1 Product Overview
1.1 Introduction to IP Telephony
Internet Protocol (IP) has its implementations in voice field. An example of this is the IP
phone system, which carries voice via IP packets and can be implemented in IP
networks, such as Intranets, WANs, and the Internet. Because the voice data is
transmitted over the IP network, IP telephony features lower cost and respectable
quality, especially for long distance calls. The KT101 is a SIP-based phone newly
launched by Technologies. Each KT101 has two Ethernet interfaces: the LAN interface
for access to a LAN or the Internet and the PC interface for connection to a PC. The
built-in network address translation (NAT) and dynamic host configuration protocol
(DHCP) functions enable a KT101 and the PCs connect to it to share the same
connection to a LAN or the Internet.
The comprehensive software features and superior voice coding performance enable
KT101 to provide you with cost-effective voice communication solutions. The LCD-and
Web-based configuration allows you to configure KT101 easily and conveniently.

7) Exit the configuration interface. When you exit the configuration interface, your KT101 will
restart to have the new settings take effect.
III. Configuring the forwarding mode
For a PC to access the LAN or Internet through your KT101, you must also configure the
forwarding mode of your KT101.The forwarding mode dictates how data is forwarded
between the LAN interface and the PC interface of your KT101, that is, the way for the PC
connected to your KT101 to obtain its IP address.
As shown in Table 3-2, the value of the Forward Mode argument can be Bridge (the
default), NAT, and Disable, which are described as follows:
•Bridge: Transparent bridge mode. In this mode, the PC interface of your KT101
functions as a Layer 2 switching port, and the LAN interface functions as a upstream
port. The PC connected to your KT101 accesses the LAN or the Internet in the same
way as your KT101. This mode is recommended for users who employ DHCP to
access a network.
•NAT: Network address translation (NAT) mode: In this mode, NAT and the built-in
DHCP server are enabled on your KT101. Your KT101 functions as a gateway with the
PC interface connected to the local network and the LAN interface connected to the
external network. For the PC connected to your KT101 to share the same connection
as your KT101 to access the LAN or the Internet, you only need to specify the PC to
obtain an IP address automatically. This mode is recommended for users who employ
PPPoE to access a network.
•Disable: In this mode, the PC interface of your KT101 is disabled, and the PC cannot
access the LAN or the Internet through your KT101, neither can it access the built-in
Web configuration pages of your KT101.
Follow these steps to configure the forwarding mode (refer to Table 3-1 for basic button
operations):
1) Enter the main menu.
2) Select [Networks] and confirm to enter its submenu.
3) When the LCD displays ―Type Password:‖, enter the password ―285#‖.

setting.
6) Exit the configuration interface.
3.2.2Configuring Protocol Parameters
Protocol configuration refers to settings of VoIP, which enable your KT101 to register with
the servers of your carrier. Before performing protocol configuration, consult your carrier for
the required protocol parameters.
Follow these steps to perform protocol configuration (Refer to Table 3-1 for basic button
operations.)
1) Enter the main menu.
2) Enter **# by pressing the corresponding buttons. At the prompt of ―Type Password:‖,
enter the password ―582#‖and confirm it.

Enable the VLAN tagging function only when you are sure that the network to which your

KT101 is connected supports this function. Otherwise, your KT101 may be unable to obtain
a network address, or you cannot place calls.
IV. Configuring DMZ and static port mapping
When operating in NAT mode, your KT101 denies requests initiated from external IP
networks. But some implementations require accessing the PC connected to the PC
interface of your KT101 from external networks to utilize the services provided by the
PC. In this case, you can satisfy the requirement by enabling static port mapping or
DMZ function.
Click the [DMZ] tab. The DMZ and static port map page appears (as shown in Figure
3-9), displaying items for setting the DMZ and static port mapping functions.
Note:
The configurations described below about DMZ and static port mapping are necessary only
when the forwarding mode is set to NAT.
Figure 3-9 Web configuration –DMZ and Static Port Map
1) Configuring DMZ
With the DMZ function enabled, you can specify a port number range. Packets
destined for the LAN interface of your KT101 with destination port numbers within
this range are forwarded to the corresponding ports of the host that is connected to
the PC interface of your KT101. (The host herein is referred to as a DMZ host.)
When you select Enable from the [DMZ Enable] drop-down list to enable the DMZ
function, the related configuration items appear, as shown in Figure 3-10.
