Introduction

This howto is written for ubuntu 14.04 LTS server. You can use the same commands for debian based servers, but depending on version, some commands may differ.

Prerequisites

First, you need to install these packages :

apt-get install git-core build-essential autoconf automake libtool libncurses5 libncurses5-dev gawk libjpeg-dev zlib1g-dev pkg-config libssl-dev libpq-dev unixodbc-dev odbc-postgresql postgresql postgresql-client libpq-dev libxml2-dev libxslt-dev ntp ntpdate libapache2-mod-wsgi apache2 gcc python-setuptools python-pip libjpeg62 libjpeg62-dev libdbd-pg-perl libtext-csv-perl sqlite3 libsqlite3-dev libcurl4-openssl-dev libpcre3-dev libspeex-dev libspeexdsp-dev libldns-dev libedit-dev libmemcached-dev python-psycopg2 python-dev libgeoip-dev

Freeswitch installation

go to the source directory :

cd /usr/src

and download the last stable freeswitch version

git clone -b v1.4 https://stash.freeswitch.org/scm/fs/freeswitch.git

after, boostrap, configure, make and install freeswitch

cd freeswitch
./bootstrap.sh -j

edit modules.conf suiting your needs. You will find below the minimum list of modules to be installed :

applications/mod_commands
applications/mod_db
applications/mod_dptools
pplications/mod_esf
applications/mod_esl
applications/mod_expr
applications/mod_fifo
applications/mod_fsv
applications/mod_hash
applications/mod_memcache
applications/mod_nibblebill
codecs/mod_amr
codecs/mod_g723_1
codecs/mod_spandsp
codecs/mod_siren
codecs/mod_amrwb
codecs/mod_g729
dialplans/mod_dialplan_xml
endpoints/mod_loopback
endpoints/mod_sofia
event_handlers/mod_cdr_csv
event_handlers/mod_event_socket
formats/mod_local_stream
formats/mod_native_file
formats/mod_sndfile
formats/mod_tone_stream
languages/mod_lua
languages/mod_spidermonkey
loggers/mod_console
loggers/mod_logfile
loggers/mod_syslog
say/mod_say_en

after, do :

./configure
make
make install

you need to compile esl for python

cd libs/esl
make pymod
make pymod-install

create a freeswitch user and group as follow :

groupadd freeswitch
adduser --disabled-password --quiet --system --home /usr/local/freeswitch --gecos "FreeSWITCH Voice Platform" --ingroup daemon freeswitch

and to apply the rule to freeswitch user :

chown -R freeswitch:daemon /usr/local/freeswitch/
chmod -R ug=rwX,o= /usr/local/freeswitch/
chmod -R u=rwx,g=rx /usr/local/freeswitch/bin/

and now, we need to create the init script to start and stop
freeswitch :

nano /etc/init.d/freeswitch

Add your init code

#!/bin/bash

make this script executable :

chmod +x /etc/init.d/freeswitch
update-rc.d freeswitch defaults

add the cli link :

ln -s /usr/local/freeswitch/bin/fs_cli /bin/fs_cli

Postgresql configuration

create user and database :

sudo -i -u postgres
createuser -P pyfreebilling
Enter password for new role:
Enter it again:
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) y
Shall the new role be allowed to create more new roles? (y/n) y
createdb -O pyfreebilling -E UTF8 pyfreebilling
exit

set odbc parameters; you need to create and edit /etc/odbc.ini file. Do not forget to specify your postgres password !

Web server install

securing apache

sudo a2enmod ssl
sudo make-ssl-cert /usr/share/ssl-cert/ssleay.cnf /etc/ssl/private/localhost.pem (or use others methods or certificats)

install python virtualenv

pip install virtualenv
cd /usr/local
virtualenv venv --no-site-packages
chown -R myuser:mysuser venv (replace myuser by your current user, perhaps root - better other one)

activate it :

source venv/bin/activate
cd venv

install CPAN

install all dependent packages for CPAN

apt-get install build-essential

invoke the cpan command as a normal user :

$cpan
But once you hit on enter for “cpan” to execute, you be asked of
some few questions. To make it simple for yourself, answer “no”
for the first question so that the latter ones will be done for
you automatically.
->; ANSWER YES

Once the above is done, you will be present with the cpan prompt.
now enter the commands below

cpan prompt>; make install
cpan prompt>; install Bundle::CPAN

Now all is set and you can install any perl module you want.
examples of what installed below

cpan prompt>; install Carp
cpan prompt>; install Filter::Simple
cpan prompt>; install Config::Vars
cpan prompt>; exit

Pyfreebilling installation

download pyfreebilling sources :

git clone https://github.com/mwolff44/pyfreebilling.git
chown -R www-data:www-data pyfreebilling
cd pyfreebilling

create un new file in pyfreebilling directory called local_settings.py

touch pyfreebilling/local_settings.py

edit this new file, and put yours specific values

# -*- coding: utf-8 -*-
from .settings import *

DEBUG = False

MANAGERS = ADMINS

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'pyfreebilling',
'USER': 'pyfreebilling',
'PASSWORD': 'password',
'HOST': '127.0.0.1',
'PORT': '', # Set to empty string for default.
}
}

ALLOWED_HOSTS = ['*']

SECRET_KEY = 'securitykeymustbechanged' # very important - put your key for security - any string

TIME_ZONE = 'Europe/Paris'

OPENEXCHANGERATES_APP_ID = "Your API Key"

#-- Nb days of CDR to show
PFB_NB_ADMIN_CDR = 3
PFB_NB_CUST_CDR = 30

# EMAIL SETUP
TEMPLATED_EMAIL_BACKEND = 'templated_email.backends.vanilla_django.TemplateBackend'
TEMPLATED_EMAIL_TEMPLATE_DIR = 'templated_email/'
TEMPLATED_EMAIL_FILE_EXTENSION = 'email'

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = ''
EMAIL_PORT = 587
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
#EMAIL_USE_TLS = True
EMAIL_USE_SSL = True
EMAIL_SIGNATURE = ''

and now, enter the following commands without sudo (IMPORTANT). At the step “syncdb”, you will fave a prompt asking you to enter a username and a password. They are very important, as thez are the admin one !

pip install -r requirements/requirements.txt
python manage.py syncdb (IMPORTANT : enter your username and password)
python manage.py initcurrencies
python manage.py migrate
python manage.py loaddata country_dialcode.json
python manage.py loaddata switch 0001_fixtures.json
python manage.py loaddata 0001_initial_SipProfile.json
python manage.py loaddata 0001_initial_ReccurentTasks.json
python manage.py loaddata country.json
python manage.py updatecurrencies (if you have set your Openexchange API key)
python manage.py collectstatic (answer 'yes')

Pyfreebilling login

Got to the url https://my-ip/extranet and enter your username and password.
The customer portal url is : https://my-ip

I recommend to setup a firewall restrincting access to web pages and your voip ports !
