1.1 Information about IP Telephony Service

The Virtual 16-Channel SIP Trunk Card ( 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 of two V-SIPGW16 cards can be installed to the virtual trunk slots of the PBX. Therefore, the channel capacity of the card allows users to connect to up to 32 each different ISP/ITSPs.

V-SIPGW16) is a virtual trunk card which is designed to be easily

V-SIPGW16 Connection Outline

The following diagram illustrates a simple VoIP network connecting the V-SIPGW16 card to the Internet.

Requirements for Internet Telephony Service

• You need to subscribe with an ISP for Internet connection.

• You

need to subscribe with an ITSP for telephone connection. The ISP and ITSP may be part of the same

company.

• VoIP

communication using the V-SIPGW16 card may deteriorate depending on the ITSP being used.

1.1 Information about IP Telephony Service

• 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 recognises 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.

1.2.2 Firewall Requirements

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 (Ch). For SIP signalling, the number of required ports is always one regardless of the number of activated SIP trunks (Ch). <Example> If 4 SIP trunk channels are activated, you need the following number of ports:

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.

1.2.3 Bandwidth Requirements

Router Requirements

• Port Forwarding:

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.

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.729 (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.

Notice

• Do

not change the IP addresses of the IPCMPR/IPCEMPR and DSP cards once IP telephones are registered to the PBX using these IP addresses. 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

192.168.0.101 for the IP address of the IPCMPR/IPCEMPR card.
