Yealink T58A

| Security Features | 89
Permitted Values
0-Disabled, the device will decrypt the encrypted configuration files using plaintext
AES keys configured on the device.
1-Enabled, the device 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 device built-in key (for example, key1). The device 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: # $ % * + , - . : = ? @ [ ] ^ _ { } ~.
Example:
static.auto_provision.aes_key_16.com = 0123456789abcdef
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 device will try to encrypt/
decrypt the MAC-Oriented file using the AES key configured by the parameter
“static.auto_provision.aes_key_16.com”.
Permitted Values 16 characters
Default Blank

Parameter static.auto_provision.aes_key_16.mac <y0000000000xx>.cfg
Description
It 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 “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 device will try to encrypt/
decrypt the MAC-Oriented file using the AES key configured by the parameter
“static.auto_provision.aes_key_16.com”.
Permitted Values 16 characters
