CHAPTER 1

Introducing the Prestige

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

1.1 Prestige VoIP Analog Telephone Adaptor Overview

The Prestige is a SIP-based VoIP analog telephone adaptor (ATA). Sending voice signals over
the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an
internationally recognized standard for implementing VoIP.

The Prestige allows you to use a traditional analog telephone to make and receive Voice over
IP calls. 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 Prestige’s two Ethernet ports allow you to connect the Prestige to your LAN and connect
your computer to the Prestige. This way your computer can still access the LAN without
adding an extra Ethernet switch.

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

1.2 Prestige 2002L VoIP Analog Telephone Adaptor with Lifeline

The Prestige 2002L has all of the features of the Prestige 2002 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.

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.

1. Some features documented in this user’s guide were not available in the Prestige 2002L at the
time of writing.

1

Chapter 1 Introducing the Prestige 23

P-2002 Series User’s Guide

Auto-crossover 10/100 Mbps Ethernet Interfaces

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

PSTN Lifeline

The Prestige 2002L has a LINE port for connecting 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 2002L loses power.

REN

A Ringer Equivalence Number is used to determine the number of devices that may be
connected to the telephone line. The Prestige can support three devices per telephone port.

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.

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

Voice Activity Detection/Silence Suppression

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

24 Chapter 1 Introducing the Prestige

P-2002 Series User’s Guide

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) tagging and Differentiated Services (DiffServ)
tagging. 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.

Manual Firmware Upgrades

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

Ease of Installation

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

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).

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. 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.

26 Chapter 1 Introducing the Prestige

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).

P-2002 Series User’s Guide

Figure 3 IP-PBX Application

1.5.3 Make Peer-to-peer Calls

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.

Chapter 1 Introducing the Prestige 27

P-2002 Series User’s Guide

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.

28 Chapter 1 Introducing the Prestige

Introducing the Web

This chapter describes how to access the Prestige web configurator and provides an overview
of its screens.

2.1 Web Configurator Overview

The web configurator is an HTML-based management interface that allows easy Prestige
setup and management via Internet browser. Use Internet Explorer 6.0 and later or Netscape
Navigator 7.0 and later versions. The recommended screen resolution is 1024 by 768 pixels.

P-2002 Series User’s Guide

CHAPTER 2

Configurator

In order to use the web configurator you need to allow:

• Web browser pop-up windows from your device. Web pop-up blocking is enabled by
default in Windows XP SP (Service Pack) 2.

• JavaScripts (enabled by default).

• Java permissions (enabled by default).

See the Troubleshooting chapter if you want to make sure these functions are allowed in
Internet Explorer or Netscape Navigator.

2.2 Accessing the Prestige Web Configurator

Note: If your LAN has multiple Prestige 2002s, you may need to disconnect your

Prestige’s LAN port to avoid accessing the wrong Prestige. Reconnect the LAN port
after the Login screen displays.

1 Make sure your Prestige hardware is properly connected and prepare your computer/

computer network to connect to the Prestige (refer to the Quick Start Guide).

2 Launch your web browser.

3 Enter the Prestige’s management IP address (default 192.168.5.1) or IP address. The

Prestige 2002 has a management IP address since by default the Prestige is set to receive
a dynamically assigned IP address and thus has no default IP address. Use the Prestige’s
management IP address or its IP address (after it receives one). If your computer is
directly connected to the Prestige, make sure your computer’s IP address is in the same
subnet as the Prestige’s IP address or management IP address that you want to access.

page 32).

Note: The Prestige automatically logs you out if the management session is idle for
five minutes. Simply log back in if this happens to you.

30 Chapter 2 Introducing the Web Configurator

2.3 Resetting the Prestige

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 on the back of the Prestige.
Uploading this configuration file replaces the current configuration file with the factory­default 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.

1 Press the RESET button for five to ten seconds (release it when the PWR/VoIP LED

begins to blink). When the PWR/VoIP LED starts blinking, the defaults have been
restored and the Prestige restarts. Otherwise, go to step 2.

2 Disconnect and reconnect the Prestige’s power.

3 Wait for the PWR LED to stop blinking and stay on steady.

4 Press the RESET button for five to ten seconds (release it when the PWR/VoIP LED

begins to blink). When the PWR/VoIP LED starts blinking, the defaults have been
restored and the Prestige restarts. Otherwise, go to step 2.

3.5 Pre-defined NTP Time Servers List

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.

Ethernet Screens

This chapter describes how to configure the Prestige’s Ethernet and management IP addresses
settings.

4.1 ETHERNET Overview

The Prestige has two Ethernet ports. Connect the LAN Ethernet port to a cable/DSL modem or
router or an Ethernet LAN switch, which in turn connects you to the Internet or your
company’s IP-PBX. Connect the PC Ethernet port to your computer. The Prestige bridges
network traffic between the two Ethernet ports so your computer can still access the Internet or
the company LAN. Both Ethernet ports use the same IP address and subnet mask.

4.1.1 IP Address and Subnet Mask

P-2002 Series User’s Guide

CHAPTER 4

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 the ISP should assign you a
dynamic IP address when the connection is established.

Once you have decided on the network number, pick an IP address that is easy to remember,
for instance, 192.168.1.20, 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.

4.1.2 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.

• 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.

• If the ISP did not give you DNS server information, leave the DNS Server fields set to

0.0.0.0 for the ISP to dynamically assign the DNS server IP addresses.

Chapter 4 Ethernet Screens 41

P-2002 Series User’s Guide

4.1.3 PPPoE Encapsulation

Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an
IETF (Internet Engineering Task Force) draft standard specifying how a host personal
computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to
achieve access to high-speed data networks.

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

One of the benefits of PPPoE is the ability to let end users 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 specific users.

Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber’s site.

For more information on PPPoE, see Appendix D on page 131.

4.2 Configuring Ethernet

Click ETHERNET in the navigation panel to display the ETHERNET screen. Use the
ETHERNET Ethernet screen to configure the Prestige’s Ethernet interfaces with Internet

account information from your ISP. Your ISP may have already configured some of the fields
for you.

You can manage the Prestige through the Ethernet IP address, but you may not always know
the Prestige’s IP address (especially if the IP address is dynamic). Use the Mgnt Port screen
(see Figure 13 on page 44) to configure a static IP address that you use to access the Prestige
for management.

This chapter provides background information on VoIP and SIP.

5.1 Introduction to VoIP

VoIP 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 circuit­switched 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.

Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to

Introduction to VoIP

5.2 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.

5.2.1 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.

5.2.1.1 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).

5.2.1.2 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.

5.2.2 SIP Call Progression

The following figure displays the basic steps in the setup and tear down of a SIP call. A calls
B.

Table 10 SIP Call Progression

A B

1. INVITE

4. ACK

5.Dialogue (voice traffic)

6. BYE

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

SIP telephone call.

2. Ringing

3. OK

7. OK

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.

5.2.3 SIP Servers

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.

5.2.3.1 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.

46 Chapter 5 Introduction to VoIP

Figure 14 SIP User Agent

5.2.3.2 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.

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 15 SIP Proxy Server

P-2002 Series User’s Guide

5.2.3.3 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.

Chapter 5 Introduction to VoIP 47

P-2002 Series User’s Guide

Figure 16 SIP Redirect Server

5.2.3.4 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.

5.2.4 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.

5.3 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.

48 Chapter 5 Introduction to VoIP

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

5.3.1 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 17 NAT: Outgoing

P-2002 Series User’s Guide

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.

Figure 18 NAT: Incoming

5.3.2 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

Chapter 5 Introduction to VoIP 49

P-2002 Series User’s Guide

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

Table 11 NAT Types

FULL CONE

Incoming
Packets

Outgoing
Packets

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.

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

5.3.2.1 Full Cone NAT

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.

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.

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.

50 Chapter 5 Introduction to VoIP

Figure 19 Full Cone NAT Example

5.3.2.2 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.

P-2002 Series User’s Guide

Figure 20 Restricted Cone NAT Example

Chapter 5 Introduction to VoIP 51

P-2002 Series User’s Guide

5.3.2.3 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.

Figure 21 Port Restricted Cone NAT Example

5.3.2.4 Symmetric NAT

The full, restricted and port restricted cone NAT types use the same mapping for an outgoing
packet’s source address regardless of the destination IP address and port. In symmetric NAT,
the mapping of an outgoing packet’s source address to a source address in another network is
different for each different destination IP address and port.

In the following example, the NAT router maps the Prestige’s source address IP address 1 and
port A to IP address 2 and port B on the external network for packets sent to IP address 3 and
port B. The NAT router uses a different mapping (IP address 2 and port M) when the Prestige
sends packets to IP address 4 and port D.

A host on the external network (IP address 3 and port C for example) can only send packets to
the internal host via the external IP address and port that the NAT router used in sending a
packet to the external host’s IP address and port. So in the example, only 3, C is allowed to
send packets to 2, B and only 4, D is allowed to send packets to 2, M.

52 Chapter 5 Introduction to VoIP

Figure 22 Symmetric NAT

5.4 NAT and SIP

Some NAT routers are not SIP-friendly and will stop your voice sessions.

The Prestige must register its public IP address with a SIP register server. If there is a NAT
router between the Prestige and the SIP register server, the Prestige probably has a private IP
address. The Prestige lists its IP address in the SIP message that it sends to the SIP register
server. NAT does not translate this IP address in the SIP message. The SIP register server gets
the Prestige’s IP address from inside the SIP message and maps it to your SIP identity. If the
Prestige has a private IP address listed in the SIP message, the SIP server cannot map it to your
SIP identity.

P-2002 Series User’s Guide

A SIP ALG (Application Layer Gateway), the fake WAN address on SIP and RTP, STUN, or
outbound proxy features allow the Prestige to use its public IP address in the SIP messages.

5.4.1 SIP ALG

Some NAT routers may include a SIP Application Layer Gateway (ALG). A SIP ALG allows
SIP calls to pass through NAT by examining and translating IP addresses embedded in the
data stream. When the Prestige registers with the SIP register server, the SIP ALG translates
the Prestige’s private IP address inside the SIP data stream to a public IP address. You do not
need to use STUN or an outbound proxy if your Prestige is behind a SIP ALG.

5.4.2 Use NAT Address on SIP and RTP

If you know the NAT router’s public IP address and SIP port number, you can use the Use
NAT feature to manually configure the Prestige to use a them in the SIP messages. This
eliminates the need for STUN or a SIP ALG.

You must also configure the NAT router to forward traffic with the SIP port number to the
Prestige.

Chapter 5 Introduction to VoIP 53

P-2002 Series User’s Guide

5.4.3 STUN

STUN (Simple Traversal of User Datagram Protocol (UDP) through Network Address
Translators) allows the Prestige to find the presence and types of NAT routers and/or firewalls
between it and the public Internet. STUN also allows the Prestige to find the public IP address
that NAT assigned, so the Prestige can embed it in the SIP data stream. STUN does not work
with symmetric NAT routers (see Section 5.3.2.4 on page 52) or firewalls. See RFC 3489 for
details on STUN.

The following figure shows how STUN works.

1 The Prestige (A) sends SIP packets to the STUN server.

2 The STUN server finds the public IP address and port number that the NAT router used

on the Prestige’s SIP packets and sends them to the Prestige.

3 The Prestige uses the public IP address and port number in the SIP packets that it sends to

the SIP server.

Figure 23 STUN

5.4.4 Outbound Proxy

Your VoIP service provider may host a SIP outbound proxy server to handle all of the
Prestige’s VoIP traffic. This allows the Prestige to work with any type of NAT router and
eliminates the need for STUN or a SIP ALG. Turn off a SIP ALG on a NAT router in front of
the Prestige to keep it from retranslating the IP address (since this is already handled by the
outbound proxy server).

5.5 Pulse Code Modulation

Pulse Code Modulation (PCM) measures analog signal amplitudes at regular time intervals
and converts them into bits.

5.6 Voice Coding

A codec (coder/decoder) codes analog voice signals into digital signals and decodes the digital
signals back into voice signals. The Prestige supports the following codecs.

54 Chapter 5 Introduction to VoIP

5.6.1 G.711

G.711 is a Pulse Code Modulation (PCM) waveform codec. G.711 provides very good sound
quality but requires 64kbps of bandwidth.

5.6.2 G.729

G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec that uses a filter based on
information about how the human vocal tract produces sounds. G.729 provides good sound
quality and reduces the required bandwidth to 8kbps.

5.7 PSTN Call Setup Signaling

Dual-Tone MultiFrequency (DTMF) signaling uses pairs of frequencies (one lower frequency
and one higher frequency) to set up calls. It is also known as Touch Tone®. Each of the keys
on a DTMF telephone corresponds to a different pair of frequencies.

Pulse dialing sends a series of clicks to the local phone office in order to dial numbers.

P-2002 Series User’s Guide

1

5.8 MWI (Message Waiting Indication)

Enable Message Waiting Indication (MWI) enables your phone to give you a message–
waiting (beeping) dial tone when you have a voice message(s). Your voice service provider
must have a messaging system that sends message waiting status SIP packets as defined in
RFC 3842.

• You can record up to ten different custom tones for a total time of 120 seconds.

• An individual tone can last up to 20 seconds.

• For example you could record up to ten 12-second tones or up to six 20-second tones.

• The same recordings apply to both the caller ringing and on hold tones. This means that

6.5 Quality of Service (QoS)

Quality of Service (QoS) refers to both a network's ability to deliver data with minimum delay,
and the networking methods used to provide bandwidth for real-time multimedia applications.

6.5.1 Type Of Service (ToS)

Network traffic can be classified by setting the ToS (Type Of Service) values at the data
source (for example, at the Prestige) so a server can decide the best method of delivery, that is
the least cost, fastest route and so on.

6.5.2 DiffServ

DiffServ is a class of service (CoS) model that marks packets so that they receive specific per­hop treatment at DiffServ-compliant network devices along the route based on the application
types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the
level of service desired. This allows the intermediary DiffServ-compliant network devices to
handle the packets differently depending on the code points without the need to negotiate
paths or remember state information for every flow. In addition, applications do not have to
request a particular service or give advanced notice of where the traffic is going.

1. The Prestige does not support DiffServ at the time of writing.

64 Chapter 6 VoIP Screens

6.5.2.1 DSCP and Per-Hop Behavior

DiffServ defines a new DS (Differentiated Services) field to replace the Type of Service
(TOS) field in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field
which can define up to 64 service levels. The following figure illustrates the DS field.

DSCP is backward compatible with the three precedence bits in the ToS octet so that non­DiffServ compliant, ToS-enabled network device will not conflict with the DSCP mapping.

Figure 26 DiffServ: Differentiated Service Field

P-2002 Series User’s Guide

DSCP
(6-bit)

Unused

(2-bit)

The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each
packet gets across the DiffServ network. Based on the marking rule, different kinds of traffic
can be marked for different priorities of forwarding. Resources can then be allocated
according to the DSCP values and the configured policies.

6.5.3 VLAN

Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple
logical networks. Only stations within the same group can communicate with each other.

Your Prestige can add IEEE 802.1Q VLAN ID tags to voice frames that it sends to the
network. This allows the Prestige to communicate with a SIP server that is a member of the
same VLAN group. Some ISPs use the VLAN tag to identify voice traffic and give it priority
over other traffic.

CHAPTER 7

This chapter covers how to adjust the Prestige’s phone settings.

7.1 Phone Introduction

You can configure the volume, echo cancellation and VAD settings for each individual phone
port on the Prestige. You can also select which SIP account to use for making outgoing calls.

7.1.1 Voice Activity Detection/Silence Suppression

Voice Activity Detection (VAD) detects whether or not speech is present. This lets the
Prestige reduce the bandwidth that a call uses by not transmitting “silent packets” when you
are not speaking.

P-2002 Series User’s Guide

Phone

7.1.2 Comfort Noise Generation

When using VAD, the Prestige generates and sends comfort noise when the other party is not
speaking. Comfort noise uses the lowest possible transmission bandwidth to match the
background noise. The comfort noise lets you know that the line is still connected as total
silence could easily be mistaken for a lost connection.

7.1.3 Echo Cancellation

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

7.2 Phone Port Configuration

Click PHONE in the navigation panel to display the following screen. Use this screen to

from your voice service provider. The Prestige supports the following services:

• Call Hold

• Call Waiting

• Making a Second Call

• Call Transfer

• Call Forwarding (see Section 8.3 on page 77)

• Three-Way Conference

P-2002 Series User’s Guide

7.3.1 The Flash Key

Flashing means to press the hook for a short period of time (a few hundred milliseconds)
before releasing it. On newer telephones, there should be a "flash" key (button) that generates
the signal electronically. If the flash key is not available, you can tap (press and immediately
release) the hook by hand to achieve the same effect. However, using the flash key is preferred
since the timing is much more precise. With manual tapping, if the duration is too long, it may
be interpreted as hanging up by the Prestige.

You can invoke all the supplementary services by using the flash key.

7.3.2 Europe Type Supplementary Phone Services

This section describes how to use supplementary phone services with the Europe Type Call
Service Mode. Commands for supplementary services are listed in the table below.

8.1 Phone Book Introduction

You can use the phone book feature to configure speed dial entries, call forwarding tables and
the lifeline settings.

Speed dial provides shortcuts for dialing frequently used (VoIP) phone numbers.

8.1.1.1 Peer-to-Peer Calls

P-2002 Series User’s Guide

CHAPTER 8

Phone Book

You can call another VoIP device directly without going through a SIP server. You must set
up a speed dial entry in the phone book in order to do this. Select Non-Proxy (Use IP or
URL) in the Type column and enter the callee’s IP address or domain name. The Prestige
sends SIP INVITE requests to the peer VoIP device when you use the speed dial entry.

You do not need to configure a SIP account on the Prestige 2002 in order to make a peer-to­peer VoIP call. You must still configure a SIP account on the Prestige 2002L in order to make
a peer-to-peer VoIP call.

8.1.2 Lifeline (Prestige 2002L)

With lifeline you can make and receive regular phone calls. Use a prefix number to make a
regular call. When the Prestige 2002L does not have power, you can make regular calls
without dialing a prefix number.

You can also specify phone numbers that should always use the regular phone service (without
having to dial a prefix number). Do this for emergency numbers (like those for contacting
police, fire or emergency medical services).

The Prestige cannot
get an IP address
from the ISP.

If the LAN or PC LED is off, see Table 34 on page 95.
Make sure that the IP address and the subnet mask of the Prestige and your

computer(s) are on the same subnet.

If the LAN and PC LEDs are both off, see Table 34 on page 95.
Make sure that the IP address and the subnet mask of the Prestige and the

computers are on the same subnet.

The ISP provides the IP address after authenticating you. Authentication may be
through the user name and password, the MAC address or the host name.

The username and password apply to PPPoE and PPPoA encapsulation only.
Make sure that you have entered the correct Service Type, User Name and
Password (be sure to use the correct casing). Verify your Ethernet settings, see

PROBLEM CORRECTIVE ACTION

P-2002 Series User’s Guide

I cannot access the
web configurator.

I access the wrong
Prestige when
using the
management IP
address for access.

If the Prestige’s Ethernet IP address or management IP address has changed,
then enter the new one as the URL.

Your computer’s IP address must be on the same subnet as the Prestige’s
Ethernet IP address or management IP address (whichever you use to access the
Prestige).

See Section 12.9 on page 99 to check that pop-up windows, JavaScripts and
Java permissions are allowed.

Ping the Prestige. In the computer, click Start, (All) Programs, Accessories and
then Command Prompt. In the Command Prompt window, type "ping" followed
by the Prestige’s IP address (192.168.5.1 is the default management IP address)
and then press [ENTER]. The Prestige should reply. Otherwise, make sure your
computer’s Ethernet adapter is installed and functioning properly.

You may also need to clear your Internet browser’s cache.
In Internet Explorer, click To ols and then Internet Options to open the Internet

Options screen.
In the General tab, click Delete Files. In the pop-up window, select the Delete all

offline content check box and click OK. Click OK in the Internet Options screen
to close it.

If you disconnect your computer from one device and connect it to another device
that has the same IP address, your computer’s ARP (Address Resolution
Protocol) table may contain an entry that maps the management IP address to
the previous device’s MAC address).

In Windows, use arp -d at the command prompt to delete all entries in your
computer’s ARP table.

This problem may occur if you have more than one Prestige on the same LAN.
Disconnect your Prestige from the network and connect directly through the
Prestige’s PC port. You may also need to delete your computer’s ARP table entry
for the Prestige’s IP address (see above).

PROBLEM CORRECTIVE ACTION

There is no dial
tone or I can’t make
or receive calls.

or
There is beeping

instead of the dial
tone.

There is a beep
before the dial tone.

Check the telephone connections and telephone wire.
Beeping means that there is not a SIP account registered for the phone to use.
You can check the Prestige’s IP addresses and VoIP status in the Maintenance

Status screen.
Make sure you have the VoIP screen properly configured. If you configured a SIP

account to receive calls on only one of the phone ports, make sure your phone is
connected to that port.

Make sure you have the Phone Port screen properly configured. If you
configured a phone port to only use one of the SIP accounts for outgoing calls,
make sure that SIP account is properly configured and active (see the VoI P and
Maintenance Status screens).

A single beep before the dial tone indicates that there is a voice message for SIP
account 1.

Two beeps before the dial tone indicate that there is a voice message for SIP
account 2.

Use your voice service provider’s instructions to check your voice messages.

12.8 Problems with Voice Service

Table 40 Troubleshooting Voice Service

PROBLEM CORRECTIVE ACTION

After the VoIP is
configured and
working, others are
unable to call you
or you lose your
connection during a
call. There is a NAT
router between the
Prestige and the
SIP server.

This could be caused by a short NAT UDP session timeout on the NAT router.
When the SIP session’s entry in the NAT table times out, the NAT router does not
have any record to use for forwarding VoIP traffic to the Prestige.

If possible, set the NAT router to use a longer NAT UDP session timeout.
Otherwise, try one of the following:

• Shorten the registration expiration period (see the Expiration Duration field
in the VoIP Advanced screen) in order to cause the Prestige to re-register
with the SIP register server more frequently. Note that this will not help if the
SIP register server enforces a long registration expiration period (since the
Prestige will also use the period set by the SIP register server).

• Use STUN. If your VoIP service provider does not have a STUN server, you
can still enable STUN and enter the IP address and port number of the SIP
server in the STUN server fields. This causes the Prestige to send STUN
requests to the SIP server. While this will not make STUN work (since there
won’t be any responses to the STUN requests), it should keep the NAT UDP
session in the NAT router.
