10.1 Overview
Use this chapter to:
• Connect an analog phone to the ZyXEL Device.
• Make phone calls over the Internet, as well as the regular phone network.
• Configure settings such as speed dial and distinctive ringing.
• Configure network settings to optimize the voice quality of your phone calls.
10.1.1 What You Can Do in the VoIP Screens
These screens allow you to configure your ZyXEL Device to make phone calls over the Internet and your regular phone line, and to set up the phones you connect to the ZyXEL Device.
• Use the SIP Settings screen (
) to set up information about your SIP account.
• Use the SIP QoS screen (
Section 10.4 on page 193 ) to configure Quality of
Service for VoIP calls. QoS can give VoIP traffic higher priority on the network so it gets dealt with more quickly.
• Use the Analog Phone screen ( Section 10.5 on page 194
) to control which SIP accounts the phones connected to the ZyXEL Device use.
• Use the Advanced Analog Phone Setup screen (
configure audio settings such as volume levels for the phones connected to the
ZyXEL Device.
• Use the EXT. Table screen (
Section 10.7 on page 197 ) to configure extension
numbers for the phones connected to the ZyXEL Device so they can be separately identified for intercom use.
• Use the Common Phone Settings screen ( Section 10.8 on page 198
) to turn immediate dialing on or off.
• Use the Region screen (
Section 10.9 on page 199 ) to change settings that
depend on the country you are in.
• Use the Speed Dial screen (
Section 10.10 on page 200 ) to set up shortcuts for
dialing frequently-used (VoIP) phone numbers.

Chapter 10 Voice
• Use the Incoming Call Policy screen (
Section 10.11 on page 203 ) to configure
how the ZyXEL Device deals with incoming calls.
• Use the SIP Prefix screen (
Section 10.12 on page 205 ) to set up numbers you
dial on your phone that specify which SIP account you want to use.
You don’t necessarily need to use all these screens to set up your account. In fact, if your service provider did not supply information on a particular field in a screen, it is usually best to leave it at its default setting.
10.1.2 What You Need to Know About VoIP
VoIP
VoIP stands for Voice over IP. IP is the Internet Protocol, which is the messagecarrying standard the Internet runs on. So, Voice over IP is the sending of voice signals (speech) over the Internet (or another network that uses the Internet
Protocol).
SIP
SIP stands for Session Initiation Protocol. SIP is a signalling standard that lets one network device (like a computer or the ZyXEL Device) send messages to another.
In VoIP, these messages are about phone calls over the network. For example, when you dial a number on your ZyXEL Device, it sends a SIP message over the network asking the other device (the number you dialed) to take part in the call.
SIP Accounts
A SIP account is a type of VoIP account. It is an arrangement with a service provider that lets you make phone calls over the Internet. When you set the
ZyXEL Device to use your SIP account to make calls, the ZyXEL Device is able to send all the information about the phone call to your service provider on the
Internet.
Strictly speaking, you don’t need a SIP account. It is possible for one SIP device
(like the ZyXEL Device) to call another without involving a SIP service provider.
However, the networking difficulties involved in doing this make it tremendously impractical under normal circumstances. Your SIP account provider removes these difficulties by taking care of the call routing and setup - figuring out how to get your call to the right place in a way that you and the other person can talk to one another.

Chapter 10 Voice
for advanced technical information on SIP.
10.1.3 Before You Begin
• Before you can use these screens, you need to have a VoIP account already set up. If you don’t have one yet, you can sign up with a VoIP service provider over the Internet.
• You should have the information your VoIP service provider gave you ready, before you start to configure the ZyXEL Device.
10.2 The SIP Settings Screen
The ZyXEL Device uses a SIP account to make outgoing VoIP calls and check if an incoming call’s destination number matches your SIP account’s SIP number. In order to make or receive a VoIP call, you need to enable and configure a SIP account, and map it to a phone port. The SIP account contains information that allows your ZyXEL Device to connect to your VoIP service provider.
If you want to make only peer-to-peer VoIP calls, there is no VoIP service provider involved, so the SIP account information does not have to match a real VoIP service provider’s SIP account. You can make up the SIP numbers. However, you should still activate a SIP account and configure its number and map it to a phone port, so that the person you call knows what SIP number you are using and the
ZyXEL Device knows to which phone port it should forward an incoming VoIP call.
You must use speed dial to make peer-to-peer VoIP calls.
See
for how to map a SIP account to a phone port.

Voice Activity Detection/Silence Suppression
Voice Activity Detection (VAD) detects whether or not speech is present. This lets the ZyXEL Device reduce the bandwidth that a call uses by not transmitting “silent packets” when you are not speaking.
Comfort Noise Generation
When using VAD, the ZyXEL Device generates comfort noise when the other party is not speaking. The comfort noise lets you know that the line is still connected as total silence could easily be mistaken for a lost connection.
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.

10.13 SIP Technical Reference
This section contains background material relevant to the VoIP > SIP screens.
10.13.1 VoIP
VoIP is the sending of voice signals over 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.
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.
10.13.2 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
206
P-2612HW Series User’s Guide
Chapter 10 Voice signaling. SIP handles telephone calls and can interface with traditional circuitswitched telephone networks.
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.
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 ([email protected] for example) or numbers like a telephone number ([email protected] for example).
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 [email protected]
, then
“VoIP-provider.com” is the SIP service domain.
SIP Registration
Each ZyXEL Device is an individual SIP User Agent (UA). To provide voice service, it has a public IP address for SIP and RTP protocols to communicate with other servers.
A SIP user agent has to register with the SIP registrar and must provide information about the users it represents, as well as its current IP address (for the routing of incoming SIP requests). After successful registration, the SIP server knows that the users (identified by their dedicated SIP URIs) are represented by the UA, and knows the IP address to which the SIP requests and responses should be sent.
Registration is initiated by the User Agent Client (UAC) running in the VoIP gateway (the ZyXEL Device). The gateway must be configured with information letting it know where to send the REGISTER message, as well as the relevant user and authorization data.
A SIP registration has a limited lifespan. The User Agent Client must renew its registration within this lifespan. If it does not do so, the registration data will be deleted from the SIP registrar's database and the connection broken.
P-2612HW Series User’s Guide
207
Chapter 10 Voice
The ZyXEL Device attempts to register all enabled subscriber ports when it is switched on. When you enable a subscriber port that was previously disabled, the
ZyXEL Device attempts to register the port immediately.
Authorization Requirements
SIP registrations (and subsequent SIP requests) require a username and password for authorization. These credentials are validated via a challenge / response system using the HTTP digest mechanism (as detailed in RFC3261, "SIP:
Session Initiation Protocol").
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.
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 130 SIP User Agent
208
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).
P-2612HW Series User’s Guide
2
The SIP proxy server forwards the call invitation to C.
Figure 131 SIP Proxy Server
Chapter 10 Voice
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).
P-2612HW Series User’s Guide
209
Chapter 10 Voice
3
Client device A then sends the call invitation to client device C.
Figure 132 SIP Redirect Server
210
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.
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.
Pulse Code Modulation
Pulse Code Modulation (PCM) measures analog signal amplitudes at regular time intervals and converts them into bits.
SIP Call Progression
The following figure displays the basic steps in the setup and tear down of a SIP call. A calls B.

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.
SIP Call Progression Through Proxy Servers
Usually, the SIP UAC sets up a phone call by sending a request to the SIP proxy server. Then, the proxy server looks up the destination to which the call should be forwarded (according to the URI requested by the SIP UAC). The request may be forwarded to more than one proxy server before arriving at its destination.
The response to the request goes to all the proxy servers through which the request passed, in reverse sequence. Once the session is set up, session traffic is sent between the UAs directly, bypassing all the proxy servers in between.

User Agent 2 sends a response back to Proxy 2 indicating that the phone is ringing. The response is relayed back to User Agent 1 via Proxy 1.
5
User Agent 2 sends an OK response to Proxy 2 after the call is answered. This is also relayed back to User Agent 1 via Proxy 1.
6
User Agent 1 and User Agent 2 exchange RTP packets containing voice data directly, without involving the proxies.
7
When User Agent 2 hangs up, he sends a BYE request.
8
User Agent 1 replies with an OK response confirming receipt of the BYE request, and the call is terminated.
Voice Coding
A codec (coder/decoder) codes analog voice signals into digital signals and decodes the digital signals back into analog voice signals. The ZyXEL Device supports the following codecs.
• G.711 is a Pulse Code Modulation (PCM) waveform codec. PCM measures analog signal amplitudes at regular time intervals and converts them into digital samples. G.711 provides very good sound quality but requires 64 kbps of bandwidth.
• G.726 is an Adaptive Differential PCM (ADPCM) waveform codec that uses a lower bitrate than standard PCM conversion. ADPCM converts analog audio into digital signals based on the difference between each audio sample and a prediction based on previous samples. The more similar the audio sample is to the prediction, the less space needed to describe it. G.726 operates at 16, 24,
32 or 40 kbps.
• 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 8 kbps.
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.
P-2612HW Series User’s Guide
213
Chapter 10 Voice
Pulse dialing sends a series of clicks to the local phone office in order to dial numbers.

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
VoIP service provider must have a messaging system that sends message waiting status SIP packets as defined in RFC 3842.
Custom Tones (IVR)
IVR (Interactive Voice Response) is a feature that allows you to use your telephone to interact with the ZyXEL Device. The ZyXEL Device allows you to record custom tones for the Caller Ringing Tone and On Hold Tone functions.
The same recordings apply to both the caller ringing and on hold tones.

10.13.3 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 realtime multimedia applications.
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 ZyXEL Device) so a server can decide the best method of delivery, that is the least cost, fastest route and so on.
DiffServ
DiffServ is a class of service (CoS) model that marks packets so that they receive specific per-hop treatment at DiffServ-compliant network devices along the route based on the application types and traffic flow. Packets are marked with DiffServ
Code Points (DSCP) 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.
4
4.
The ZyXEL Device does not support DiffServ at the time of writing.
P-2612HW Series User’s Guide
215
Chapter 10 Voice
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 non-DiffServ compliant, ToS-enabled network device will not conflict with the
DSCP mapping.
Figure 134 DiffServ: Differentiated Service Field
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.
VLAN Tagging
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 ZyXEL Device can add IEEE 802.1Q VLAN ID tags to voice frames that it sends to the network. This allows the ZyXEL Device 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.
10.13.4 Phone Services Overview
Supplementary services such as call hold, call waiting, and call transfer. are generally available from your VoIP service provider. The ZyXEL Device supports the following services:
• Call Hold
• Call Waiting
• Making a Second Call
• Call Transfer
• Call Forwarding (see
216
P-2612HW Series User’s Guide
Chapter 10 Voice
• Three-Way Conference
• Internal Calls
• Call Park and Pickup
• Do not Disturb
Note: To take full advantage of the supplementary phone services available through the ZyXEL Device's phone ports, you may need to subscribe to the services from your VoIP service provider.
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 ZyXEL Device.
You can invoke all the supplementary services by using the flash key.
