Installing 3CX on Server Hardware: An Overview

Your team understands how to install a Web server. What comes next with turning this asset into a 3CX bare metal server?

You will need:

  • Linux (e.g. Debian), Windows (Server 2012 or later), or VM
  • Wired connection and user permissions
  • 3CX license key
  • FQDN

Step 1: Decide the Environment

Chose your installation type:

  • Linux
  • Windows
  • VM

A Linux setup will include the necessary updates upon installation. Windows requires a .Net update. And, VM options should use robust platforms like Hyper-V or VMWare.

Step 2: Install 3CX and FQDN

3CX has a free paid option and three license versions. Input the license key when prompted during the 3CX installation.

The FQDN includes the:

  • Hostname
  • Domain name

3CX may use a static or dynamic IP added during its configuration. The 3CX software and FQDN will create the necessary files and DNS changes. Input the HTTP/HTTPS ports when prompted, too.

Other tasks via prompts during the installation include:

  • Extension Digit Length
  • SMTP and contact details
  • Time zone and country info

Step 3: Access the Management Console

You will gain access to the Management Console upon installation. This process includes adding the license information. The install is complete.

Note: It's recommended you dedicate this hardware to a 3CX-only machine.
