MongoDB

Only required if you plan to use XMPP

echo "deb http://repo.mongodb.org/apt/debian $(lsb_release -sc)/mongodb-org/4.2 main" \
| sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list

apt update && apt install -y mongodb-org

systemctl enable mongod

Libjansson

Asterisk v16 requires libjansson >= 2.11.   

# Mandatory for Debian v9.  Optional for Debian v10 which includes a new enough version.

cd /usr/src
wget http://www.digip.org/jansson/releases/jansson-2.12.tar.gz
tar -zxvf jansson-2.12.tar.gz
cd jansson-2.12/
./configure && make && make install

Set Timezone

## FIND YOUR TIMEZONE
tzselect
## SET TIMEZONE EXAMPLE
timedatectl set-timezone America/Vancouver
timedatectl status
systemctl restart rsyslog

Install

DAHDI

Only required if using a physical server and installing telecom hardware.  At this time, versions newer than 2.10.2 (2.11.0 and 2.11.1) do not install correctly.

cd /usr/src
wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-2.10.2+2.10.2.tar.gz
tar zxvf dahdi-linux-complete-2.10*
cd /usr/src/dahdi-linux-complete-2.10*/
make all && make install && make config
systemctl restart dahdi

If make all fails try reboot and run apt install linux-headers*

Asterisk

If upgrading an existing install with older Asterisk, it is best to run  rm -rf /usr/lib/asterisk/modules first.

cd /usr/src
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-16-current.tar.gz
tar zxvf asterisk-16-current.tar.gz
cd /usr/src/asterisk-16*/
make distclean

Install additional dependencies

cd /usr/src/asterisk-16*/
./contrib/scripts/install_prereq install

Configure

cd /usr/src/asterisk-16*/
./configure --with-pjproject-bundled --with-jansson-bundle

To verify type nano -v config.log.

Set compile options

cd /usr/src/asterisk-16*/
make menuselect

# Go to Applications and make sure app_macro is checked.
# To change compile options after install simply run make menuselect and make && make install again.

Create Asterisk User, compile, install and set preliminary ownership.

adduser asterisk --disabled-password --gecos "Asterisk User"
make && make install && chown -R asterisk. /var/lib/asterisk

Freepbx

cd /usr/src
git clone -b release/15.0 --single-branch https://github.com/freepbx/framework.git freepbx
touch /etc/asterisk/modules.conf
cd /usr/src/freepbx
./start_asterisk start

./install -n
# Minimal module install
fwconsole ma downloadinstall framework core voicemail sipsettings infoservices \
featurecodeadmin logfiles callrecording cdr dashboard music soundlang recordings conferences
fwconsole chown
fwconsole reload

Optionally, install all modules (not recommended).  You may need to run the following commands twice.

fwconsole ma installall
fwconsole chown
fwconsole reload

Set Freepbx to start on boot

cat >> /etc/systemd/system/freepbx.service << EOF
[Unit]
Description=Freepbx
After=mariadb.service
 
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/sbin/fwconsole start
ExecStop=/usr/sbin/fwconsole stop
 
[Install]
WantedBy=multi-user.target

EOF
systemctl enable freepbx

Configure Apache

Add AllowOverride All to web directory so that .htaccess is active.

cat >> /etc/apache2/conf-available/allowoverride.conf << EOF 
<Directory /var/www/html>
    AllowOverride All
    </Directory>
EOF
a2enconf allowoverride

Change default apache user/group, disable index.html, enable rewrite module

sed -i 's/\(APACHE_RUN_USER=\)\(.*\)/\1asterisk/g' /etc/apache2/envvars
sed -i 's/\(APACHE_RUN_GROUP=\)\(.*\)/\1asterisk/g' /etc/apache2/envvars
chown asterisk. /run/lock/apache2
mv /var/www/html/index.html /var/www/html/index.html.disable
a2enmod rewrite
systemctl restart apache2

Reboot and access GUI

reboot

You should now be able to access the Freepbx GUI at http://yourserverIP

Post-install tasks are mandatory.

Post-install tasks

Lock down the database server.

mysql_secure_installation

Answer Y to everything.

Log File Rotation

If this is not done the log files will keep growing indefinitely.

nano /etc/logrotate.d/asterisk
/var/spool/mail/asterisk
/var/log/asterisk/full
/var/log/asterisk/dtmf
/var/log/asterisk/fail2ban
/var/log/asterisk/freepbx.log
/var/log/asterisk/freepbx_security.log 
/var/log/asterisk/freepbx_debug {
        weekly
        missingok
        rotate 4
        #compress
        notifempty
        sharedscripts
        create 0640 asterisk asterisk
        postrotate
        /usr/sbin/asterisk -rx 'logger reload' > /dev/null 2> /dev/null || true
        endscript
        su root root
}

Test ODBC

odbcinst -s -q

Use username & password in /etc/asterisk/res_odbc_additional.conf to test connectivity to the DB via ODBC. 

isql -v MySQL-asteriskcdrdb someusername somepassword

Test asterisk ODBC access

asterisk -vvvr
CLI> odbc show

TFTP

If you plan to use hardware SIP phones you will probably want to enable the tftp server.

Create tftp configuration file.

nano /etc/xinetd.d/tftp
service tftp
{
protocol        = udp
port            = 69
socket_type     = dgram
wait            = yes
user            = nobody
server          = /usr/sbin/in.tftpd
server_args     = /tftpboot
disable         = no
}

Make the directory and restart the daemon to start tftp.

mkdir /tftpboot
chmod 777 /tftpboot
systemctl restart xinetd

Misc. settings

Set php memory limit and upload max file size.

sed -i 's/memory_limit = .*/memory_limit = 256M/g' /etc/php/7.3/apache2/php.ini
sed -i 's/upload_max_filesize = .*/upload_max_filesize = 20M/g' /etc/php/7.3/apache2/php.ini
systemctl restart apache2

Troubleshooting

As the moment there is a bug in Freepbx related to Debian/Ubuntu.  If pressing the Apply Config button on the GUI hangs try the following as a temporary work around.

apt purge dirmngr
killall -p dirmngr
