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-T28P
Yealink SIP-T26P
Yealink SIP-T22P
Yealink SIP-T21P
Yealink SIP-T20P
Yealink SIP-T19P
Yealink SIP-T46G
Yealink SIP-T42G
Yealink SIP-T41P
The auto provisioning process outlined in this guide applies to Yealink IP phones running
firmware V72 or later. We recommend that IP phones running firmware V72 or later
CANNOT be downgraded to an earlier firmware version. The new firmware is compatible
with old configuration parameters, but not vice versa.
This guide is also applicable to SIP-T21, SIP-T20 and SIP-T19 IP phones running firmware V72
or later, which are not PoE-compliant.

Getting Started
3
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 two
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 with the same model. It
uses a fixed name “y0000000000XX.cfg”or “y00000000000X.cfg”as the file name,
where "XX" or “X”equals to the first two digits or the first digit of the hardware version
of the phone model (except 0 for SIP-T28P).
The names of the Common CFG file for each phone model are:
Phone Model
Common CFG File
SIP-T28P
y000000000000.cfg
SIP-T26P
y000000000004.cfg
SIP-T22P
y000000000005.cfg
SIP-T21P
y000000000034.cfg
SIP-T20P
y000000000007.cfg
SIP-T19P
y000000000031.cfg
SIP-T46G
y000000000028.cfg
SIP-T42G
y000000000029.cfg

You can ask the distributor or Yealink FAE for configuration files. The IP phones running
firmware version 71 or later 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 IP address of the SIP server. Ask your system administrator for SIP account
information.
Auto provisioning enables Yealink 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 63.
