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 “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”.

Parameter
static.autoprovision.X.com_aes
[1][2]
<y0000000000xx>.cfg
Description
It configures the plaintext AES key for decrypting the Common CFG file.
If it is configured, it has a higher priority than the value configured by the parameter “static.auto_pro-
vision.aes_key_16.com”.

Default Blank
Parameter
static.autoprovision.X.mac_aes

Description It enables or disables the IP phone to encrypt <MAC>-contact.xml file using the plaintext AES key.
Permitted
Values
0-Disabled, the contact 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 contacts to the server by the para-
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_16.mac”.
