Transport Layer Security (TLS)
TLS is a commonly-used protocol that provides communications privacy and manages the security of message
transmission, allowing the phones to communicate with other remote parties and connect to the HTTPS URL for
provisioning in a way that is designed to prevent eavesdropping and tampering.
Yealink Teams IP phones support TLS 1.0, TLS 1.1 and TLS 1.2.
