Transport Layer Security (TLS)
TLS is a commonly-used protocol for providing communications privacy and managing the security of message trans-

visioning in a way that is designed to prevent eavesdropping and tampering.
Yealink phones support TLS version 1.0, 1.1 and 1.2. When TLS is enabled for an account, the SIP message of this
account will be encrypted, and a lock icon appears on the LCD screen after the successful TLS negotiation.
