After startup, all configurations of the phone will be reset to factory defaults.
Configurations in the 001565770984-local.cfg file saved on the IP phone will also be
cleared. But configurations in the 001565770984-local.cfg file stored on the
provisioning server (tftp://192.168.1.211) will not be cleared after reset.
To retrieve personalized settings of the phone after factory reset:
1. Set the values of the parameters “auto_provision.custom.sync” and
“auto_provision.custom.protect” to be 1 in the configuration file (y000000000044.cfg
or 001565770984.cfg).
2. Trigger the phone to perform the auto provisioning process.
The IP phone will download the 001565770984-local.cfg file from the provisioning
server, and then update configurations in it during auto provisioning. As a result, the
personalized settings of the phone are retrieved after factory reset.
