Introduction
1
Yealink IP phones are full-featured telephones that can be plugged directly into an IP
network and can be used easily without manual configuration.
This guide provides instructions on how to provision Yealink IP phones with the minimum
settings required. Yealink IP phones support FTP, TFTP, HTTP, and HTTPS protocols for auto
provisioning and are configured by default to use the TFTP protocol.
The purpose of this guide is to serve as a basic guidance for provisioning Yealink IP
phones, including:
Yealink SIP VP-T49G
Yealink SIP-T48G
Yealink SIP-T46G
Yealink SIP-T42G
Yealink SIP-T41P
Yealink SIP-T40P
Yealink SIP-T29G
Yealink SIP-T27P
Yealink SIP-T23P/G
Yealink SIP-T21(P) E2
Yealink SIP-T19(P) E2
Yealink CP860
Yealink W56P
The auto provisioning process outlined in this guide applies to Yealink SIP
VP-T49G/SIP-T48G/T46G/T42G/T41P/T40P/T29G/T27P/T23P/T23G/T21(P) E2/T19(P) E2,
CP860, W56P IP phones running firmware version 80 or later. We recommend that IP
phones running the latest firmware CANNOT be downgraded to an earlier firmware
version. The new firmware is compatible with old configuration parameters, but not
vice versa.

Getting Started
3
This section provides instructions on how to get ready for auto provisioning. To begin the
auto provisioning process, the following steps are required:
Obtaining Configuration Files
Obtaining Phone Information
Before beginning provisioning, you need to obtain configuration files. There are two
configuration files both of which are CFG-formatted. We call these two files Common
CFG file and MAC-Oriented CFG file. The IP phone tries to download these CFG files
from the server during auto provisioning.
IP phones also support a local configuration file named as <MAC>-local.cfg. When a
user modifies configurations via web user interface or phone user interface, the
configurations will be automatically saved to the MAC-local CFG file on the IP phone.
You can ask the distributor or Yealink FAE for Common CFG and MAC-Oriented files. You
can also obtain the Common CFG file and MAC-Oriented file online:
http://support.yealink.com/documentFront/forwardToDocumentFrontDisplayPage.
To download Common CFG and MAC-Oriented files:
1. Go to Yealink Document Download page and select the desired phone model.
2. Download and extract the combined configuration files to your local system.
For W56P, the <MAC>-local.cfg file only saves configurations of the base station
configured via the handset or web user interface. Configurations of the handset cannot
be saved to the <MAC>-local.cfg file.

For example, the following illustration shows the template files available for
SIP-T23G IP phones running firmware version 80.
3. Open the folder you extracted and identify the files you will edit.
Before beginning provisioning, you also need the IP phone information. For example,
MAC address and the SIP account information of the IP phone.
MAC Address: The unique 12-digit serial number of the IP phone. You can obtain it from
the bar code on the back of the IP phone. For W56P, you can obtain it from the bar code
on the back of the base station
SIP Account Information: This may include SIP credentials such as user name, password
and IP address of the SIP server. Ask your system administrator for SIP account
information.

This section provides instructions on how IP phones interoperate with provisioning server
for auto provisioning, and shows you four major tasks to provision the phones. It will help
users who are not familiar with auto provisioning to understand this process more easily
and quickly.
When IP phones are triggered to perform auto provisioning, it will request to download
the configuration files from the provisioning server. During the auto provisioning process,
the IP phone will download and update configuration files to the phone flash.
The following figure shows how the IP phone interoperates with the provisioning server:

Yealink IP Phones Auto Provisioning Guide
6
When IP DECT phone is triggered to perform auto provisioning, the base station will
requeset to download the configuration files from the provisioning sever. During the
auto provisioning process, the base station will download and update configuration
files to the phone flash, and then deliver the handset configurations to the registered
handset. Handset reboot or registration will also trigger the base station to deliver the
stored handset settings to the handset.
The following figure shows how the IP DECT phone interoperates with the provisioning
server:

This section shows an instance of auto provision configuration.
1. Manage configuration files.
Add/Edit the desired configuration parameters in the CFG file (e.g.,
y000000000044.cfg) you want the IP phone to download. For more information on
how to manage configuration files, refer to Managing Configuration Files on page
11.
2. Configure the TFTP server.
1) Place configuration files to TFTP root directory (e.g., D:\TFTP Directory).
2) Start the TFTP sever. The IP address of the TFTP server is shown as below:

3) Select Configure TFTP Server. Click the button to locate the TFTP root
directory from your local system.
For more information on how to configure a provisioning server, refer to Configuring
a Provisioning Server on page 17.
3. Configure the provisioning server address on the IP phone.
For more information on how to obtain the provisioning server address, refer to
Obtaining the Provisioning Server Address on page 21.

4. Trigger the IP phone to perform the auto provisioning.
For more information on how to trigger the phone to perform the auto provisioning, refer
to Triggering the IP Phone to Perform the Auto Provisioning on page 31.

Managing Configuration Files
11
Auto provisioning enables Yealink IP phones to update themselves automatically via
downloading Common CFG, MAC-Oriented CFG and MAC-local CFG files. Before
beginning provisioning, you may need to edit and customize your configuration files.
You can edit the template files directly or create a new CFG file as required. Open each
configuration file with a text editor such as UltraEdit.
For more information on description of all configuration parameters in configuration files,
refer to Yealink_SIP-T2_Series_T19(P) E2_T4_Series_CP860 IP phones_Description of
Configuration Parameters in CFG Files.xlsx .
For W56P, refer to Yealink IP Dect Phones Description of Configuration Parameters in CFG
Files.xlsx .
The Common CFG file is effectual for all phones of the same model. It uses a fixed name
“y0000000000XX.cfg”as the file name, where "XX" equals to the first two digits of the
hardware version of the IP phone model.
The names of the Common CFG file requirements for the phone model are:
Phone Model

same model, such as language and volume.
The following figure shows a portion of the common CFG file:
When editing the Common CFG file, learn the following:
The line beginning with “#”is considered to be a comment.
The file header “#!version:1.0.0.1”is not a comment and must be placed in the first
line. It cannot be edited or deleted.
The file format must be *.cfg.
The filename complies with the requirements that are listed in the above table.
Each line must use the following format and adhere to the following rules:
Configuration Parameter=Valid Value
-Separate each configuration parameter and value with an equal sign.
-Set only one configuration parameter per line.
-Put the configuration parameter and value on the same line, and do not break
the line.
The MAC-Oriented are only effectual for the specific phone. They use the 12-digit MAC
address of the IP phone as the file name. For example, if the MAC address of the IP
phone is 0015651130F9, the MAC-Oriented CFG file has to be named as
0015651130f9.cfg (case-sensitive) respectively.
MAC-Oriented CFG file contains configuration parameters which are expected to be
updated per phone, such as the registration information.

The following figure shows a portion of the MAC-Oriented CFG file:
When editing the MAC-Oriented CFG file, learn the following:
The line beginning with “#”is considered to be a comment.
The file header “#!version:1.0.0.1”is not a comment and must be placed in the first
line. It cannot be edited or deleted.
The file format must be *.cfg.
The filename matches the MAC address of your phone.
Each line must use the following format and adhere to the following rules:
Configuration Parameter=Valid Value
-Separate each configuration parameter and value with an equal sign.
-Set only one configuration parameter per line.
-Put the configuration parameter and value on the same line, and do not break
the line.
If you want to create a new CFG file for your phone, follow these steps:
To create a new CFG file:
1. Create a CFG file for your phone. Ensure the file complies with the guidelines that
are listed in Editing Common CFG File on page 11 or Editing MAC-Oriented CFG
File on page 12.
SIP VP-T49G/SIP-T48G/T46G/T29G IP phones support 16 accounts, SIP-T42G IP phones
support 12 accounts, SIP-T41P/T27P IP phones support 6 accounts, W56P IP phones
support 5 accounts, SIP-T40P/T23P/T23G IP phones support 3 accounts, SIP-T21(P) E2 IP
phones support 2 accounts, SIP-T19 (P) E2 and CP860 IP phones support only one
account.

2. Copy configuration parameters from the template configuration files and set the
valid values for them.
3. Save the changes and close the CFG file.
MAC-local CFG file automatically stores configurations modified via web user interface
or phone/handset user interface. The file is stored locally on the IP phone, but a copy
can also be uploaded to the provisioning server. The file enables the phone to keep user
personalization settings, even after auto provision. As with the MAC-Oriented CFG files,
MAC-local CFG files are only effectual for the specific phone too. They use the 12-digit
MAC address of the IP phone as the file name. For example, if the MAC address of the
IP phone is 0015651130F9, MAC-local CFG file has to be named as
0015651130f9-local.cfg (case-sensitive) respectively.
If your IP phone‟s current firmware version doesn‟t support generating a
<MAC>-local.cfg file, the IP phone will automatically generate a MAC-local CFG file
after it is upgraded to the latest firmware.
For W56P, the <MAC>-local.cfg file only saves configurations of the base station
configured via the handset or web user interface. Configurations of the handset cannot
be saved to the <MAC>-local.cfg file.
