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
configured by the parameter “static.auto_provision.aes_key_16.com”.
Web User Interface:
Settings->Auto Provision->Common AES Key
Phone User Interface:
Menu->Advanced (default password: admin) ->Auto Provision->Common
static.auto_provision.aes_key_16.mac
16 characters
Blank
Description:
Configures the plaintext AES key for encrypting/decrypting the MAC-Oriented files
(<MAC>.cfg, <MAC>-local.cfg and <MAC>-contact.xml).
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.mac = 0123456789abmins
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
