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.

Getting Started

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.

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 57.
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.
