The administrator wishes to upgrade firmware from the old version to the latest version.
Meanwhile, protect personalized settings after auto provisioning and upgrade.
Scenario Conditions:

SIP-T23G IP phone current firmware version: 44.80.0.1. This firmware supports
protecting personalized settings and generating a <MAC>-local.cfg file.

SIP-T23G IP phone target firmware version: 44.80.0.5. This firmware supports
support protecting personalized settings and generating a <MAC>-local.cfg file.

SIP-T23G IP phone MAC: 00156574b150

Provisioning server URL: tftp://192.168.1.211

Place the target firmware to the root directory of the provisioning server.
The old firmware version supports protecting personalized settings and generating a
<MAC>-local.cfg file. To protect personalized settings after auto provisioning and
upgrade, you need to configure the value of the parameter
“auto_provision.custom.protect” to 1 in the configuration file.
Do one of the following operations:
Scenario Operations I:
1. Add/Edit the following parameters in the y000000000044.cfg file or
00156574b150.cfg file you want the IP phone to download:
auto_provision.custom.protect=1
auto_provision.custom.sync=1
#Configure the access URL of the firmware file.
firmware.url = tftp://192.168.1.211/44.80.0.5.rom
2. Trigger the IP phone to perform the auto provisioning process. For more information
on how to trigger auto provisioning process, refer to
Configuring the Update Mode
on Page 37 .
During auto provisioning, the IP phone first downloads the y000000000044.cfg file, and
then downloads firmware from the root directory of the provisioning server.
The IP phone reboots to complete firmware upgrade, and then starts auto provisioning
process again which is triggered by phone reboot (the power on mode is enabled by
default). It downloads the y000000000044.cfg, 00156574b150.cfg and the
00156574b150-local.cfg file in sequence from the provisioning server, and then updates
configurations in these downloaded configuration files orderly to the IP phone system.
The IP phone starts up successfully, and the personalized settings in the
00156574b150-local.cfg file are remained after auto provisioning.
When a user customizes feature configurations via web/phone user interface, the IP
