meter “static.auto_provision.local_contact.backup.enable”.
1-Enabled, the contact file will be uploaded encrypted and will replace the one (encrypted or unen-
crypted) stored on the server if you have configured to back up the contacts to the server by the para-
meter “static.auto_provision.local_contact.backup.enable”. The plaintext AES key is configured by the
parameter “static.auto_provision.aes_key.mac”.
Default
0
Parameter
static.auto_provision.encryption.call_log <y0000000000xx>.cfg
Description
It enables or disables the phone to encrypt <MAC>-calllog.xml file using the plaintext AES key.
Permitted
Values
0-Disabled, the call log file will be uploaded unencrypted and will replace the one (encrypted or unen-
crypted) stored on the server if you have configured to back up the call log to the server by the para-
meter “static.auto_provision.local_calllog.backup.enable”.
1-Enabled, the call log file will be encrypted uploaded and will replace the one (encrypted or unen-
crypted) stored on the server if you have configured to back up the call log to the server by the para-
meter “static.auto_provision.local_calllog.backup.enable”. The plaintext AES key is configured by the
parameter “static.auto_provision.aes_key.mac”.
Default
0
Parameter
static.auto_provision.encryption.config <y0000000000xx>.cfg
Description
It enables or disables the phone to encrypt <MAC>-local.cfg file using the plaintext AES key.
Permitted
Values
0-Disabled, the MAC-local CFG file will be uploaded unencrypted and will replace the one (encrypted
or unencrypted) stored on the server if you have configured to back up the MAC-local CFG file to the
server by the parameter “static.auto_provision.custom.sync”.
1-Enabled, the MAC-local CFG file will be uploaded encrypted and will replace the one (encrypted or
unencrypted) stored on the server if you have configured to back up the MAC-local CFG file to the
server by the parameter “static.auto_provision.custom.sync”. The plaintext AES key is configured by
the parameter “static.auto_provision.aes_key.mac”.
Default
0
Parameter
static.auto_provision.rsa_pri_key.url <y0000000000xx>.cfg
Description
It configures the URL to import the self-define RSA private key file.
Note: The key file must be in *.key format. It works only if "static.auto_provision.rsa_pri_key.enable" is
set to 1 (Enabled).
Permitted
Values
URL within 511 characters
Default
Blank
