During auto provisioning, the DECT IP phone first downloads the y000000000077.cfg file, and
then downloads firmware from the root directory of the provisioning server.
The DECT 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 y000000000077.cfg and 001565770984.cfg files in sequence, and then updates
configurations in the downloaded configuration files orderly to the DECT 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 DECT IP phone are also updated. The DECT IP phone
starts up successfully, and personalized settings are kept after auto provisioning.
When a user customizes feature configurations via web/handset user interface, the DECT IP
phone will save the personalized settings to the 001565770984-local.cfg file on the DECT IP
phone only.
Note
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 the 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.
Keep user personalized configuration settings of the Handset
The handset settings can be configured via handset user interface or auto provisioning. The
personalized handset settings stand for the handset settings configured via handset user
interface. The administrator wishes to change some handset settings via auto provisioning, but
protect personalized handset settings after auto provisioning.
Scenario Conditions:
The current firmware version of the W60B base station and W56H handset are 77.81.0.10

and 61.81.0.30 respectively. This firmware version supports protecting personalized
handset settings after auto provisioning.
Provisioning server URL: tftp://192.168.1.211.

To configure the handset settings via auto provisioning, you need to configure the value of the
parameter "auto_provision.handset_configured.enable" to 1. To protect personalized handset
settings after auto provisioning, you need to configure the value of the parameter
"auto_provision.custom.protect" to 1.
Do the following operations:
Add/Edit the following parameters in the y000000000077.cfg file or 001565770984.cfg file
1.
