Install 3CX PBX on Debian 10/9/8 manually
Step 1: Update your system packages
Let’s make sure we have all packages updated.

sudo apt update
sudo apt upgrade -y
If you have Kernel updates, it is recommended to reboot your server before you continue with the installation.

[ -f /var/run/reboot-required ] && sudo reboot -f
Step 2: Add 3CX Repository to Debian 10/9/8
Next is to add the 3CX packages repository to your system. Start by importing GPG key used for signing packages.

wget -O- http://downloads-global.3cx.com/downloads/3cxpbx/public.key | sudo apt-key add -
Once the key is imported, add repository

# Add repository to Debian 10
sudo apt install gnupg2 -y
echo "deb http://downloads-global.3cx.com/downloads/debian buster main" | sudo tee /etc/apt/sources.list.d/3cxpbx.list

# Add repository to Debian 9
sudo apt install gnupg2 -y
echo "deb http://downloads-global.3cx.com/downloads/debian stretch main" | sudo tee /etc/apt/sources.list.d/3cxpbx.list

# Add repository to Debian 8
sudo apt install gnupg2 -y
echo "deb http://downloads.3cx.com/downloads/debian jessie main" | sudo tee /etc/apt/sources.list.d/3cxpbx.list
