Section 1
Overview
This section provides an overview of the V-SIPGW16
card.
Document Version 2009-12 Programming Manual for Virtual SIP CO Line Card 3

1.1 Information about IP Telephony Service
The Virtual 16-Channel SIP CO Line Card (V-SIPGW16) is a virtual CO line card which is designed to be easily
integrated into an Internet Telephony Service provided by an ITSP (Internet Telephony Service Provider).
As a major SIP Provider, an ITSP provides its telephony service partly through the conventional telephone
network (e.g., ISDN and Mobile), which is fee-based. An ISP (Internet Service Provider), another major SIP
Provider, does not provide telephone connection itself. However, providing its users with Internet access, an
ISP provides voice communication on the Internet for free. In this way, with VoIP technology based on the SIP
protocol, the cost of voice communication can be much cheaper than conventional telephone networks.
The maximum number of V-SIPGW16 cards that can be installed in the virtual CO line slots of the PBX is one
for the KX-NCP500 and two for the KX-NCP1000.
The channel capacity of the card allows KX-NCP500 users to connect to up to 8 different ISP/ITSPs and allows
KX-NCP1000 users to connect to up to 32 different ISP/ITSPs.

Note
•VoIP communication using the V-SIPGW16 card may deteriorate depending on the ITSP being used.
•VoIP communication using the V-SIPGW16 card may deteriorate depending on the network conditions.
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. 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 PBX 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 PBX, not the global IP address of the router. Therefore, if the SIP server receives
a SIP message from the PBX and sends a message back to the PBX using the address stored in the SIP
message, the packet information will not reach the PBX.
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 PBX.
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
3.3.1 Main, NAT Traversal).
The V-SIPGW16 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 V-SIPGW16 card and the
SIP Server (SIP Receiver) via a router with NAT enabled.

1.1 Information about IP Telephony Service

1.2 Important Notice for Subscription and Installation
1.2.1 Port Requirements
Required Ports for Each Channel
When configuring a router with NAT enabled, you need to secure a certain number of ports for each SIP and
RTP/RTCP channel. For RTP/RTCP, the number of required ports is double the number of activated SIP CO
lines (Ch). For SIP signaling, the number of required ports is always one regardless of the number of activated
SIP CO lines (Ch).
<Example>
If 4 SIP CO line channels are activated, you need the following number of ports:
Protocol Type Required Port
RTP 4
RTCP 4
SIP 1
Total 9
1.2.2 Firewall Requirements
If the VoIP network contains a firewall, you must configure the firewall to allow VoIP packets to pass through
certain ports of the ports listed below without being blocked by filtering. The ports for which you need to
configure the firewall may vary depending on the network conditions.
For more information, consult your network administrator.

Document Version 2009-12 Programming Manual for Virtual SIP CO Line Card 7
1.2.2 Firewall Requirements

Router Requirements
•Port Forwarding:
It may be necessary to set the NAT router so that it forwards the incoming packets to the IP address of the
V-SIPGW16 card if all of the following conditions are met:
–the PBX uses a STUN server;
–a V-SIPGW16 card is located under a NAT router;
–incoming packets are routed to a SIP Client port or NAT Voice (RTP) UDP port indicated in the [IP
Packets to V-SIPGW16 Card] table above.
•SIP-NAT Feature:
When a V-SIPGW16 card is located under a NAT router that supports the SIP-NAT feature*1, it is
recommended to disable this feature.
*1 When NAT is enabled, the router translates the IP address stored in the IP header and the port number stored in the UDP header.
When SIP-NAT is enabled, the router also translates the IP address and port number stored in SIP messages.
1.2.3 Bandwidth Requirements
When using the V-SIPGW16 card, you must ensure that the WAN has enough bandwidth to support VoIP
communications. Refer to the table below and ensure that the sum of the required bandwidth for each channel
is smaller than the amount the WAN (e.g., ADSL network) can provide.
Note that the amount in the table is only a guide. Subscribe to a network that has enough bandwidth. If the
amount of bandwidth required for VoIP communications is larger than what the network can accommodate,
speech quality will be compromised.
Required Bandwidth for Each Channel
The required bandwidth depends on what combination of codecs and packet sending interval is used. Keep
in mind the following points about the type of codec and packet sending interval, in terms of the speech quality:
•The speech quality of the codecs varies as follows: G.711 (High), G.729A (Low)
•The shorter the packet sending interval, the higher the speech quality.
•The higher the speech quality the V-SIPGW16 card provides, the more bandwidth the WAN requires.
Codec
Packet Sending Interval
10 ms 20 ms 30 ms 40 ms 50 ms 60 ms
G.711 110.4 kbps 87.2 kbps 79.5 kbps 75.6 kbps 73.3 kbps 71.7 kbps
G.729A 54.4 kbps 31.2 kbps 23.5 kbps 19.6 kbps 17.3 kbps 15.7 kbps

The IP telephones will not operate properly if these IP addresses are changed.
•A DHCP server must be able to use a "client identifier" option specified by RFC 2131.
•The PBX will not start properly if the IP addresses cannot be assigned automatically by the
DHCP server when DHCP Client is set to Enable. In this case, you need to consult your
network administrator because the DHCP server on your network may not be running or a
network failure may have occurred. If the DHCP server cannot be available, change the
DHCP Client setting to Disable and set fixed IP addresses, then restart the PBX.
To change the DHCP Client setting, connect the PC with an RS-232C cross cable or Ethernet
straight cable. When connecting the PC with an Ethernet straight cable, make sure the PBX
is disconnected from the LAN and then connect the PC with an Ethernet straight cable using
