Administrators Guide for SIP-T2 Series/T19(P) E2/T4 Series/T5 Series/CP860/CP920 IP Phones
166
To retrieve personalized settings of the phone after factory reset:
1. Set the values of the parameters static.auto_provision.custom.sync and
static.auto_provision.custom.protect” to be 1 in the configuration file (y000000000028.cfg
or 001565770984.cfg).
2. Trigger the phone to perform the auto provisioning process.
As the value of the parameter static.auto_provision.custom.sync” is set to 1, the IP phone will
download the 001565770984-local.cfg file from the provisioning server to override the one
stored on the phone. So the configurations in 001565770984-local.cfg file will be updated and
stored on the IP phone during auto provisioning. As the value of the parameter
static.auto_provision.custom.protect” is set to 1, the personalized configuration settings will be
kept after auto provisioning. As a result, the personalized configuration settings of the phone
are retrieved after factory reset.
Scenario D Import or export the local configuration file
The administrator or user can export the local configuration file to check the
personalized settings of the phone configured by the user, or import the local
configuration file to configure or change settings of the phone.
Scenario Conditions:
SIP-T46G IP phone MAC: 001565770984
The current firmware of the phone is 28.81.0.10 or later.
Provisioning server URL: tftp://192.168.1.211
Note
Scenario Operations:
To export local configuration file via web user interface:
1. Click on Settings->Configuration.
As the personalized settings of the phone cannot be changed via auto provisioning when the
value of the parameter “static.auto_provision.custom.protect” is set to 1, it is cautious to change
the settings in the <MAC>-local.cfg file before importing it.
