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-T23

Yealink SIP-T23P

Yealink SIP-T23G
The auto provisioning process outlined in this guide applies to Yealink SIP-T23 (P/G) IP
phones running firmware version X.80.0.5 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.
