Install Asterisk 18 / FreePBX 16 on Raspbian Bullseye 64bit/32bit [Raspberry PI 4 aarch64/armhf]

I use this tutorial to setup RemoSIM.com product for customers.

To do:

- Add instructions for enabling fail2ban for asterisk 

- Fix the freepbx startup script issue on boot

I have written about installing Askteris 18 / Free PBX 15 on Ubuntu here before. 

A new version of Raspbian OS based on Debian Bullseye is now available 

Here is the gist I use to install FreePBX 16 on Raspbian Bullseye.

SSH to your raspberry: ssh pi@raspberry.IP.Address 

# Disable ipv6 if it is causing problems in your network:

echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf

sysctl -p 

# update packages there 

sudo apt-get update && sudo apt-get dist-upgrade -y

#freepbx installation must be run as root, so login to SSH as root :

sudo passwd

sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config

service sshd restart

# Install required packages
