When SRTP is enabled on both IP phones, RTP streams will be encrypted, and a lock icon appears on the LCD screen of
each IP phone after successful negotiation.
Note
If you enable SRTP, then you should also enable TLS. This ensures the security of SRTP encryption. For more information on
TLS, refer to Transport Layer Security (TLS).

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:
l Configuration files: MAC-Oriented CFG file (<MAC>.cfg), Common CFG file (y0000000000xx.cfg), MAC-local CFG
file (<MAC>-local.cfg) or other custom CFG files (for example, sip.cfg, account.cfg)
l Contact Files: <MAC>-contact.xml
To encrypt/decrypt files, you may have to configure an AES key.
Note
aES keys must be 16 characters. The supported characters contain: 0 ~ 9, A ~ Z, a ~ z and special characters: # $ % * + , - . : =
? @ [ ] ^ _ { } ~.
