Yealink IP Phones Auto Provisioning Guide

Yealink IP phones allow you to upgrade firmware manually via web user interface, or
upgrade firmware in batch via auto provisioning.
The following table lists the firmware name for the phone model (X is replaced by the
actual firmware version):
Phone Model
Firmware Name
SIP-T23 (P/G)
44.x.x.x.rom
To upgrade the IP phones firmware in batch via auto provisioning, ask the distributor for
the firmware file, upload it to the provisioning server, and then specify the access URL in
configuration files.
##Specify the access URL of the firmware file.
firmware.url =
For example, enter tftp://admin:password@192.168.1.100/44.80.0.1.rom (admin is
replaced by the authentication user name and password is replaced by the
authentication password) in the “firmware.url =” field. During the auto provisioning
process, the IP phone connects to the provisioning server 192.168.1.100, and
downloads the firmware file 44.80.0.5.rom.
For more information on the parameter, refer to Description of Configuration Parameters
in CFG Files on page 81.
