Introduction

About This Guide

Yealink administrator guide is intended for administrators who need to properly configure,

customize, manage, and troubleshoot the IP phone system rather than end-users. This guide will

help you understand the Voice over Internet Protocol (VoIP) network and Session Initiation

Protocol (SIP) components, and provides descriptions of all available phone features.

This guide describes three methods for configuring IP phones: central provisioning, web user

interface and phone user interface. It will help you perform the following tasks:

Configure your IP phone on a provisioning server

Configure your phone’s features and functions via web/phone user interface

Troubleshoot some common phone issues

Many of the features described in this guide involve network settings, which could affect the IP

phone’s performance in the network. So an understanding of IP networking and a prior

knowledge of IP telephony concepts are necessary.

The information detailed in this guide is applicable to firmware version 81 or higher. The

firmware format is like x.x.x.x.rom. The second x from left must be greater than or equal to 81

(e.g., the firmware version of SIP-T46G IP phone: 28.81.0.70.rom).

You need to know the following basic typographic conventions to distinguish types of in-text

information:

Convention

Description

Bold

Highlights the web/phone user interface items such as menus,

menu selections, soft keys, or directory names when they are

involved in a procedure or user action (e.g., Click on

Settings->Upgrade.).

Also used to emphasize text (e.g., Important!).

Italics

Used to show the format of examples (e.g.,

http(s)://[IPv6

address]

), or to show the title of a section in the reference

documentations available on the Yealink Technical Support

Website (e.g.,

Triggering the IP phone to Perform the Auto

Provisioning

Blue Text

Used for cross references to other sections within this

documentation (e.g., refer to Ring Tones on page 771), for

hyperlinks to non-Yealink websites (e.g., RFC 3315) or for

hyperlinks to Yealink Technical Support website.

Blue Text in Italics

Used for hyperlinks to Yealink resources outside of this

documentation such as the Yealink documentations (e.g.,

Yealink_SIP-T2_Series_T19(P)

E2_T4_Series_T5_Series_W5_Series_IP_Phones_Auto_Provisioning_

Guide_V81

You also need to know the following writing conventions to distinguish conditional information:

Convention

Description

Indicates that you must enter information specific to phone or

network. For example, when you see <MAC>, enter your phone’s

12-digit MAC address. If you see <phoneIPAddress>, enter your

phone’s IP address.

Indicates that you need to select an item from a menu. For

example, Settings->Basic Settings indicates that you need to

select Basic Settings from the Settings menu.

Reading the Configuration Parameter Tables

The feature descriptions discussed in this guide include two tables. One is a summary table of

provisioning methods that you can use to configure the features. The other is a table of details

Administrator’s Guide for SIP-T2 Series/T19(P) E2/T4 Series IP Phones

viii

of the configuration parameters that you configure to make the features work.

This brief section describes the conventions used in the summary table and configuration

parameter table. In order to read the tables and successfully perform configuration changes, an

understanding of these conventions is necessary.

The following summary table indicates three provisioning methods (central provisioning, web

user interface and phone user interface, refer to Provisioning Methods for more information)

you can use to configure a feature. Note that the types of provisioning methods available for

each feature will vary; not every feature uses all these three methods.

The central provisioning method requires you to configure parameters located in CFG format

configuration files that Yealink provides. For more information on configuration files, refer to

Configuration Files on page 127. As shown below, the table specifies the configuration file name

and the corresponding parameters. That is, the <MAC>.cfg file contains the

account.X.auto_answer

parameter, and the <y0000000000xx>.cfg file contains the

feature.auto_answer_delay

parameter.

The web user interface method requires you to configure features by navigating to the specified

link. This navigation URL can help you quickly locate the webpage where you can configure the

feature.

Introduction

The following configuration parameter table describes the parameter that you can configure to

make the feature (e.g., auto answer) work.

Note

The above table also indicates three methods for configuring the feature.

Method 1: Central Provisioning

This table specifies the details of

account.X.auto_answer

parameter, which enables or disables

the auto answer feature. This parameter is disabled by default. If you want to enable the auto

answer feature, open the MAC.cfg file and locate the parameter name

account.X.auto_answer

Set the parameter value to “1” to enable the auto answer feature or “0” to disable the auto

answer feature.

Note that some parameters described in this guide contain one or more variables (e.g., X or Y).

But the variables in the parameters described in the CFG file are all replaced with specific value

in the scope of variable. You may need to assign a value to the variable before you search and

locate the specific parameter in the CFG file.

Sometimes you will see the words “Refer to the following content” in the Permitted Values or

Default field. It means the permitted value or the default value of the parameter has the model

difference or there are many permitted values of the parameter, you can get more details from

the following Description field.

The word “None”in the Web User Interface or Phone User Interface field means this feature

cannot be configured via web/phone user interface.

Administrator’s Guide for SIP-T2 Series/T19(P) E2/T4 Series IP Phones

For example, if you want to enable the auto answer feature for account 1, you need to locate the

account.1.auto_answer

in the MAC.cfg file and then configure it as required (e.g.,

account.1.auto_answer = 1). If you want to configure the SIP server 1 for account 1, you can

locate the

account.1.sip_server.1.address

in the MAC.cfg file and configure it as required (e.g.,

account.1.sip_server.1.address = 10.2.1.48).

The following shows a segment of MAC.cfg file:

Method 2: Web User Interface

As described in the chapter Summary Table Format, you can directly navigate to the specified

webpage to configure the feature. You can also first log into the web user interface, and then

locate the feature field according to the web path (e.g., Account->Basic->Auto Answer) to

configure it as required.

Introduction

As shown in the following illustration:

To successfully log into the web user interface, you may need to enter the user name (default:

admin) and password (default: admin). For more information, refer to Web User Interface on

page 124.

Method 3: Phone User Interface

You can configure features via phone user interface. Access to the desired feature according to

the phone path (e.g., Menu->Features->Auto Answer->Line X->Auto Answer) and then

configure it as required.

As shown in the following illustration:

Understanding VoIP Principle and SIP Components

This section mainly describes the basic knowledge of VoIP principle and SIP components, which

will help you have a better understanding of the phone’s deployment scenarios.

VoIP

VoIP (Voice over Internet Protocol) is a technology using the Internet Protocol instead of

traditional Public Switch Telephone Network (PSTN) technology for voice communications.

It is a family of technologies, methodologies, communication protocols, and transmission

techniques for the delivery of voice communications and multimedia sessions over IP networks.

The H.323 and Session Initiation Protocol (SIP) are two popular VoIP protocols that are found in

widespread implementation.

H.323

H.323 is a recommendation from the ITU Telecommunication Standardization Sector (ITU-T)

that defines the protocols to provide audio-visual communication sessions on any packet

network. The H.323 standard addresses call signaling and control, multimedia transport and

control, and bandwidth control for point-to-point and multi-point conferences.

It is widely implemented by voice and video conference equipment manufacturers, is used

within various Internet real-time applications such as GnuGK and NetMeeting and is widely

deployed by service providers and enterprises for both voice and video services over IP

networks.

SIP

SIP (Session Initiation Protocol) is the Internet Engineering Task Force’s (IETF’s) standard for

multimedia conferencing over IP. It is an ASCII-based, application-layer control protocol

(defined in RFC 3261) that can be used to establish, maintain, and terminate calls between two

or more endpoints. Like other VoIP protocols, SIP is designed to address functions of signaling

and session management within a packet telephony network. Signaling allows call information

to be carried across network boundaries. Session management provides the ability to control

attributes of an end-to-end call.

Introduction

xiii

SIP provides capabilities to:

Determine the location of the target endpoint -- SIP supports address resolution, name

mapping, and call redirection.

Determine media capabilities of the target endpoint -- Via Session Description Protocol

(SDP), SIP determines the “lowest level” of common services between endpoints.

Conferences are established using only media capabilities that can be supported by all

endpoints.

Determine the availability of the target endpoint -- A call cannot be completed because

the target endpoint is unavailable, SIP determines whether the called party is already on

the IP phone or does not answer in the allotted number of rings. It then returns a message

indicating why the target endpoint is unavailable.

Establish a session between the origin and target endpoint -- The call can be completed,

SIP establishes a session between endpoints. SIP also supports mid-call changes, such as

the addition of another endpoint to the conference or the change of a media characteristic

or codec.

Handle the transfer and termination of calls -- SIP supports the transfer of calls from one

endpoint to another. During a call transfer, SIP simply establishes a session between the

transferee and a new endpoint (specified by the transferring party) and terminates the

session between the transferee and the transferring party. At the end of a call, SIP

terminates the sessions between all parties.

SIP is a peer-to-peer protocol. The peers in a session are called User Agents (UAs). A user agent

can function as one of following roles:

User Agent Client (UAC) -- A client application that initiates the SIP request.

User Agent Server (UAS) -- A server application that contacts the user when a SIP request is

received and that returns a response on behalf of the user.

User Agent Client (UAC)

The UAC is an application that initiates up to six feasible SIP requests to the UAS. The six

requests issued by the UAC are: INVITE, ACK, OPTIONS, BYE, CANCEL and REGISTER. When the

SIP session is being initiated by the UAC SIP component, the UAC determines the information

essential for the request, which is the protocol, the port and the IP address of the UAS to which

the request is being sent. This information can be dynamic and will make it challenging to put

through a firewall. For this reason, it may be recommended to open the specific application type

on the firewall. The UAC is also capable of using the information in the request URI to establish

the course of the SIP request to its destination, as the request URI always specifies the host

which is essential. The port and protocol are not always specified by the request URI. Thus if the

request does not specify a port or protocol, a default port or protocol is contacted. It may be

preferential to use this method when not using an application layer firewall. Application layer

Administrator’s Guide for SIP-T2 Series/T19(P) E2/T4 Series IP Phones

xiv

firewalls like to know what applications are flowing through which ports and it is possible to use

content types of other applications other than the one you are trying to let through what has

been denied.

User Agent Server (UAS)

UAS is a server that hosts the application responsible for receiving the SIP requests from a UAC,

and on reception it returns a response to the request back to the UAC. The UAS may issue

multiple responses to the UAC, not necessarily a single response. Communication between UAC

and UAS is client/server and peer-to–peer.

Typically, a SIP endpoint is capable of functioning as both a UAC and a UAS, but it functions only

as one or the other per transaction. Whether the endpoint functions as a UAC or a UAS depends

on the UA that initiates the request.
