1.1 Information about IP Telephony Service
The KX-TDA5450 SIP-GW4 card is a CO line card which is designed to be easily integrated into Internet
Telephony Service provided by an ITSP (Internet Telephony Service Provider). With VoIP technology based
on the SIP protocol, the cost of voice communication can be much cheaper than conventional telephone
networks.
Mounting the 4-channel VoIP DSP (SIP-DSP4) card on a SIP-GW4 card can enhance the channel capacity to
a total of 8 channels.

The following diagrams illustrate a simple VoIP networks connecting the SIP-GW4 card to the Internet or LAN.

1.1 Information about IP Telephony Service

Note
If you connect the SIP-GW4 card to a LAN network and enable the DHCP Client feature, be sure to connect
the card to the same LAN network as the DHCP server so that the card can access the DHCP server
directly, not via a router.

Requirements for Internet Telephony Service
•You need to subscribe with an ISP (Internet Service Provider) for Internet connection.
•You need to subscribe with an ITSP for telephone connection. The ISP and ITSP may be part of the same
company.
Note
•The SIP-GW4 card may not function properly depending on the ITSP being used.
•The performance of the SIP-GW4 card may deteriorate depending on the network conditions.
•If you access the Internet from the PC connected to the LAN port of the SIP-GW4 card and send or
receive large amounts of data, there may be an adverse affect on voice communication. In addition,
for security reasons, it is recommended not to access the Internet from the PC connected to the card.
Therefore, it is recommended to connect a PC exclusively for maintenance of the card to the LAN port
of the SIP-GW4 card.
DNS (Domain Name System)
A DNS server normally provides the name resolution service for your computer. As domain names are
alphabetic, they are easier to remember. The Internet, however, is based on IP addresses.
Document Version 2008-10 Installation Manual 7
1.1 Information about IP Telephony Service

Therefore, every time a domain name is used, a DNS server must translate the name into the corresponding
IP address, and vice versa. For example, the domain name www.example.com may be translated to
192.0.34.166. If one DNS server does not know how to translate a particular domain name, it asks another
one, and so on, until the correct IP address is returned.
NAT (Network Address Translation) Traversal
When NAT/NAPT (Network Address Port Translation) is enabled, the router translates a local IP address from
the SIP-GW4 card into a global IP address. However, the router with NAT enabled does not translate local IP
addresses stored in SIP messages into global IP addresses.
Therefore, the address which the SIP Server recognizes as the destination IP address to reply to is actually
the local IP address of the SIP-GW4 card, not the global IP address of the router. Therefore, if the SIP server
receives a SIP message from the SIP-GW4 card and sends a message back to the SIP-GW4 card using the
address stored in the SIP message, the packet information will not reach the SIP-GW4 card.
STUN Servers function to solve the global IP address problem under certain NAT conditions, for example, in
case of full duplex communication. A STUN Server, used alongside the SIP Server, finds out the global IP
address of the router with NAT enabled. With the STUN feature enabled, the packet information sent by the
SIP Server is able to "traverse" NAT and reach the SIP-GW4 card.
The settings can be configured to specify whether to enable the NAT Traversal feature for each ISP/ITSP. In
addition, the NAT Traversal method can be selected from "STUN" and "Fixed IP Address" (refer to 3.4.3 NAT
Traversal).

1.1 Information about IP Telephony Service

The SIP-GW4 card may require the NAT Traversal feature to be enabled to connect to the WAN via a router.
The following diagram illustrates how VoIP communication is enabled between the SIP-GW4 card and the SIP
Server (SIP Receiver) via a router with NAT enabled.
