Introduction

About This Guide

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

customize, manage, and troubleshoot the smart media phones rather than end-users. This guide

will help you understand the VoIP network and 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

Introduction



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 80 or higher. The

firmware format is like x.x.x.x.rom. The second x from left must be greater than or equal to 80

(e.g., the firmware version of SIP-T58V IP phone: 58.80.0.5.rom).

Reading the Configuration Parameter Tables

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

vii

Administrator’s Guide for SIP-T5 Series Smart Media Phones

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

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 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 116. As shown below, the table specifies the configuration file name

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

parameter, and the y0000000000xx.cfg file contains the

account.X.auto_answer

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.

viii

Configuration Parameter Table Format

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

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

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

Introduction

Note

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 configurable via web/phone user interface.

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

Method 1: Central Provisioning

This table specifies the details of

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

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.

account.X.auto_answer

parameter, which enables or disables

account.X.auto_answer

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

account.1.auto_answer

account.1.auto_answer = 1). If you want to enable the audio codec 1 for account 1, you can

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

Administrator’s Guide for SIP-T5 Series Smart Media Phones

locate the

account.1.codec.1.enable = 1).

The following shows a segment of MAC.cfg file:

account.1.codec.1.enable

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

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.

As shown in the following illustration:

Introduction

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 113.

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., Settings->Features->Auto Answer->Account X) 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.

Administrator’s Guide for SIP-T5 Series Smart Media Phones

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.

xii

 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 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.

Introduction

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.

Getting Started

What IP Phones Need to Meet

In order to operate as SIP endpoints in your network successfully, IP phones must meet the

following requirements:

 A working IP network is established.

 VoIP gateways are configured for SIP.

 The latest (or compatible) firmware of IP phones is available.

 A call server is active and configured to receive and send SIP messages.

Yealink IP Phones in a Network

Yealink IP phones can connect physically through a Category 5E (CAT 5E) cable to a Ethernet

LAN, and send and receive all data using the same packet-based technology. They can also

connect to the wireless network.

Since the IP phone is a data terminal, digitized audio being just another type of data from its

perspective, the phone is capable of vastly more than traditional business phones. Moreover,

Yealink IP phones run the same protocols as your office personal computer, which means that

many innovative applications can be developed without resorting to specialized technology.

Initialization Process Overview

The initialization process of the IP phone is responsible for network connectivity and operation

of the IP phone in your local network.

Once you connect your IP phone to the network and to an electrical supply, the IP phone begins

its initialization process.

During the initialization process, the following events take place:

Loading the ROM file

The ROM file resides in the flash memory of the IP phone. The IP phone comes from the factory

with a ROM file preloaded. During initialization, the IP phone runs a bootstrap loader that loads

and executes the ROM file.

Configuring the VLAN

If the IP phone is connected to a switch, the switch notifies the IP phone of the VLAN

information defined on the switch (if using LLDP or CDP). The IP phone can then proceed with

the DHCP request for its network settings (if using DHCP). For more information on VLAN, refer

to VLAN on page 53.

Querying the DHCP (Dynamic Host Configuration Protocol) Server

The IP phone is capable of querying a DHCP server. DHCP is enabled on the IP phone by default.

The following network parameters can be obtained from the DHCP server during initialization:

 IP Address

Getting Started

 Subnet Mask

 Gateway

 Primary DNS (Domain Name Server)

 Secondary DNS

You need to configure network parameters of the IP phone manually if any of them is not

supplied by the DHCP server. For more information on configuring network parameters

manually, refer to Configuring Network Parameters Manually on page 32.

Contacting the provisioning server

If the IP phone is configured to obtain configurations from the provisioning server, it will

connect to the provisioning server and download the configuration file(s) during startup. The IP

phone will be able to resolve and update configurations written in the configuration file(s). If the

IP phone does not obtain configurations from the provisioning server, the IP phone will use

configurations stored in the flash memory. For more information, refer to Setting Up Your

Phones with a Provisioning Server on page 110.

Updating firmware

If the access URL of firmware is defined in the configuration file, the IP phone will download

firmware from the provisioning server. If the MD5 value of the downloaded firmware file differs

from that of the image stored in the flash memory, the IP phone will perform a firmware update.

You can manually upgrade firmware if the IP phone does not download firmware from the

provisioning server. For more information, refer to Upgrading Firmware on page 124.

Downloading the resource files

In addition to configuration file(s), the IP phone may require resource files before it can deliver

service. These resource files are optional, but if some particular features are being deployed,

these files are required.

The followings show examples of resource files:

 Language packs

 Ring tones

 Contact files

For more information on resource files, refer to Resource Files on page 118.

Verifying Startup

After connected to the power and network, the IP phone begins the initializing process by

cycling through the following steps:

1. The power indicator LED/mute indicator LED illuminates solid red.

2. The message “Welcome Initializing… Please wait” appears on the touch screen when the IP

phone starts up.

Administrator’s Guide for SIP-T5 Series Smart Media Phones

3. The main touch screen displays the following:

 Time and date

 Android keys (for SIP-T58V/T58A/T56A)

 Pre-installed applications (for CP960)

4. Tap Settings->Status to check the IP phone status, the touch screen displays the valid IP

address, MAC address, firmware version, etc.

If the IP phone has successfully passed through these steps, it starts up properly and is ready for

use.

DHCP

DHCP (Dynamic Host Configuration Protocol) is a network protocol used to dynamically allocate

network parameters to network hosts. The automatic allocation of network parameters to hosts

eases the administrative burden of maintaining an IP network. IP phones comply with the DHCP

specifications documented in RFC 2131. If using DHCP, IP phones connected to the network

become operational without having to be manually assigned IP addresses and additional

network parameters.

Procedure

DHCP can be configured using the following methods.

DHCP Option

DHCP provides a framework for passing information to TCP/IP network devices. Network and

other control information are carried in tagged data items that are stored in the options field of

the DHCP message. The data items themselves are also called options.

DHCP can be initiated by simply connecting the IP phone with the network. IP phones broadcast

DISCOVER messages to request the network information carried in DHCP options, and the

DHCP server responds with specific values in corresponding options.

The following table lists common DHCP options supported by IP phones.

Setting Up Your System

Parameter

DHCP Option

Description

Domain Server

Specify the domain name that client should use

when resolving hostnames via DNS.

Broadcast Address

Specify the broadcast address in use on the

client's subnet.

Network Time Protocol Servers

Specify a list of NTP servers available to the client by IP address.

Vendor-Specific

Information

Identify the vendor-specific information.

TFTP Server Name

Identify a TFTP server when the 'sname' field in

the DHCP header has been used for DHCP

options.

Boot file Name

Identify a boot file when the 'file' field in the

DHCP header has been used for DHCP options.

Central Provisioning

<y0000000000xx>.c

Configure DHCP active.

For more information on DHCP options, refer to RFC 2131 or RFC 2132.

If you do not have the ability to configure the DHCP options for discovering the provisioning

server on the DHCP server, an alternate method of automatically discovering the provisioning

server address is required. Connecting to the secondary DHCP server that responds to DHCP

INFORM queries with a requested provisioning server address is one possibility. For more

information, refer to RFC 3925. If a single alternate DHCP server responds, this is functionally

equivalent to the scenario where the primary DHCP server responds with a valid provisioning

server address. If no DHCP servers respond, the INFORM query process will retry and eventually

time out.

DHCP Option 66 and Option 43

Yealink IP phones support obtaining the provisioning server address by detecting DHCP options

during startup.

The phone will automatically detect the option 66 and option 43 for obtaining the provisioning

server address. DHCP option 66 is used to identify the TFTP server. DHCP option 43 is a

vendor-specific option, which is used to transfer the vendor-specific information.

To use DHCP option 66 or DHCP option 43, make sure the DHCP Active feature is enabled.

Procedure

DHCP active can be configured using the following methods.

Configuring Transmission Methods of the Internet Port and PC

Port

Yealink SIP-T58V/T58A/T56A IP phones support two Ethernet ports: Internet port and PC port.

You can enable or disable the PC port on the IP phones. The CP960 IP phones have Internet port

only. Three optional methods of transmission configuration for IP phone Internet port or PC

port:

 Auto-negotiate

Setting Up Your System

 Half-duplex

 Full-duplex

Auto-negotiate is configured for both Internet and PC ports on the IP phone by default.

Auto-negotiate

Auto-negotiate means that two connected devices choose common transmission parameters

(e.g., speed and duplex mode) to transmit voice or data over Ethernet. This process entails

devices first sharing transmission capabilities and then selecting the highest performance

transmission mode supported by both. You can configure the Internet port and PC port on the

IP phone to automatically negotiate during the transmission.

Half-duplex

Half-duplex transmission refers to transmitting voice or data in both directions, but in one

direction at a time; this means one device can send data on the line, but not receive data

simultaneously. You can configure the half-duplex transmission on both Internet port and PC

port for the IP phone to transmit in 10Mbps or 100Mbps.

this means one device can send data on the line while receiving data. You can configure the

full-duplex transmission on both Internet port and PC port for the IP phone to transmit in

10Mbps, 100Mbps or 1000Mbps (1000Mbps is not applicable to CP960 IP phones).

Web Server Type

Users can configure the user or administrator features of the phone via web user interface. Web

server type determines access protocol of the IP phone’s web user interface. IP phones support

both HTTP and HTTPS protocols for accessing the web user interface through a web browser

such as Microsoft’s IE, Mozilla Firefox, Google Chrome and etc. This can be disabled when it is

not needed or when it poses a security threat. For more information on accessing the web user

interface, refer to Web User Interface on page 113.

HTTP is an application protocol that runs on top of the TCP/IP suite of protocols. HTTPS is a web

protocol that encrypts and decrypts user page requests as well as pages returned by the web

server. Both HTTP and HTTPS port numbers are configurable.

When you enable user to access web user interface of the IP phone using the HTTP/HTTPS

protocol (take HTTPS protocol for example):

VLAN (Virtual Local Area Network) is used to logically divide a physical network into several

broadcast domains. VLAN membership can be configured through software instead of

physically relocating devices or connections. Grouping devices with a common set of

requirements regardless of their physical location can greatly simplify network design. VLANs

can address issues such as scalability, security and network management.

The purpose of VLAN configurations on the IP phone is to insert tag with VLAN information to

the packets generated by the IP phone. When VLAN is properly configured for the ports

(Internet port and PC port) on the IP phone, the IP phone will tag all packets from these ports

with the VLAN ID. The switch receives and forwards the tagged packets to the corresponding

VLAN according to the VLAN ID in the tag as described in IEEE Std 802.3.

VLAN on IP phones allows simultaneous access for a regular PC. This feature allows a PC to be

daisy chained to an IP phone and the connection for both PC and IP phone to be trunked

through the same physical Ethernet cable.

In addition to manual configuration, the IP phone also supports automatic discovery of VLAN

via LLDP, CDP or DHCP. The assignment takes effect in this order: assignment via LLDP/CDP,

manual configuration, then assignment via DHCP.

For more information on VLAN, refer to

LLDP

LLDP (Linker Layer Discovery Protocol) is a vendor-neutral Link Layer protocol, which allows IP

phones to receive and/or transmit device-related information from/to directly connected

devices on the network that are also using the protocol, and store the information about other

devices.

When LLDP feature is enabled on IP phones, the IP phones periodically advertise their own

information to the directly connected LLDP-enabled switch. The IP phones can also receive LLDP

packets from the connected switch. When the application type is “voice”, IP phones decide

whether to update the VLAN configurations obtained from the LLDP packets. When the VLAN

configurations on the IP phones are different from the ones sent by the switch, the IP phones

perform an update and reboot. This allows the IP phones to be plugged into any switch, obtain

their VLAN IDs, and then start communications with the call control.

LLDP can be configured using the following methods.

IPv6 Support

Because Internet Protocol version 4 (IPv4) uses a 32-bit address, it cannot meet the increased

demands for unique IP addresses for all devices that connect to the Internet. Therefore, Internet

Protocol version 6 (IPv6) is the next generation network layer protocol, which designed as a

replacement for the current IPv4 protocol.

IPv6 is developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated

problem of IPv4 address exhaustion. Yealink IP Phone supports IPv4 addressing mode, IPv6

addressing mode, as well as an IPv4&IPv6 dual stack addressing mode. IPv4 uses a 32-bit

address, consisting of four groups of three decimal digits separated by dots; for example,

192.168.1.100. IPv6 uses a 128-bit address, consisting of eight groups of four hexadecimal digits

separated by colons; for example, 2026:1234:1:1:215:65ff:fe1f:caa.

VoIP network based on IPv6 can provide end-to-end security capabilities, enhanced Quality of

Service (QoS), a set of service requirements to deliver performance guarantee while transporting

traffic over the network.

If you configure the network settings on the phone for an IPv6 network, you can set up an IP

address for the phone either by using SLAAC (ICMPv6), DHCPv6 or by manually entering an IP

address. Ensure that your network environment supports IPv6. Contact your ISP for more

information.

IPv6 Address Assignment Method

Supported IPv6 address assignment methods:

 Manual Assignment: An IPv6 address and other configuration parameters (e.g., DNS

server) for the IP phone can be statically configured by an administrator.

 Stateless Address Autoconfiguration (SLAAC)/ ICMPv6: SLAAC is one of the most

convenient methods to assign IP addresses to IPv6 nodes. SLAAC requires no manual

configuration of the IP phone, minimal (if any) configuration of routers, and no additional

servers. To use IPv6 SLAAC, the IP phone must be connected to a network with at least one

IPv6 router connected. This router is configured by the network administrator and sends

out Router Advertisement announcements onto the link. These announcements can allow

the on-link connected IP phone to configure itself with IPv6 address, as specified in RFC

4862.

 Stateful DHCPv6: The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) has been

standardized by the IETF through RFC 3315. DHCPv6 enables DHCP servers to pass

configuration parameters such as IPv6 network addresses to IPv6 nodes. It offers the

capability of automatic allocation of reusable network addresses and additional

configuration flexibility. This protocol is a stateful counterpart to “IPv6 Stateless Address

Autoconfiguration” (RFC 2462), and can be used separately or concurrently with the latter

to obtain configuration parameters.

VPN

VPN (Virtual Private Network) is a secured private network connection built on top of public

telecommunication infrastructure, such as the Internet. It has become more prevalent due to

benefits of scalability, reliability, convenience and security. VPN provides remote offices or

individual users with secure access to their organization's network.

Types of VPN Access

There are two types of VPN access: remote-access VPN (connecting an individual device to a

network) and site-to-site VPN (connecting two networks together). Remote-access VPN allows

employees to access their company's intranet from home or outside the office, and site-to-site

VPN allows employees in geographically separated offices to share one cohesive virtual network.

VPN can be also classified by the protocols used to tunnel the traffic. It provides security

through tunneling protocols: IPSec, SSL, L2TP and PPTP.

VPN Technology

IP phones support SSL VPN, which provides remote-access VPN capabilities through SSL.

OpenVPN is a full featured SSL VPN software solution that creates secure connections in remote

access facilities, designed to work with the TUN/TAP virtual network interface. TUN and TAP are

virtual network kernel devices. TAP simulates a link layer device and provides a virtual

point-to-point connection, while TUN simulates a network layer device and provides a virtual

network segment.

Parameters

Permitted Values

Default

static.network.vpn_enable

0 or 1

Description:

IP phones use OpenVPN to achieve VPN feature. To prevent disclosure of private information,

tunnel endpoints must authenticate each other before secure VPN tunnel is established. After

VPN feature is configured properly on the IP phone, the IP phone acts as a VPN client and uses

the certificates to authenticate the VPN server.

To use VPN, the compressed package of VPN-related files should be uploaded to the IP phone

in advance. The file format of the compressed package must be *.tar. The related VPN files are:

certificates (ca.crt and client.crt), key (client.key) and the configuration file (vpn.cnf) of the VPN

client.

The following table lists the unified directories of the OpenVPN certificates and key in the configuration file (vpn.cnf) for Yealink IP phones:
