Downloading and Verifying Configurations

phone will save the personalized configuration settings to the 00156574b150-local.cfg
file on the IP phone, and then periodically (every 5 minutes) upload this file to the
provisioning server.
Scenario Operations II:
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=0
#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 and 00156574b150.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 00156574b150-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 00156574b150-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 00156574b150-local.cfg file will be overridden after auto provisioning, no
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.
If a configuration item is both in the downloaded MAC-local.cfg file and Common CFG
file/ MAC-Oriented CFG file, setting of the configuration item in the MAC-local CFG file
will be written and saved to the IP phone system.
