How to install VPN on IP PBX server?
Connecting extensions to a PBX server via VPN is a secure way to ensure that the communication between the extensions and the PBX server is encrypted and protected from external attacks.
Here are the general steps to connect extensions to a PBX server via VPN:
Set up the VPN server: Install and configure the VPN server on a separate server or device. The server should be connected to the internet and have a public IP address.
Configure the VPN client: Configure the VPN client on each extension device or softphone. The client should be configured to connect to the VPN server using the appropriate settings.
Configure the PBX server: Configure the PBX server to accept connections from the VPN network. This can usually be done by configuring the firewall rules and NAT settings.
Connect to the VPN: Connect each extension device or softphone to the VPN network using the VPN client.
Configure the extensions: Configure the extensions on the PBX server to use the VPN IP address as their SIP server address.
By following these steps, you can securely connect extensions to a PBX server via VPN, ensuring that the communication between the extensions and the PBX server is encrypted and protected from external attacks.
