static.auto_provision.aes_key_in_file
0 or 1
0
Description:
Enables or disables the IP phone to decrypt configuration files using the encrypted AES keys.
0-Disabled
1-Enabled
If it is set to 0 (Disabled), the IP phone will decrypt the encrypted configuration files using
plaintext AES keys configured on the IP phone.
If it is set to 1 (Enabled), the IP phone will download <xx_Security>.enc files (e.g.,
<sip_Security>.enc, <account_Security>.enc) during auto provisioning, and then decrypts
these files into the plaintext keys (e.g., key2, key3) respectively using the phone built-in key
(e.g., key1). The IP phone then decrypts the encrypted configuration files using
corresponding key (e.g., key2, key3).

static.auto_provision.aes_key_16.com
16 characters
Blank
Description:
Configures the plaintext AES key for encrypting/decrypting the Common CFG/Custom CFG
file.
The valid characters contain: 0 ~ 9, A ~ Z, a ~ z and the following special characters are also
supported: # $ % * + , - . : = ? @ [ ] ^ _ { } ~.
Example:
static.auto_provision.aes_key_16.com = 0123456789abcdef
Note: For decrypting, it works only if the value of the parameter
“static.auto_provision.aes_key_in_file” is set to 0 (Disabled). If the downloaded
MAC-Oriented file is encrypted and the parameter “static.auto_provision.aes_key_16.mac” is
left blank, the IP phone will try to encrypt/decrypt the MAC-Oriented file using the AES key
