If you are also facing the same issue of installing 3CX Phone System on your cloud, let’s see what to do.
Prerequisite for 3CX Phone System
A cloud instance with Debian ISO installed on it. We will be trying Debian Linux 10.
Adding the repository
Run the commands below as the root user:
apt install gnupg
wget -O- http://downloads-global.3cx.com/downloads/3cxpbx/public.key | apt-key add -
echo "deb http://downloads-global.3cx.com/downloads/debian buster main" | tee /etc/apt/sources.list.d/3cxpbx.list
apt update && apt install net-tools dphys-swapfile htop mtr screen curl dnsutils -y
Commands for installing 3CX
apt install 3cxpbx -y
Start the installation
The installation already began with the previous command apt install 3cxpbx -y. When asked, Press Tab to select the <Ok> button and press Enter to accept the 3cx license agreement.
Finish the Installation of 3CX Phone System
When the installation is finished, you will see the following screen, which asks you to select the configuration option. I’d recommend typing 1 (which selects Using a Web Browser) and hitting Enter, which will show you the URL to configure 3CX Phone System.
