TLS is a commonly-used protocol for providing communications privacy and managing the security
of message transmission, allowing IP 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.
Halo series 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.

TLS Configuration
A cipher suite is a named combination of authentication, encryption, and message authentication
code (MAC) algorithms used to negotiate the security Settings for a network connection using the
TLS/SSL network protocol.
