CHAPTER 1
Understanding Your IP1200C
Congratulations! You have selected the advanced Voice over IP Telephony product.
IP1200C Gateway is an innovative Voice over Internet Protocol (VoIP) solution for
enterprises or call booth operators. IP1200C is a new generation VoIP gateway carries
voice traffic over TCP/IP networks. By deploying IP1200C, you can consolidate voice
and data traffic for more efficient use of bandwidth and reduce your international and
long-distance phone call charges.
IP1200C is an embedded gateway combining hardware, software and operating system
for plug-and-play simplicity. It provides a seamless interface between TCP/IP networks
and the Public Switched Telephone Network (PSTN). Users can place Internet calls to any
regular phone numbers in the world. IP1200C is an outstanding gateway bringing you
the most cost-effective communications.
4 Chapter 1 Understanding Your IP1200C
Overview
In the past, real-time voice communication can only be done on the PSTN. With the circuit switched technology,
every call takes up a dedicated bandwidth. End-to-end calls are established on the basis of a sequence of digits,
and the PSTN dedicates a physical path between callers. The telephone equipment establishes the call path at the
beginning of a call and occupies the dedicated path till the end of the call.
Compared to the PSTN, an Internet Protocol (IP) network has a packet-switched architecture. Data is transmitted
in packets, and the path from end to end can vary within an established session. The data packets also contain the
destination IP address information, with which packets are routed. As networking environments change, routing
devices are updated with dynamic protocols.
IP1200C is a high performance embedded VoIP Gateway that transmits voice over packet switched networks and
route it to circuit switched networks.
All-in-one Design
IP1200C contains its own processor, memory, and network interface; it works independently and intelligently!
Simply connect it to your IP network and PSTN or phone sets, and then you are ready to talk via the Internet. All
of the communication costs will be eliminated except the local networks connection charge. IP1200C is the most
convenient embedded VoIP gateway for users to make Internet phone calls without the hassle of changing the
existing infrastructure.
Device-to-Phone Operation Mode
IP1200C is a reliable bridge between two different locations. The FXO/FXS telephone interface provides the
system with an ultra flexible PSTN connection. Supported by DSG Global Internet Telephony Network, users can
make phone calls to any regular phone numbers in the world.

Plug the power adapter into a power outlet. Plug the DC adapter connector into IP1200C power socket at the back
labeled PWR. The LED light labeled PWR will light up and keep blinking.
Note: Please use ESD-preventive tools and maintain safety with electricity when you plug the power cord.
Connecting the Line Ports
For IP1200C FXO Model
IP1200C provides FXO interface. When power on, the LED color is red. The FXO module is designed for
connecting to C.O. lines from your telephone company (PSTN) or a PBX extension-side. Plug a telephone line
connected to PSTN or a PBX’s extension-side into a FXO RJ11 port.
If you connect the IP1200C FXO ports to the PBX’s extension side, each port will obtain an extension number, just
like the other extensions in your office.
For IP1200C FXS Model
IP1200C provides FXS interface. When power on, the LED color is green. The FXS module is designed for
connecting to analog telephone sets or a PBX trunk-side. Plug a telephone line connected to an analog phone or a
PBX’s trunk-side into a FXS RJ11 port
If you connect the IP1200C FXS ports to the PBX’s trunk side, each port will obtain an access code or can be
viewed from phone sets’ line indicators.
Note: Misplacing FXO equipment into FXS interface and vice versa may damage IP1200C. Be sure that the
FXO/FXS interfaces are connected to the adequate telephone lines and equipment.
Connecting to the TCP/IP Network
Plug a network cable connected to your Ethernet into RJ45 jack labeled ETHERNET.
It is recommended that you provide a permanent Internet connection for IP1200C, such as connections from
Leased Line, xDSL (not include PPPoE) or Cable Modem, and assign a static IP address (real IP address if
applicable) to IP1200C.
Chapter 2 Installing Your IP1200C 9
If your network is behind NAT or firewall, you can assign a pseudo IP address to your IP1200C. IP1200C has
preset UDP and TCP ports allowing communication to get through NATs and firewalls. In general, you do not
need to open ports on your network gateway or router.
If your network is in the DHCP environment, you can enable IP1200C DHCP function to obtain an IP address
automatically.
Note: When you encounter one-way voice cannot be heard problem, the reason might be that the specific
communication ports for IP1200C been blocked. Check if the specific ports on your router are opened to
IP1200C. For 4-port IP1200C, open TCP 1100 port and UDP 1101-1104 ports. For 8-port IP1200C, open TCP
1100 port and UDP 1101-1108 ports.

TCP/IP Setup
Before you start using your IP1200C, you must have an Internet access line from your local ISP. It could be xDSL,
Cable Modem access, or Leased Line. You will be given the information of IP Address, Gateway IP and Subnet
Mask from your network administrator. If your network is in the DHCP environment, you may enable the DHCP
function.
IP Address
IP Address is an identifier for device on a TCP/IP network. Your IP Address allows other VoIP devices on the
Internet to find your location. The format of an IP address is a 32-bit numeric address written as four numbers
separated by periods.
Step 1 At the prompt displays Select the option to setup:, input <1> and press ENTER to edit IP Address.
Step 2 At the prompt displays New IP Address (press ESC to exit):, input the IP Address <xxx.xxx.xxx.xxx>
obtained from your ISP or network administrator and then press ENTER.

Press any key to continue...
IP1200C supports the Internet connection from Leased Line, xDSL (not include PPPoE) or Cable Modem. To
ensure the performance of IP1200C, it is recommended that you assign a static and real IP address to IP1200C.
If your network is behind NAT or firewall, you can assign a pseudo IP address to your IP1200C. IP1200C can go
through NATs and firewalls with its preset communication ports. In general, you do not need to open ports on
your network gateway or router.
Note: If your network is in the DHCP environment, please skip the IP address, gateway IP and subnet mask
settings and go to (5) DHCP and enable it.
Note: When you encounter one-way voice cannot be heard problem, the reason might be that the specific
communication ports for IP1200C been blocked. Make sure your router or ISP does not block the specific
ports as follows. For 4-port IP1200C, the preset ports are TCP 1100 port and UDP 1101-1104 ports; for 8-port
IP1200C, they are TCP 1100 port and UDP 1101-1108 ports.
Gateway IP Address
The purpose of a gateway is to link two different types of networks. For example, the Gateway IP Address for a
LAN to connect to the WAN is the IP Address of the router.
Step 1 At the prompt displays Select the option to setup:, input <2> and press ENTER to edit Gateway IP.
Step 2 At the prompt displays New Gateway IP (press ESC to exit):, input the Gateway IP <xxx.xxx.xxx.xxx>

Select the option to setup: 4
New DNS (press ESC to exit): 168.6.1.1
Press any key to continue...
DHCP (Required for DHCP Environment)
IP1200C supports DHCP (Dynamic Host Configuration Protocol), a protocol for assigning dynamic IP addresses
to devices on a network. Because a device can be assigned a different IP address every time when it connects to
the network, a new device can be added to a network without the hassle of manually assigning it a unique IP
address.
Step 1 If your network supports DHCP, at the prompt displays Select the option to setup:, input <5> and press
ENTER to edit DHCP function.
Step 2 After the prompt displays New DHCP (0:Off, 1: On, press ESC to exit):, input <1> to enable or <0> to
disable DHCP function and then press ENTER.
