VPN
The VPN (Virtual Private Network) technology establishes a private tunnel on the public network through
key exchange, encapsulation, authentication and encryption, to ensure the integrity, privacy, and validity
of the transmitted data. VCS uses OpenVPN to achieve VPN feature. To prevent disclosure of private
information, tunnel endpoints must authenticate each other before the secure VPN tunnel is established.
After you configure VPN feature on the system, the system will act as a VPN client and uses the
certificates to authenticate with the VPN server.
For more information, refer to OpenVPN Feature on Yealink IP Phones.
