Downloading and Verifying Configurations

The IP phone 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, the phone also updates the configurations stored in the 001565221229-local.cfg

file on the phone. As a result, the personalized settings of the old firmware are

remained after upgrade and auto provisioning.

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-T28P IP phone current firmware version: 2.72.0.30. This firmware version supports

protecting personalized settings and generating a <MAC>-local.cfg file.



SIP-T28P IP phone target firmware version: 2.73.0.1. This firmware supports support

protecting personalized settings and generating a <MAC>-local.cfg file.



SIP-T28P IP phone MAC: 001565221229



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 y000000000000.cfg file or

001565221229.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://192.168.1.211/2.73.0.1.rom

2. Trigger the IP phone to perform the auto provisioning process. For more information

on how to trigger auto provisioning process, refer to on Page 45.

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.
