt (Start ► Run ► cmd) and execute coming “ping
192.168.30.1”. Once you receive a reply from the V300 you know that
the PC and talk to the V300.
The Please ensure your PC is setup as DHCP client mode, in which the V300 will assign a
valid IP address to your PC and allow it can communicate with your V300. The following
section provides instructions on how to set this up with different Windows Operating
Systems.
