NOTE: To use OpenVPN functionalities, users must enable OpenVPN and configure all of the settings
related to OpenVPN, including server address, port, OpenVPN CA, certificate and key. Additionally, the
user must also set the SIP account to use "VPN" for the "Nat Traversal" (under Account-> Network
Settings). Reboot the phone after these settings are saved for the changes to take effect. Once the phone
connects to the OpenVPN server and the authentication is correct, the phone will show the VPN IP
address under the Status-> Network Status, but it will still display the LAN IP on the LCD of the phone.
