Introduction
1
Yealink SIP-T4X 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 SIP-T4X IP phones with the
minimum settings required. Yealink SIP-T4X 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 SIP-T4X
IP phones, including:
SIP-T46G
SIP-T42G
SIP-T41P
The auto provisioning process outlined in this guide applies to Yealink SIP-T4X IP phones
running firmware version 71 or later.

This section provides instructions on how to get ready for auto provisioning. The auto
provisioning process discussed in this guide uses the TFTP server as the provisioning
server.
To begin the auto provisioning process, the following steps are required:
Obtaining Configuration Information
Managing Configuration Files
Before beginning provisioning, you need to obtain configuration files. There are 2
configuration files both of which are CFG-formatted. We call these two files Common
CFG file and MAC-Oriented CFG file. The phone tries to download these CFG files from
the server during provisioning.
The MAC-Oriented CFG file is only effectual for the specific phone. It uses the 12-digit
MAC address of the phone as the file name. For example, if the MAC address of the
phone is 0015651130F9, the MAC-Oriented CFG file name must be 0015651130F9.cfg.
However, the Common CFG file is effectual for all the phones of the same model. It uses
a fixed name “y0000000000XX.cfg” as the file name, where "XX" equals to the hardware
version of the phone model.
The names of the Common CFG file for SIP-T4X IP phones are:
Phone Model
Common Configuration File
SIP-T46G
y000000000028.cfg
SIP-T42G
y000000000029.cfg
SIP-T41P
y000000000036.cfg
You can ask the distributor or Yealink FAE for configuration files. The IP phones can only
recognize configuration files using UTF-8 or ANSI encoding.
Before beginning provisioning, you also need the phone information. For example, MAC
address and the SIP account information of the phone.

Yealink SIP-T4X IP Phones Auto Provisioning Guide
4
MAC Address: The unique 12-digit serial number of the phone. You can obtain it from the
bar code on the back of the phone.
SIP Account Information: This may include SIP credentials such as user name, password
and address of the registration server. Ask your system administrator for SIP account
information.
Auto provisioning enables IP phones to update themselves automatically via
downloading Common CFG and MAC-Oriented CFG files. Before beginning
provisioning, you may need to edit and customize your configuration files. For more
information on configuration parameters in configuration files, refer to Description of
Configuration Parameters in CFG Files on page 58.
Common CFG file contains configuration parameters which apply to phones with the
same model, such as language, time and date.
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.

To protect against unauthorized access and tampering of sensitive information (e.g.,
login passwords, registration information), you can encrypt configuration files using
Yealink Configuration Conversion Tool. AES keys must be 16 characters and the
supported characters contain: 0 ~ 9, A ~ Z, a ~ z, and the special characters # $ % * +,
- . : = ? @ [ ] ^ _ { } ~. For more information on how to encrypt configuration files, refer
to Yealink Configuration Conversion Tool User Guide .
AES keys must be configured on the phone before the auto provisioning process. AES
keys are configurable via web user interface at the path: Settings->Auto
Provision->Common AES Key (and MAC-Oriented AES Key).
When configuring some particular features, you may need to upload resource files to IP
phones, such as personalized ringtone file, language package. Yealink provides some
resource file templates for the particular features. Ask the distributor or Yealink FAE for
resource file templates. The following provides information on how to customize
resource files and specify the access URL for the resource files.

Yealink SIP-T4X IP Phones Auto Provisioning Guide
12
The IP phones have built-in system ringtones. You can change the ring type, or customize
a ringtone and upload it to the phone via auto provisioning.
The ringtone file must be PCMU audio format, mono channel, 8K sample rate and 16 bit
resolution.
The ringtone file format must be *.wav.
The ringtone file uploaded must be within 100KB.
####################################################
## Configure the access URL of the customized ringtone ##
####################################################
ringtone.url =
#Delete all the custom ringtones uploaded through auto provisioning
ringtone.delete = http://localhost/all
For example, enter “tftp://192.168.1.100/Ring9.wav” in the “ringtone.url =” field. During
the auto provisioning process, the phone connects to the provisioning server
“192.168.1.100”, and downloads the ringtone file “Ring9.wav”.
For more information on customizing a ringtone file, refer to Customizing a Ringtone
Using Cool Edit Pro on page 55.
You can modify the language translation for the phone user interface, and add a new
language to the phone. To modify or add a language, you need to edit the language
file, upload it to the provisioning server, and then specify the access URL in the
configuration file.
The following table lists available languages and the associated language files for the
phone user interface:

To update translation of a built-in language, you should modify translation items in the
language file, upload the file to the root directory of the provisioning server, and trigger
an auto provisioning process for update. The file name of the language file cannot be
changed.
To add a new translation language, you should add and edit a new language file
named as “X.GUI.Y.lang”for SIP-T46G IP phones or “lang-Y.txt”for SIP-T42G/T41P IP
phones, upload the file to the directory of the provisioning server, and trigger an auto
provisioning process for update. “X”in the language file name is an integer which starts
from 10. “Y”in the language file name means the name of the new added language.
For example, you want to add a new translation language “Korean”for SIP-T46G IP
phones. The file name of the new added language file should be “10.GUI.Korean.lang”.
After update, you will find a new language selection named as “Korean”on the phone
user interface: Menu->Basic->Language.
The following figure shows a portion of the SIP-T46G English language file:
You can also define the name of the new added language by editing the parameter
SIP-T46G IP phones also support .txt format language files. The names of the .txt
language files for SIP-T46G IP phones are the same as that of the SIP-T42G/T41P IP
phones.

“Name=”in the language file for SIP-T46G IP phones. For example, edit the value of the
parameter “Name=”to be “en-us”in the “0.GUI.English.lang”language file. After
update, you will find the English language selection on the phone user interface is
“en-us”.
The following figure shows a portion of the SIP-T42G English language file:
####################################################
## Configure the access URL of the LCD language file ##
####################################################
gui_lang.url =
#Delete all custom languages through auto provision
gui_lang.delete = http://localhost/all
If you want to add a new language Russian to the phone, configure the parameter
“gui_lang.url =” in the configuration file, for example:
gui_lang.url = tftp://192.168.1.100/10.GUI.Russian.lang ## For SIP-T46G##
gui_lang.url = tftp://192.168.1.100/lang-Russian.txt ##For SIP-T42G/T41P##
During the auto provisioning process, the phone connects to the provisioning server
“192.168.1.100”, and downloads the language file. After update, you will find a new
language selection “Russian”on the phone user interface.
Available languages may vary between different firmware versions.
Do not rename the language file.
