VPN
Yealink IP phones use OpenVPN to achieve VPN feature. To prevent disclosure of private information, tunnel endpoints
must authenticate each other before secure VPN tunnel is established. After you configure VPN feature on the IP
phone, the IP phone will act as a VPN client and use the certificates to authenticate with the VPN server.
For more information, refer to OpenVPN Feature on Yealink IP phones.
