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 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”.
