Description

Enables or disables the phone to connect using the OpenVPN client.

If VPN is enabled, but not connected, all SIP traffic will continue to route via the LAN IP.
If VPN is enabled and connected, all SIP traffic will route via the VPN tunnel. The exception is the web server, which will still be accessible via the LAN IP.

Configuring VPN using the WebUI consists of enabling VPN and uploading a VPN configuration file. The VPN configuration file (openvpn_client.tar) must contain the following files:

  • client.conf
  • a keys folder containing
    • ca.crt
    • client.crt
    • client.key

The filename of the VPN client configuration file and certificates must match the names provided above. 
Ensure that NTP or manual time is configured correctly so that the phone is using the correct date and time before VPN setup. Mismatched time between sites and servers may invalidate the initial TLS handshake.

On the WebUI, go to: Network → Advanced → VPN → VPN Config (file upload). Browse to and upload the VPN configuration file openvpn_client.tar.
