5.2 Configure your phone for remote working
Your IP phone is compatible with remote working (VPN) via a secure connection (encrypted). A
Virtual Private Network (VPN) is a technology that allows a device to create a tunneling connection
to a server and becomes part of the enterprise’s network (VPN server’s network). VPN tunnels are
secured with OpenVPN protocol with TLS authentication, credentials and certificates.
To establish an VPN connection, make sure you have information about connection from the
hosting provider:
Connection settings: server address, port and protocol.
CA root certification file (.crt).
Client certification file (.crt).
Client key file (.key).
The VPN connection must be configured, started and stopped from the Web Management device.
Open the Web Management device.
When the phone is connected to the network, your administrator can access the Web
Management via a web browser by entering the IP address of your phone. The
administrator password of the phone is requested.
In the settings tab, select the VPN menu (OpenVPN).
Enter the required information (VPN server address, port and protocol).
Upload security files: choose a file and select the upload button for each file (CA root
certification, Client certification, Client key file).
Enable VPN.
Apply.
The desk phone restarts.
