8.1 VPN
Virtual Private Network (VPN) is a technology to allow H83 IP phone to create a tunneling connection to a
server and becomes part of
the server’s network. The network transmission of the phone may be routed
through the VPN server.
For some users, especially enterprise users, a VPN connection might be required to be established before
activate a line registration. The phone supports two VPN modes, Layer 2 Transportation Protocol (L2TP) and
OpenVPN.
The VPN connection must be configured and started (or stopped) from the phone web portal.
8.2 L2TP
NOTICE!
The H83 IP phone only supports non-encrypted basic authentication and non-encrypted data
tunneling. For users who need data encryption, please use OpenVPN instead.
To establish a L2TP connection, users should log in to the phone web portal, open page [Network] -> [VPN].
In VPN Mode, check the “Enable VPN” option and select “L2TP”, then fill in the L2TP server address,
Authentication Username, and Authentication Password in the L2TP section. Press “Apply” then the phone
will try to connect to the L2TP server.
When the VPN connection established, the VPN IP Address should be displayed in the VPN status. There
may be some delay of the connection establishment. User may need to refresh the page to update the status.
Once the VPN is configured, the phone will try to connect to the VPN automatically when the phone boots up
every time until user disable it. Sometimes, if the VPN connection does not established immediately, user
may try to reboot the phone and check if VPN connection established after reboot.
