Encrypting and Decrypting Files
Yealink IP phones support downloading encrypted files from the server and encrypting files
before/when uploading them to the server. You can encrypt the following files: MAC-Oriented
CFG file (<MAC>.cfg), Common CFG file (y0000000000xx.cfg), MAC-local CFG file
(<MAC>-local.cfg) or other custom CFG files (e.g., sip.cfg, account.cfg)
To encrypt/decrypt files, you may have to configure an AES key.
