VOIP PABX on A Raspberry Pi 5

Install PiOs Lite 64 Bit

Select your Pi
And PiOS 64-bit Lite
And your memory card
Ensure that you set the hostname, enable ssh and set the username to something obscure

Select 'Write' and wait ....

Once installed, boot your Pi using the memory card - it will reboot as part of this sequence, but eventually you will be able to connect to is via ssh

Login and Run Screen

# ssh -l obscureadmin pi-name.local

# sudo apt-get install screen

# screen

Install MySQL and Sendmail

# apt install mariadb-server

# apt install sendmail

Install php 7.4 (php8.2 does not work)

# sudo apt -y install lsb-release apt-transport-https ca-certificates

# sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg

# tc/apt/sources.list.d/php.list

# apt install php7.4 php7.4-xml php7.4-mysql php7.4-mbstring

Install a few useful pre-requisites

# sudo apt install sox mpg123

Download and unpack Pi5 Installer script

# wget http://incrediblepbx.com/IncrediblePBX2027-D-RasPi.sh

# chmod a+x IncrediblePBX2027-D-RasPi.sh

# ./IncrediblePBX2027-D-RasPi.sh | tee incrediblepbx.log

And Wait for an hour or two, and reboot when prompted

Check Everything is Installed

# /root/pbxstatus-U

Notes

If you don't install php7.4 and attempt to install with version 8.2, for example - you will get problems in astrisk, for example no support for 'res_pjsip_config_sangoma'; and freepbx will fail to install properly.

----

Modify and Complete Failed Asterisk Installation

# (cd /usr/src/asterisk* ; make menuselect) # and uncheck 'res_pjsip_config_sangoma' - at the bottom of the resources list

# (cd /usr/src/asterisk* ; make install)

# systemctl enable asterisk

# systemctl start asterisk

possibly - chgrp www-data /etc/freepbx.conf

Complete Broken Freepbx Installation

# (cd /usr/src/freepbx ; ./install)

------------------------------

Edit /var/www/html/admin/libraries/utility.functions.php

and Modify Line 306 as follows:

function freepbx_error_handler($errno, $errstr, $errfile, $errline, $errcontext = 'undefined') {

The above sequence has the following shortfalls:

The existing menuselect.makeopts file did not specify

that 'res_pjsip_stir_shaken', 'res_stir_shaken', 'test_aeap', 'test_aeap_speech', 'test_aeap_transaction', 'test_aeap_transport', 'test_capture', 'test_crypto' should not be included. However,

dependencies for this module were not found.

Either run 'make menuselect' or remove the existing

menuselect.makeopts file to resolve this issue.
