Downloading and Verifying Configurations

on Page 41.
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 and 001565770984.cfg files in sequence,
and then updates configurations in the downloaded configuration files orderly to the IP
phone system. As the value of the parameter ―auto_provision.custom.protect‖ is set to 1,
configurations in the 001565770984-local.cfg file saved on the IP phone are also
updated.
The IP phone starts up successfully, and personalized settings are remained after auto
provisioning. When a user customizes feature configurations via web/phone user
interface, the IP phone will save the personalized settings to the 001565770984-local.cfg
file on the IP phone only.
If value of the parameter ―auto_provision.custom.protect‖ is set to 0, the personalized
settings in the 001565770984-local.cfg file will be overridden after auto provisioning, no
matter what the value of the parameter ―auto_provision.custom.sync‖ is.
The administrator or user wishes to clear personalized configuration settings via phone
user interface.
Scenario Conditions:

SIP-T23G IP phone MAC: 001565770984

The current firmware of the phone is 44.80.0.5 or later.

Provisioning server URL: tftp://192.168.1.211
If a configuration is modified via both web user interface and phone user interface, the
later modification will prevail.
For more information on the flowchart of protect personalized configuration settings,
refer to Auto Provisioning Flowchart (Protect personalized configuration settings) on
page 90.
In this scenario, the IP phone will not upload the MAC-local.cfg file to provisioning server
and request to download the MAC-local.cfg file from provisioning server during auto
provisioning.
If a configuration item is both in the MAC-local.cfg file on the IP phone and Common CFG
file/ MAC-Oriented CFG file downloaded from auto provisioning server, setting of the
configuration item in the MAC-local CFG file will be written and saved to the IP phone
system.
