symmetric keys during auto provisioning. If the parameter “
static.auto_provision.aes_key_16.mac
” is left
blank, the value of the parameter “
static.auto_provision.aes_key_16.com
” will be used.
If the downloaded contact files is encrypted, the IP phone will try to decrypt <MAC>-contact.xml file
using the plaintext AES key. After decryption, the IP phone resolves contact files and updates contact
information onto the IP phone system.
Encryption and Decryption Configuration
The following table lists the parameters you can use to configure the encryption and decryption.
Parameter static.auto_provision.update_file_mode
<y0000000000xx>.cfg
Description It enables or disables the IP phone only to download the encrypted files.
Permitted
Values
0-Disabled, the IP phone will download the configuration files (for example, sip.cfg,
account.cfg, <MAC>-local.cfg) and <MAC>-contact.xml file from the server during
auto provisioning no matter whether the files are encrypted or not. And then resolve
these files and update settings onto the IP phone system.
1-Enabled, the IP phone will only download the encrypted configuration files (for
example, sip.cfg, account.cfg, <MAC>-local.cfg) or <MAC>-contact.xml file from the
server during auto provisioning, and then resolve these files and update settings onto
the IP phone system.
Default 0
Parameter static.auto_provision.aes_key_in_file
<y0000000000xx>.cfg
Description
It enables or disables the IP phone to decrypt configuration files using the encrypted
AES keys.
Permitted
Values
0-Disabled, the IP phone will decrypt the encrypted configuration files using plaintext
AES keys configured on the IP phone.
1-Enabled, the IP phone will download <xx_Security>.enc files (for example,
<sip_Security>.enc, <account_Security>.enc) during auto provisioning, and then
decrypts these files into the plaintext keys (for example, key2, key3) respectively using
the phone built-in key (for example, key1). The IP phone then decrypts the encrypted
configuration files using corresponding key (for example, key2, key3).
Default 0
Parameter static.auto_provision.aes_key_16.com
<y0000000000xx>.cfg
Description
It 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: # $ % * + , - . : = ? @ [ ] ^ _ { } ~.
