CHAPTER 1

Introducing the Prestige

This chapter introduces the main features and applications of the Prestige.

1.1 Prestige 2302R VoIP Station Gateway Series Overview

The Prestige 2302R VoIP (Voice over IP) station gateway lets you use traditional analog
telephones to make telephone calls over the Internet. The Prestige uses SIP (Session Initiation
Protocol), an internationally recognized standard for implementing VoIP.

You can call any landline or mobile telephone as well as IP telephones. You don’t need to
know if the recipient’s connection type is an IP, cellular or landline based service. Calls
received from IP telephones work exactly as you would expect from the traditional telephone
service.

The NAT and DHCP server features allow you to use an Ethernet hub or switch to set up a
private network and allow multiple computers to share a single Internet connection. The
Prestige also provides content filtering and a firewall for security.

The Prestige's web configurator allows easy management and configuration.

1.2 Prestige 2302RL VoIP Analog Telephone Adaptor with Lifeline

The Prestige 2302RL has all of the features of the Prestige 2302R and adds the PSTN (Public
Switched Telephone Network) lifeline feature. PSTN lifeline lets you have VoIP phone service
and PSTN phone service at the same time.

1.3 Features

Your Prestige is packed with a number of features that make it flexible and easy to use.

1

1. Some features documented in this user’s guide were not available in the Prestige 2302RL at the
time of writing.

Chapter 1 Introducing the Prestige 35

P-2302R Series User’s Guide

Firewall

The Prestige is a stateful inspection firewall with DoS (Denial of Service) protection. By
default, when the firewall is activated, all incoming traffic from the WAN to the LAN is
blocked unless it is initiated from the LAN. The Prestige firewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports and logs.

Content Filtering

The Prestige can also block access to web sites containing keywords that you specify. You can
define time periods and days during which content filtering is enabled and include or exclude a
range of users on the LAN from content filtering.

Bandwidth Management

Bandwidth management allows you to allocate network resources according to defined
policies. This policy-based bandwidth allocation helps your network to better handle real-time
applications such as Voice-over-IP (VoIP).

SIP ALG

The Prestige is a SIP Application Layer Gateway (ALG). It allows VoIP calls to pass through
NAT for devices behind the Prestige (such as a SIP-based VoIP software application on a
computer).

Any IP

The Any IP feature allows a computer to access the Internet and the Prestige without changing
the network settings (such as IP address and subnet mask) of the computer, when the IP
addresses of the computer and the Prestige are not in the same subnet.

10/100Mbps Auto-negotiating Fast Ethernet Interfaces

The auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions
and adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps
or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.

Auto-crossover 10/100 Mbps Ethernet Interfaces

The Ethernet interfaces automatically adjust to either a crossover or straight-through Ethernet
cable.

Reset Button

The Prestige reset button is built into the rear panel. Use this button to restore the factory
default password to 1234; IP address to 192.168.1.1, subnet mask to 255.255.255.0 and DHCP
server enabled with a pool of 32 IP addresses starting at 192.168.1.33.

36 Chapter 1 Introducing the Prestige

P-2302R Series User’s Guide

Multiple Telephones

You can connect more than one telephone to a Prestige telephone port. The Ringer
Equivalence Number (REN) is used to determine the number of devices that may be connected
to the telephone line. See the Table 138 on page 341 for the Prestige’s REN.

PSTN Lifeline

The Prestige 2302RL allows you to connect a PSTN line. You can receive incoming PSTN
phone calls even while someone else connected to the Prestige is making VoIP phone calls.
You can dial a (prefix) number to make an outgoing PSTN call. You can still make PSTN
phone calls if the Prestige 2302RL loses power.

Dynamic Jitter Buffer

The Prestige has a built-in adaptive, buffer that helps to smooth out the variations in delay
(jitter) for voice traffic. This helps ensure good voice quality for your conversations.

Multiple SIP Accounts

The Prestige allows you to simultaneously use multiple voice (SIP) accounts and assign them
to one or both telephone ports.

STUN

Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators
(STUN) allows SIP to pass through NAT routers.

Outbound Proxy

Some VoIP service providers use a SIP outbound server to handle voice calls. This allows the
Prestige to work from behind any type of NAT router and eliminates the need for STUN or a
SIP ALG (Application Layer Gateway).

Multiple Voice Channels

The Prestige can simultaneously handle multiple voice channels (telephone calls).
Additionally you can answer an incoming phone call on a VoIP account, even while someone
else is using the account for a phone call.

Voice Coding

The Prestige can use the following voice codecs (coder/decoders).

•G.711

•G.729

Chapter 1 Introducing the Prestige 37

P-2302R Series User’s Guide

Voice Activity Detection/Silence Suppression

Voice Activity Detection (VAD) reduces the bandwidth that a call uses by not transmitting
when you are not speaking.

Comfort Noise Generation

The Prestige generates background noise to fill moments of silence when the other device in a
call stops transmitting because the other party is not speaking (as total silence could easily be
mistaken for a lost connection).

Echo Cancellation

The Prestige supports G.168, an ITU-T standard for eliminating the echo caused by the sound
of your voice reverberating in the telephone receiver while you talk.

QoS (Quality of Service)

Quality of Service (QoS) mechanisms help to provide better service on a per-flow basis. The
Prestige supports Type of Service (ToS) and Differentiated Services (DiffServ). This allows
the Prestige to tag voice frames so they can be prioritized over the network.

Fax Tone Detection and Pass-through

The Prestige automatically detects fax messages and sends them over PCM G.711.

Auto-provisioning

Your voice service provider can automatically update your Prestige’s configuration via an
auto-provisioning server.

Auto Firmware Upgrade

The Prestige gives you the option to upgrade to a newer firmware version if it finds one during
auto-provisioning. Your voice service provider must have an auto-provisioning server and a
server set up with firmware in order for this feature to work.

Network Address Translation (NAT)

Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).

38 Chapter 1 Introducing the Prestige

P-2302R Series User’s Guide

Universal Plug and Play (UPnP)

Using the standard TCP/IP protocol, the Prestige and other UPnP enabled devices can
dynamically join a network, obtain an IP address and convey its capabilities to other devices
on the network.

DHCP (Dynamic Host Configuration Protocol)

DHCP (Dynamic Host Configuration Protocol) allows the individual client computers to
obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has
built-in DHCP server capability, enabled by default, which means it can assign IP addresses,
an IP default gateway and DNS servers to all systems that support the DHCP client. The
Prestige can also act as a surrogate DHCP server where it relays IP address assignment from
the actual real DHCP server to the clients.

Traffic Redirect

Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect
to the Internet, thus acting as an auxiliary backup when your regular WAN connection fails.

Port Forwarding

Use this feature to forward incoming service requests to a server on your local network. You
may enter a single port number or a range of port numbers to be forwarded, and the local IP
address of the desired server.

Dynamic DNS Support

With Dynamic DNS (Domain Name System) support, you can have a static hostname alias for
a dynamic IP address, allowing the host to be more easily accessible from various locations on
the Internet. You must register for this service with a Dynamic DNS service provider.

IP Multicast

Deliver IP packets to a specific group of hosts using IP multicast. IGMP (Internet Group
Management Protocol) is the protocol used to support multicast groups. The latest version is
version 2 (see RFC 2236); the Prestige supports both versions 1 and 2.

IP Alias

IP Alias allows you to partition a physical network into logical networks over the same
Ethernet interface. The Prestige supports three logical LAN interfaces via its single physical
Ethernet LAN interface with the Prestige itself as the gateway for each network.

Chapter 1 Introducing the Prestige 39

P-2302R Series User’s Guide

PPPoE

PPPoE (Point-to-Point Protocol over Ethernet) facilitates the interaction of a host with an
Internet modem to achieve access to high-speed data networks via a familiar "dial-up
networking" user interface.

RoadRunner Support

In addition to standard cable modem services, the Prestige supports Time Warner’s
RoadRunner Service.

Firmware Upgrades

Use the web configurator to upload updated firmware to your Prestige.

Embedded FTP and TFTP Servers

The Prestige’s embedded FTP and TFTP servers enable fast firmware upgrades as well as
configuration file backups and restoration.

SNMP

SNMP (Simple Network Management Protocol) is a protocol used for exchanging
management information between network devices. SNMP is a member of the TCP/IP
protocol suite. Your Prestige supports SNMP agent functionality, which allows a manager
station to manage and monitor the Prestige through the network. The Prestige supports SNMP
version one (SNMPv1) and version two (SNMPv2).

Logging and Tracing

Ease of Installation

Your Prestige is designed for quick, intuitive and easy installation. Physically, its compact size
lightness make it easy to position anywhere in your busy office. The Prestige is also wall
mountable.

1.5 Applications

Here are some examples of how you can use your Prestige.

1.5.1 Make Calls via Internet Telephony Service Provider

In a home or small office environment, you can use the Prestige to make and receive VoIP
telephone calls through an Internet Telephony Service Provider (ITSP).

Chapter 1 Introducing the Prestige 41

P-2302R Series User’s Guide

The following figure shows a basic example of how you would make a VoIP call through an
ITSP. You use your analog phone (A in the figure) and the Prestige (B) changes the call into
VoIP. The Prestige then sends your call through your modem or router (C) to the Internet and
the ITSP’s SIP server (D). The VoIP call server forwards calls to PSTN phones (F) through a
trunking gateway (E) to the PSTN network. The VoIP call server forwards calls to IP phones
(G) through the Internet.

Figure 2 Internet Telephony Service Provider Application

1.5.2 Make Calls via IP-PBX

If your company has an IP-PBX (Internet Protocol Private Branch Exchange), you can use the
Prestige to make and receive VoIP telephone calls through it.

In this example, you use your analog phone (A in the figure) and the Prestige (B) changes the
call into VoIP and sends it to the IP-PBX. The IP-PBX forwards calls to PSTN phones (C) to
the PSTN network. The IP-PBX forwards calls to IP phones (D) through an IP network (this
could include the Internet).

42 Chapter 1 Introducing the Prestige

Figure 3 IP-PBX Application

1.5.3 Make Peer-to-peer Calls

P-2302R Series User’s Guide

Use the Prestige to make a call to the recipient’s IP address without using a SIP proxy server
Peer-to-peer calls are also called “Point to Point” or “IP-to-IP” calls. You must know the
peer’s IP address in order to do this.

The following figure shows a basic example of how you would make a peer-to-peer VoIP call.
You use your analog phone (A in the figure) and the Prestige (B) changes the call into VoIP.
The Prestige then sends your call through your modem or router (C) and the Internet to the
peer VoIP device (D).

If you forget your password or cannot access the web configurator, you will need to reload the
factory-default configuration file or use the RESET button the back of the Prestige. Uploading
this configuration file replaces the current configuration file with the factory-default
configuration file. This means that you will lose all configurations that you had previously.
The password will also be reset to “1234”.

2.3.1 Procedure To Use The Reset Button

Make sure the PWR/VoIP LED is on (not blinking) before you begin this procedure.

P-2302R Series User’s Guide

4.3.1 Domain Name

The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave
this blank, the domain name obtained by DHCP from the ISP is used. While you must enter
the host name (System Name) on each individual computer, the domain name can be assigned
from the Prestige via DHCP.

4.3.2 DNS Server Address Assignment

Use DNS (Domain Name System) to map a domain name to its corresponding IP address and
vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is
extremely important because without it, you must know the IP address of a computer before
you can access it.

The Prestige can get the DNS server addresses in the following ways.

1 The ISP tells you the DNS server addresses, usually in the form of an information sheet,

when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS
Server fields in the SYSTEM General screen.

2 If the ISP did not give you DNS server information, leave the DNS Server fields in the

SYSTEM General screen set to 0.0.0.0 for the ISP to dynamically assign the DNS server

IP addresses.

4.5 Dynamic DNS

Dynamic DNS allows you to update your current dynamic IP address with one or many
dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You
can also access your FTP server or Web site on your own computer using a domain name (for
instance myhost.dhs.org, where myhost is a name of your choice) that will never change
instead of using an IP address that changes each time you reconnect. Your friends or relatives
will always be able to call you even if they don't know your IP address.

First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is
for people with a dynamic IP from their ISP or DHCP server that would still like to have a
domain name. The Dynamic DNS service provider will give you a password or key.

4.5.1 DynDNS Wildcard

Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the
same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use,
for example, www.yourhost.dyndns.org and still reach your hostname.

Note: If you have a private WAN IP address, then you cannot use Dynamic DNS.

The Prestige uses the following pre-defined list of NTP time servers if you do not specify a
time server or it cannot synchronize with the time server you specified.

Note: The Prestige can use this pre-defined list of time servers regardless of the Time

Protocol you select.

When the Prestige uses the pre-defined list of NTP time servers, it randomly selects one server
and tries to synchronize with it. If the synchronization fails, then the Prestige goes through the
rest of the list in order from the first one tried until either it is successful or all the pre-defined
NTP time servers have been tried.

5.1 LAN Overview

A Local Area Network (LAN) is a shared communication system to which many computers
are attached. A LAN is a computer network limited to the immediate area, usually the same
building or floor of a building. The LAN screens can help you configure a LAN DHCP server,
manage IP addresses, and partition your physical network into logical networks.

P-2302R Series User’s Guide

CHAPTER 5

LAN Setup

This chapter describes how to configure LAN settings.

5.2 IP Address and Subnet Mask

Similar to the way houses on a street share a common street name, so too do computers on a
LAN share one common network number.

Where you obtain your network number depends on your particular situation. If the ISP or
your network administrator assigns you a block of registered IP addresses, follow their
instructions in selecting the IP addresses and the subnet mask.

If the ISP did not explicitly give you an IP network number, then most likely you have a single
user account and the ISP will assign you a dynamic IP address when the connection is
established. If this is the case, it is recommended that you select a network number from

192.168.0.0 to 192.168.255.0 and you must enable the Network Address Translation (NAT)
feature of the Prestige. The Internet Assigned Number Authority (IANA) reserved this block
of addresses specifically for private use; please do not use any other number unless you are
told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254
individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other
words, the first three numbers specify the network number while the last number identifies an
individual computer on that network.

Once you have decided on the network number, pick an IP address that is easy to remember,
for instance, 192.168.1.1, for your Prestige, but make sure that no other device on your
network is using that IP address.

The subnet mask specifies the network number portion of an IP address. Your Prestige will
compute the subnet mask automatically based on the IP address that you entered. You don't
need to change the subnet mask computed by the Prestige unless you are instructed to do
otherwise.

Chapter 5 LAN Setup 71

P-2302R Series User’s Guide

5.3 DHCP Setup

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure the Prestige
as a DHCP server or disable it. When configured as a server, the Prestige provides the TCP/IP
configuration for the clients. If DHCP service is disabled, you must have another DHCP server
on your LAN, or else the computer must be manually configured.

5.3.1 IP Pool Setup

The Prestige is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool).
See the product specifications in the appendices. Do not assign static IP addresses from the
DHCP pool to your LAN computers.

These parameters should work for the majority of installations. If your ISP gives you explicit
DNS server address(es), read the embedded web configurator help regarding what fields need
to be configured.

5.4 LAN TCP/IP

The Prestige has built-in DHCP server capability that assigns IP addresses and DNS servers to
systems that support DHCP client capability.

5.4.1 Factory LAN Defaults

The LAN parameters of the Prestige are preset in the factory with the following values:

• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)

• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.

These parameters should work for the majority of installations. If your ISP gives you explicit
DNS server address(es), read the embedded web configurator help regarding what fields need
to be configured.

5.5 DNS Server Address

DNS (Domain Name System) is for mapping a domain name to its corresponding IP address
and vice versa. The DNS server is extremely important because without it, you must know the
IP address of a machine before you can access it. The DNS server addresses that you enter in
the DHCP setup are passed to the client machines along with the assigned IP address and
subnet mask.

72 Chapter 5 LAN Setup

P-2302R Series User’s Guide

There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP
to tell a customer the DNS server addresses, usually in the form of an information sheet, when
s/he signs up. If your ISP gives you the DNS server addresses, enter them in the DNS Server
fields in DHCP Setup, otherwise, leave them blank.

Some ISPs choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP
Control Protocol) after the connection is up. If your ISP did not give you explicit DNS
servers, chances are the DNS servers are conveyed through IPCP negotiation. The Prestige
supports the IPCP DNS server extensions through the DNS proxy feature.

If the Primary and Secondary DNS Server fields in the LAN Setup screen are not specified,
for instance, left as 0.0.0.0, the Prestige tells the DHCP clients that it itself is the DNS server.
When a computer sends a DNS query to the Prestige, the Prestige forwards the query to the
real DNS server learned through IPCP and relays the response back to the computer.

Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It
does not mean you can leave the DNS servers out of the DHCP setup under all circumstances.
If your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the
LAN Setup screen. This way, the Prestige can pass the DNS servers to the computers and the
computers can query the DNS server directly without the Prestige’s intervention.

5.6 RIP Setup

RIP (Routing Information Protocol) allows a router to exchange routing information with
other routers. The RIP Direction field controls the sending and receiving of RIP packets.
When set to:

• Both - the Prestige will broadcast its routing table periodically and incorporate the RIP
information that it receives.

• In Only - the Prestige will not send any RIP packets but will accept all RIP packets
received.

• Out Only - the Prestige will send out RIP packets but will not accept any RIP packets
received.

• None - the Prestige will not send any RIP packets and will ignore any RIP packets
received.

The Version field controls the format and the broadcasting method of the RIP packets that the
Prestige sends (it recognizes both formats when receiving). RIP-1 is universally supported;
but RIP-2 carries more information. RIP-1 is probably adequate for most networks, unless
you have an unusual network topology.

Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that
RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.

Chapter 5 LAN Setup 73

P-2302R Series User’s Guide

5.7 Multicast

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1
recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to
a group of hosts on the network - not everybody and not just 1.

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish
membership in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC

2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between IGMP
version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is
used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address

224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address

224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts
(including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP.
The address 224.0.0.2 is assigned to the multicast routers group.

The Prestige supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At
start up, the Prestige queries all directly connected networks to gather group membership.
After that, the Prestige periodically updates this information. IP multicasting can be enabled/
disabled on the Prestige LAN and/or WAN interfaces in the web configurator (LAN; WA N ).
Select None to disable IP multicasting on these interfaces.

5.8 Any IP

Traditionally, you must set the IP addresses and the subnet masks of a computer and the
Prestige to be in the same subnet to allow the computer to access the Internet (through the
Prestige). In cases where your computer is required to use a static IP address in another
network, you may need to manually configure the network settings of the computer every time
you want to access the Internet via the Prestige.

With the Any IP feature and NAT enabled, the Prestige allows a computer to access the
Internet without changing the network settings (such as IP address and subnet mask) of the
computer, when the IP addresses of the computer and the Prestige are not in the same subnet.
Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply
connect the computer to the Prestige and access the Internet.

The following figure depicts a scenario where a computer is set to use a static private IP
address in the corporate environment. In a residential house where a Prestige is installed, you
can still use the computer to access the Internet without changing the network settings, even
when the IP addresses of the computer and the Prestige are not in the same subnet.

74 Chapter 5 LAN Setup

Figure 19 Any IP Example

P-2302R Series User’s Guide

The Any IP feature does not apply to a computer using either a dynamic IP address or a static
IP address that is in the same subnet as the Prestige’s IP address.

Note: You must enable NAT/SUA to use the Any IP feature on the Prestige.

5.8.0.1 How Any IP Works

Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP
address) to a physical machine address, also known as a Media Access Control or MAC
address, on the local area network. IP routing table is defined on IP Ethernet devices (the
Prestige) to decide which hop to use,

The following lists out the steps taken, when a computer tries to access the Internet for the first
time through the Prestige.

1 When a computer (which is in a different subnet) first attempts to access the Internet, it

sends packets to its default gateway (which is not the Prestige) by looking at the MAC
address in its ARP table.

2 When the computer cannot locate the default gateway, an ARP request is broadcast on the

LAN.

3 The Prestige receives the ARP request and replies to the computer with its own MAC

address.

to help forward data along to its specified destination.

4 The computer updates the MAC address for the default gateway to the ARP table. Once

the ARP table is updated, the computer is able to access the Internet through the Prestige.

5 When the Prestige receives packets from the computer, it creates an entry in the IP

routing table so it can properly forward packets intended for the computer.

Chapter 5 LAN Setup 75

P-2302R Series User’s Guide

After all the routing information is updated, the computer can access the Prestige and the
Internet as if it is in the same subnet as the Prestige.

6.1 WAN Overview

Use this chapter to configure the settings for your WAN connection.

6.2 TCP/IP Priority (Metric)

The metric represents the "cost of transmission". A router determines the best route for
transmission by choosing a path with the lowest "cost". RIP routing uses hop count as the
measurement of cost, with a minimum of "1" for directly connected networks. The number
must be between "1" and "15"; a number greater than "15" means the link is down. The
smaller the number, the lower the "cost".

P-2302R Series User’s Guide

CHAPTER 6

WAN Screens

The metric sets the priority for the Prestige’s routes to the Internet. If the routes have the same
metric, the Prestige uses the following pre-defined priorities:

1 WA N: designated by the ISP or a static route (see Chapter 12 on page 141 for information

on static routes)

2 Traffic Redirect (see Section 6.9 on page 90)

For example, if WA N has a metric of "1" and Traffic Redirect has a metric of "2", the WA N
connection acts as the primary default route. If the WA N route fails to connect to the Internet,
the Prestige tries Traffic Redirect next.

6.4.2 PPPoE Encapsulation

The Prestige supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF
standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband
modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial­up connection using PPPoE.

Chapter 6 WAN Screens 83

P-2302R Series User’s Guide

For the service provider, PPPoE offers an access and authentication method that works with
existing access control systems (for example Radius).

One of the benefits of PPPoE is the ability to let you access one of multiple network services,
a function known as dynamic service selection. This enables the service provider to easily
create and offer new IP services for individuals.

Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires
no specific configuration of the broadband modem at the customer site.

By implementing PPPoE directly on the Prestige (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the Prestige does that part
of the task. Furthermore, with NAT, all of the LANs’ computers will have access.

disconnects from the PPPoE server.

6.5 WAN IP Address Assignment

Every computer on the Internet must have a unique IP address. If your networks are isolated
from the Internet, for instance, only between your two branch offices, you can assign any IP
addresses to the hosts without problems. However, the Internet Assigned Numbers Authority
(IANA) has reserved the following three blocks of IP addresses specifically for private
networks.

Table 18 Private IP Address Ranges

10.0.0.0 - 10.255.255.255

172.16.0.0 - 172.31.255.255

192.168.0.0 - 192.168.255.255

You can obtain your IP address from the IANA, from an ISP or have it assigned by a private
network. If you belong to a small organization and your Internet access is through an ISP, the
ISP can provide you with the Internet addresses for your local networks. On the other hand, if
you are part of a much larger organization, you should consult your network administrator for
the appropriate IP addresses.

Chapter 6 WAN Screens 85

P-2302R Series User’s Guide

Note: Regardless of your particular situation, do not create an arbitrary IP address;

always follow the guidelines above. For more information on address
assignment, please refer to RFC 1597, Address Allocation for Private Internets
and RFC 1466, Guidelines for Management of IP Address Space.

Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address
is assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.

The MAC address screen allows users to configure the WAN port's MAC address by either
using the factory default or cloning your computer’s MAC address. Choose Factory Default
to select the factory assigned default MAC Address.

Otherwise, click Spoof this computer's MAC address - IP Address and enter the IP address
of your computer. Once it is successfully configured, the address will be copied to the rom file
(ZyNOS configuration file). It will not change unless you change the setting or upload a
different ROM file.

The metric represents the "cost of transmission". A router determines the best route
for transmission by choosing a path with the lowest "cost". RIP routing uses hop count
as the measurement of cost, with a minimum of "1" for directly connected networks.
The number must be between "1" and "15"; a number greater than "15" means the link

This chapter provides background information on VoIP and SIP.

7.1 VoIP Introduction

VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This allows you
to make phone calls and send faxes over the Internet at a fraction of the cost of using the
traditional circuit-switched telephone network. You can also use servers to run telephone
service applications like PBX services and voice mail. Internet Telephony Service Provider
(ITSP) companies provide VoIP service. A company could alternatively set up an IP-PBX and
provide it’s own VoIP service.

P-2302R Series User’s Guide

CHAPTER 7

Introduction to VoIP

Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to
handle a telephone call. VoIP can use advanced voice coding techniques with compression to
reduce the required bandwidth.

7.2 Introduction to SIP

The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that
handles the setting up, altering and tearing down of voice and multimedia sessions over the
Internet.

SIP signaling is separate from the media for which it handles sessions. The media that is
exchanged during the session can use a different path from that of the signaling. SIP handles
telephone calls and can interface with traditional circuit-switched telephone networks.

7.2.1 SIP Identities

A SIP account uses an identity (sometimes referred to as a SIP address). A complete SIP
identity is called a SIP URI (Uniform Resource Identifier). A SIP account's URI identifies the
SIP account in a way similar to the way an e-mail address identifies an e-mail account. The
format of a SIP identity is SIP-Number@SIP-Service-Domain.

7.2.1.1 SIP Number

The SIP number is the part of the SIP URI that comes before the “@” symbol. A SIP number
can use letters like in an e-mail address ([e-mail] for example) or numbers
like a telephone number ([e-mail] for example).

Chapter 7 Introduction to VoIP 93

P-2302R Series User’s Guide

7.2.1.2 SIP Service Domain

The SIP service domain of the VoIP service provider is the domain name in a SIP URI. For
example, if the SIP address is [e-mail]
the SIP service domain.

7.2.2 SIP Call Progression

, then “VoIP-provider.com” is

2. Ringing

3. OK

7. OK

1 A sends a SIP INVITE request to B. This message is an invitation for B to participate in a

SIP telephone call.

2 B sends a response indicating that the telephone is ringing.

3 B sends an OK response after the call is answered.

4 A then sends an ACK message to acknowledge that B has answered the call.

5 Now A and B exchange voice media (talk).

6 After talking, A hangs up and sends a BYE request.

7 B replies with an OK response confirming receipt of the BYE request and the call is

terminated.

7.2.3 SIP Client Server

SIP is a client-server protocol. A SIP client is an application program or device that sends SIP
requests. A SIP server responds to the SIP requests.

When you use SIP to make a VoIP call, it originates at a client and terminates at a server. A
SIP client could be a computer or a SIP phone. One device can act as both a SIP client and a
SIP server.

94 Chapter 7 Introduction to VoIP

7.2.3.1 SIP User Agent

A SIP user agent can make and receive VoIP telephone calls. This means that SIP can be used
for peer-to-peer communications even though it is a client-server protocol. In the following
figure, either A or B can act as a SIP user agent client to initiate a call. A and B can also both
act as a SIP user agent to receive the call.

Figure 30 SIP User Agent

7.2.3.2 SIP Proxy Server

A SIP proxy server receives requests from clients and forwards them to another server.

In the following example, you want to use client device A to call someone who is using client
device C.

P-2302R Series User’s Guide

1 The client device (A in the figure) sends a call invitation to the SIP proxy server (B).

2 The SIP proxy server forwards the call invitation to C.

Figure 31 SIP Proxy Server

Chapter 7 Introduction to VoIP 95

P-2302R Series User’s Guide

7.2.3.3 SIP Redirect Server

A SIP redirect server accepts SIP requests, translates the destination address to an IP address
and sends the translated IP address back to the device that sent the request. Then the client
device that originally sent the request can send requests to the IP address that it received back
from the redirect server. Redirect servers do not initiate SIP requests.

In the following example, you want to use client device A to call someone who is using client
device C.

1 Client device A sends a call invitation for C to the SIP redirect server (B).

2 The SIP redirect server sends the invitation back to A with C’s IP address (or domain

name).

3 Client device A then sends the call invitation to client device C.

Figure 32 SIP Redirect Server

7.2.3.4 SIP Register Server

A SIP register server maintains a database of SIP identity-to-IP address (or domain name)
mapping. The register server checks your user name and password when you register.

7.2.4 RTP

When you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is used to
handle voice data transfer. See RFC 1889 for details on RTP.

96 Chapter 7 Introduction to VoIP

7.3 NAT

NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a
host in a packet. For example, the source address of an outgoing packet, used within one
network is changed to a different IP address known within another network.

In the simplest form, NAT changes the source IP address of a packet received from a device to
another IP address before forwarding the packet towards the destination. When the response
comes back, NAT translates the destination address back to the device’s IP address and
forwards it to the device.

NAT routers are commonly used to translate private (or internal) IP addresses in packet
headers to public (or external) IP addresses and vice versa. A NAT router maps a private IP
address and port pair to a public IP address and port, and whenever the NAT router receives a
packet with that public IP address and port, it knows how to reroute the packet back to the
private IP address and port.

NAT may be implemented on a device that is between your Prestige and the Internet.

P-2302R Series User’s Guide

7.3.1 NAT Example

See the following figure. The Prestige (X) sends packets to the Internet. The Prestige’s IP
address is 10.0.0.3. This is a private or internal IP address. The NAT router maps the private
source IP address to a public source IP address (a.b.c.d). The public source IP address is also
known as the external IP address.

Note: The NAT figures in this chapter use lower-case letters (like a.b.c.d for example)

to represent public IP addresses.

Figure 33 NAT: Outgoing

When the NAT router receives packets with destination address IP address a.b.c.d, the NAT
router changes a.b.c.d back to the private IP address 10.0.0.3 and sends it to the Prestige.

7.3.2 NAT Types

This section discusses the following NAT types that may be implemented on a router in front
of the Prestige.

• Full Cone

• Restricted Cone

• Port Restricted Cone

• Symmetric

The following table summarizes how these NAT types handle outgoing and incoming packets.
Read the following sections for more details and examples.

Table 22 NAT Types

PORT
RESTRICTED
CONE

Only external hosts
with an IP address
and port to which
the internal host
has already sent a
packet can send
packets to the
mapped external IP
address and port.

SYMMETRIC

A host on the external
network can only send
packets to the specific
mapped external IP
address and port that the
NAT router used in
sending a packet to the
external host’s IP address
and port.

The NAT router maps the
internal IP address and
port of each outgoing
packet to a different
external IP address and
port for each different
destination IP address
and port.

Incoming
Packets

Outgoing
Packets

FULL CONE

Any external host
can send packets to
the mapped
external IP address
and port.

The NAT router maps the internal IP address and port of all
outgoing packets to a single IP address and port on the
external network.

RESTRICTED
CONE

Only external hosts
with an IP address
to which the internal
host has already
sent a packet can
send packets to the
mapped external IP
address and port.

The examples in these NAT type sections describe NAT translation between internal (private)
and external (public) IP addresses.

98 Chapter 7 Introduction to VoIP

7.3.2.1 Full Cone NAT

In full cone NAT, the NAT router maps all outgoing packets from an internal IP address and
port to a single IP address and port on the external network. The NAT router also maps
packets coming to that external IP address and port to the internal IP address and port.

In the following example, the NAT router maps the source address of all packets sent from the
Prestige’s internal IP address 1 and port A to IP address 2 and port B on the external network.
The NAT router also performs NAT on all incoming packets sent to IP address 2 and port B
and sends them to IP address 1, port A.

Figure 35 Full Cone NAT Example

P-2302R Series User’s Guide

7.3.2.2 Restricted Cone NAT

As in full cone NAT, a restricted cone NAT router maps all outgoing packets from an internal
IP address and port to a single IP address and port on the external network. In the following
example, the NAT router maps the source address of all packets sent from internal IP address 1
and port A to IP address 2 and port B on the external network.

The difference from full cone NAT is in how the restricted cone NAT router handles packets
coming in from the external network. A host on the external network (IP address 3 or IP
address 4 for example) can only send packets to the internal host if the internal host has
already sent a packet to the external host’s IP address.

A Prestige with IP address 1 and port A sends packets to IP address 3 and IP address 4. The
NAT router changes the Prestige’s IP address to 2 and port to B.

Both 4, D and 4, E can send packets to 2, B since 1, A has already sent packets to 4. The NAT
router will perform NAT on the packets from 4, D and 4, E and send them to the Prestige at IP
address 1, port A. Packets have not been sent from 1, A to 3 or 5, so 3 and 5 cannot send
packets to 1, A.

Chapter 7 Introduction to VoIP 99

P-2302R Series User’s Guide

Figure 36 Restricted Cone NAT Example

7.3.2.3 Port Restricted Cone NAT

As in full cone NAT, a port restricted cone NAT router maps all outgoing packets from an
internal IP address and port to a single IP address and port on the external network. In the
following example, the NAT router maps the source address of all packets sent from internal
IP address 1 and port A to IP address 2 and port B on the external network.

The difference from full cone and restricted cone NAT is in how the port restricted cone NAT
router handles packets coming in from the external network. A host on the external network
(IP address 3 and Port C for example) can only send packets to the internal host if the internal
host has already sent a packet to the external host’s IP address and port.

A Prestige with IP address 1 and port A sends packets to IP address 3, port C and IP address 4,
port D. The NAT router changes the Prestige’s IP address to 2 and port to B.

Since 1, A has already sent packets to 3, C and 4, D, they can send packets back to 2, B and the
NAT router will perform NAT on them and send them to the Prestige at IP address 1, port A.

Packets have not been sent from 1, A to 4, E or 5, so they cannot send packets to 1, A.
