documentation (e.g., refer to Call Waiting on page 214), 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 DECT IP Phones Description of Configuration Parameters

in CFG Files_V81.xlsx

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

information:

Convention

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->System Settings indicates that you need to

select System 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 W60P DECT 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.

Summary Table Format

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

user interface and handset 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 86. As shown below, the table specifies the configuration file name

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

account.X

.dnd.enable,

account.X.dnd.on_code

and

account.X.dnd.off_code

parameters, and the

y000000000077.cfg file contains the

feature.dnd_refuse_code

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.

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

Method 1: Central Provisioning

This table specifies the details of

account.X.dnd.enable

parameter, which enables or disables

the DND feature. This parameter is disabled by default. If you want to enable the DND feature,

open the MAC.cfg file and locate the parameter name

account.X.dnd.enable

. Set the parameter

value to “1” to enable the DND feature or “0” to disable the DND feature.

Introduction

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.

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

account.1.dnd.enable

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

account.1

.dnd.enable = 1).

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, the default

user name and password for the administrator are both “admin”(case-sensitive). Yealink DECT

IP phones support both HTTP and HTTPS protocols for accessing the web user interface. For

more information, refer to Web User Interface on page 83.

Administrator’s Guide for W60P DECT IP Phones

The following web user interface takes Features->Forward&DND as an example:

Method 3: Handset User Interface

An administrator or a user can configure and use DECT IP phones via handset user interface.

Not all features are available on handset user interface. You can only access some features

when the handset disconnects with the base station.

Understanding VoIP Principle and SIP Components

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

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

Introduction

VoIP Principle

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.

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 DECT 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,

Administrator’s Guide for W60P DECT IP Phones

xii

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 Components

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 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.
