A2BILLING INSTALLATION GUIDE
============================
0. Sypnosis
-----------
A2Billing is a voip billing software licensed under the AGPL 3.
Copyright (C) 2004-2015 - Star2billing S.L. http://www.star2billing.com/
This document focuses on the installation of A2Billing system for the Asterisk
open source PBX. The document covers the installation and basic configuration
of A2Billing. A2billing is an open source implementation of a telecommunication
billing and added value services platform.
A2billing is a LAMP (Linux/Apache/Mysql/PHP) application that interfaces with
Asterisk using both the AMI and AGI interfaces.
This documentation has been tested using Ubuntu 14.04 and Debian 7/8.
1. A2Billing installation guide
-------------------------------
1.1 Important note about distributions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This documentation assumes that you are using a .deb based distro that has used the folder /usr/share/asterisk during packaging. Other distributions use the alternate
folder /var/lib/asterisk. If you compile from source the path by default is /var/lib/asterisk.
The basic assumptions of this documentation is that used pre-packaged software and:
* your apache2 default root folder is /var/www/html
* your asterisk sounds are under /usr/share/asterisk
* your asterisk AGI folder is expected under /usr/share/asterisk
* your apache2 runs as www-data (uid)
* you asterisk runs as asterisk (uid)
* those using subversion to check out the code, can use symbolic links instead of copying the files to the right directories
1.2 Default passwords and access info
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This are the default passwords that you should know about:
* mysql root password (in default system normally is <ENTER>)
* A2Billing default database is mya2billing, user is a2billinguser and password is a2billing
* asterisk manager default information is: [myasterisk] and secret=mycode
* A2Billing admin default password is: user: root password: changepassword
1.3 Pre-required software packages
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A2billing requires the packages of a LAMP (PHP5) installation. To install
the necessary packages, run the following commands::
apt-get install libapache2-mod-php5 php5 php5-common
apt-get install php5-cli php5-mysql mysql-server apache2 php5-gd
apt-get install openssh-server subversion
A2Billing also requires MCrypt module for PHP5::
apt-get install php5-mcrypt
Asterisk is of course also needed::
Install Asterisk 13 and your depencies like Dahdi and Libpri for Debian 7/8 and Ubuntu Server 14.04 too.
This command is just necessary for Ubuntu Server 14.04 before install Asterisk 13.
apt-get update && apt-get dist-upgrade -y && reboot
Install all dependencies for compile Asterisk
apt-get install build-essential wget libssl-dev libncurses5-dev libnewt-dev libxml2-dev linux-headers-$(uname -r) libsqlite3-dev uuid-dev git-core subversion libjansson-dev sqlite autoconf automake libtool libncurses5-dev vim -y
apt-get autoremove -y && apt-get autoclean -y
cd /usr/src/
wget downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-2.10.2+2.10.2.tar.gz
tar zxvf dahdi-linux-complete*

1.3.1 Extra software to support text-to-speech IVR monitoring
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Since version 1.7 we include an AGI mode that allows the monitoring of
the a2billing system via an IVR.
The monitoring feature requires text-to-speech TTS support, the
default TTS engine is Cepstral (http://www.cepstral.com/) although
A2Billing can support Festival too.
Install Cepstral (default path: /opt/swift) and make a symbolic link::
ln -s /opt/swift/bin/swift /usr/bin/swift
Make sure that the dynamic libraries are linked, create a file called
cepstral.conf under /etc/ld.so.conf.d/ including the path : /opt/swift/lib
1.3 PHP Composer
~~~~~~~~~~~~~~~~
A PHP dependency manager called Composer (https://getcomposer.org/) is used to
install PHP packages needed for A2Billing.
You can follow those steps to install PHP composer::
cd /usr/local/a2billing
curl -sS https://getcomposer.org/installer | php
php composer.phar update
php composer.phar install
2. Installation
---------------
In a nutshell installing A2Billing requires a minimum of seven steps (1-7)
1. Download and unpack source code
2. Setup the database
3. Edit a2billing.conf file. Setting up the database parameters
4. Fix permissions and folders
5. Installing the web based graphical user interfaces (Customer and Admin)
6. Place the AGI files
7. Prepare your dialplan
8. Add your cronjobs (only for notifcations, alarms and recurring services)
9. Configure your callback daemon (only for callback)
10. Enable monitoring (only for IVR monitoring)
11. Enable card locking (only for card PIN locking)
2.1. Step 1: Download and unpack source code
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Create a a2billing folder under /usr/local/src::
mkdir /usr/local/src/a2billing
Unpack the code
Download the code from the GIT repository run: ::
git clone https://github.com/Star2Billing/a2billing.git /usr/local/src/a2billing/ && rm -rf /usr/local/src/a2billing/.git
At the end of this step you should have a a2billing tree structure that should look like::
/usr/local/src/a2billing/
Files::
AGI
CHANGELOG
COPYING
CallBack
Cronjobs : Recurrent services run via crontab
DataBase : Database Schema / DB Installation
FEATURES_LIST
a2billing.conf : Main Configuration file
addons : Sounds and other addons
admin : Admin UI
agent : Agent UI
customer : Customer UI
webservice
2.2. Step 2: Prepare the Database
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We will now create a MySQL database (mya2billing) for the billing software. The file a2billing-createdb-user.sql includes a script that creates the database with the correct access control users and permissions. ::
cd /usr/local/src/a2billing
mysql -u root -p < DataBase/mysql-5.x/a2billing-createdb-user.sql
The script with create a database, username and password with the following default values
- Database name is: mya2billing
- Database user is: a2billinguser
- User password is: a2billing
After creating the database structure, we will create a set of tables and insert some initial basic configuration data::
cd DataBase/mysql-5.x/
./install-db.sh
**Checkpoint 1 :** Check that the database (my2billing) and that (97) tables have been created. ::
mysql -u root -p mya2billing
mysql>show tables
mysql>exit
2.3. Step 3: Edit the a2billing.conf configuration file
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The A2Billing configuration file (a2billing.conf) contains the basic
information to connect to the a2billing database. Copy or make a symbolic
link from /usr/local/src/a2billing/a2billing.conf to /etc/a2billing.conf
a2billing.conf -> /usr/local/src/a2billing/a2billing.conf
Option 1::
cp /usr/local/src/a2billing/a2billing.conf /etc/
Option 2::
ln -s /usr/local/src/a2billing/a2billing.conf /etc/a2billing.conf
Open the file with your favorite text editor (vi is used in this example).
If you are new to Linux, we recommend you to use the text editor Gedit::
vim /etc/a2billing.conf
The only parameters that you need to change here is the database connection
information, an example follows::
[database]
hostname = localhost
port = 3306
user = a2billinguser
password = a2billing
dbname = mya2billing
dbtype = mysql
2.4. Step 4: Fix permissions, files and folders
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In this step, we will tweak the file permissions of Asterisk to fit the A2Billing software. We will also create a number of additional files and folders that A2Billing
needs, which does not come with the default installation.
2.4.1. SIP and IAX
^^^^^^^^^^^^^^^^^^
First we will set a few file permissions (chmod, chown) and create (touch) the SIP and IAX configuration files for Asterisk.::
chmod 777 /etc/asterisk
touch /etc/asterisk/additional_a2billing_iax.conf
touch /etc/asterisk/additional_a2billing_sip.conf
echo \#include additional_a2billing_sip.conf >> /etc/asterisk/sip.conf
echo \#include additional_a2billing_iax.conf >> /etc/asterisk/iax.conf
chown -Rf www-data /etc/asterisk/additional_a2billing_iax.conf
chown -Rf www-data /etc/asterisk/additional_a2billing_sip.conf
2.4.2. Sound files
^^^^^^^^^^^^^^^^^^
Run the sounds installation script available in the addons folder (IMPORTANT: the script assumes that asterisk sounds are under /usr/share/asterisk/sounds/)::
/usr/local/src/a2billing/addons/install_a2b_sounds_deb.sh
chown -R asterisk:asterisk /usr/share/asterisk/sounds/
2.4.3. Configure Asterisk Manager
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Configure the Asterisk Manager by editing the manager.conf file::
vim /etc/asterisk/manager.conf
Notice that we are using the default values (myasterisk, mycode) in this section. The configuration should look like this::
[general]
enabled = yes
port = 5038
bindaddr = 0.0.0.0
[myasterisk]
secret=mycode
read=system,call,log,verbose,command,agent,user
write=system,call,log,verbose,command,agent,user
2.5. Step 6: Install The AGI components
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Copy or create a symbolic link of the entire content of the AGI directory into asterisk agi-bin directory::
mkdir /usr/share/asterisk/agi-bin
chown asterisk:asterisk /usr/share/asterisk/agi-bin
Option 1::
cd /usr/local/src/a2billing/AGI
cp a2billing.php /usr/share/asterisk/agi-bin/
cp a2billing-monitoring.php /usr/share/asterisk/agi-bin/
cp -Rf ../common/lib /usr/share/asterisk/agi-bin/
Option 2::
ln -s /usr/local/src/a2billing/AGI/a2billing.php /usr/share/asterisk/agi-bin/a2billing.php
ln -s /usr/local/src/a2billing/AGI/lib /usr/share/asterisk/agi-bin/lib
Make sure the scripts are executable::
chmod +x /usr/share/asterisk/agi-bin/a2billing.php
(if you are going to run the monitoring AGI script)::
chmod +x /usr/share/asterisk/agi-bin/a2billing_monitoring.php
2.6. Step 5: Install web-based Graphical interfaces
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In this step, we will install the three graphical interfaces of A2Billing:
the Administration (admin), Agent (agent) and Customer (customer) interface.
As in previous steps you can copy the folders of make symbolic links.
Place the directories "admin" and "customer" into your webserver document root.
Create a2billing folder in your web root folder::
mkdir /var/www/html/a2billing
chown www-data:www-data /var/www/html/a2billing
Create folder directory for monitoring Scripts::
mkdir -p /var/lib/a2billing/script
Create folder directory for Cronts PID::
mkdir -p /var/run/a2billing
Option 1::
cp -rf /usr/local/src/a2billing/admin /var/www/html/a2billing
cp -rf /usr/local/src/a2billing/agent /var/www/html/a2billing
cp -rf /usr/local/src/a2billing/customer /var/www/html/a2billing
cp -rf /usr/local/src/a2billing/common /var/www/html/a2billing
cp -rf /usr/local/src/a2billing/vendor /var/www/html/a2billing/vendor
Option 2::
ln -s /usr/local/src/a2billing/admin /var/www/html/a2billing/admin
ln -s /usr/local/src/a2billing/agent /var/www/html/a2billing/agent
ln -s /usr/local/src/a2billing/customer /var/www/html/a2billing/customer
ln -s /usr/local/src/a2billing/common /var/www/html/a2billing/common
ln -s /usr/local/src/a2billing/vendor /var/www/html/a2billing/vendor
Fix the permissions of the templates_c folder in each of the UI::
chmod 755 /usr/local/src/a2billing/admin/templates_c
chmod 755 /usr/local/src/a2billing/customer/templates_c
chmod 755 /usr/local/src/a2billing/agent/templates_c
chown -Rf www-data:www-data /usr/local/src/a2billing/admin/templates_c
chown -Rf www-data:www-data /usr/local/src/a2billing/customer/templates_c
chown -Rf www-data:www-data /usr/local/src/a2billing/agent/templates_c
Checkpoint 2: Direct a browser to the administrative web interface (http://<ip-addr>/a2billing/admin) and login as administrator. Default passwords are:
- user: root
- pass: changepassword
2.7. Step 7: Create a dialplan for A2Billing
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The extensions.conf is the Asterisk dialplan. Calls that interact with the billing software need to be handled inside of one or many A2Billing related contexts.
The calls that reach the context are processed using the a2billing.php AGI script. The a2billing.php script can be invoked in many different modes (standard, did,voucher, callback, etc). In the example, we create two different contexts, the first context [a2billing] handles all the calls from our VoIP clients. When a call arrives, any extension number _X. (2 digits or more) reaches the script a2billing.php
The second context [did], will be used to route inward calls back to the users. Calls to the clients (DID) are handled inside of the [did] context. The script a2billing.php in did mode is responsible of routing the call back to one of our users.
Edit extension.conf::
vim /etc/asterisk/extensions.conf
and the following contexts::
[a2billing]
include => a2billing_callingcard
include => a2billing_monitoring
include => a2billing_voucher
[a2billing_callingcard]
; CallingCard application
exten => _X.,1,NoOp(A2Billing Start)
exten => _X.,n,DeadAgi(a2billing.php|1)
exten => _X.,n,Hangup
[a2billing_voucher]
exten => _X.,1,Answer(1)
exten => _X.,n,DeadAgi(a2billing.php|1|voucher)
;exten => _X.,n,AGI(a2billing.php|1|voucher44) ; will add 44 in front of the callerID for the CID authentication
exten => _X.,n,Hangup
[a2billing_did]
exten => _X.,1,DeadAgi(a2billing.php|1|did)
exten => _X.,2,Hangup
Note that newer versions of Asterisk use a comma (,) instead of a pipe (|) to separate the AGI arguments.
2.8. Step 8: Configure recurring services
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Recurring services are handled via the /etc/crontab
You can add the following cron jobs to your /etc/crontab or create a file with
the jobs in /var/spool/cron/a2billing
- update the currency table::
0 6 * * * php /usr/local/src/a2billing/Cronjobs/currencies_update_yahoo.php
- manage the monthly services subscription::
0 6 1 * * php /usr/local/src/a2billing/Cronjobs/a2billing_subscription_fee.php
- To check account of each Users and send an email if the balance is less than the user have choice::
0 * * * * php /usr/local/src/a2billing/Cronjobs/a2billing_notify_account.php
- This script will browse all the DID that are reserve and check if the customer
need to pay for it bill them or warn them per email to know if they want to pay
in order to keep their DIDs::
0 2 * * * php /usr/local/src/a2billing/Cronjobs/a2billing_bill_diduse.php
- This script will take care of the recurring service. ::
0 12 * * * php /usr/local/src/a2billing/Cronjobs/a2billing_batch_process.php
- Generate Invoices at 6am everyday::
0 6 * * * php /usr/local/src/a2billing/Cronjobs/a2billing_batch_billing.php
- to proceed the autodialer::
* / 5 * * * * php /usr/local/src/a2billing/Cronjobs/a2billing_batch_autodialer.php
- manage alarms::
0 * * * * php /usr/local/src/a2billing/Cronjobs/a2billing_alarm.php
2.9. Step 9: Call back daemon (only for Call backs)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The call back daemon is responsible of reading from the database the pool of
calls stored for call back and trigger those calls periodically.
The daemon is written in Python. Install the python-setuptools and use
easy_install to install the callback_daemon::
apt-get install python-setuptools python-mysqldb python-psycopg2 python-sqlalchemy
cd /usr/local/src/a2billing/CallBack
easy_install callback-daemon-py/dist/callback_daemon-1.0.prod_r1527-py2.5.egg
Install the init.d startup script::
cd /usr/local/src/a2billing/CallBack/callback-daemon-py/callback_daemon/
For Debian::
cp a2b-callback-daemon.debian /etc/init.d/a2b-callback-daemon
For RedHat::
cp a2b-callback-daemon.rc /etc/init.d/a2b-callback-daemon
chmod +x /etc/init.d/a2b-callback-daemon
Make sure the daemon starts,
For Debian::
update-rc.d a2b-callback-daemon defaults 40 60
If you need to remove the daemon in the future run::
update-rc.d -f a2b-callback-daemon remove
For RedHat::
chkconfig --add a2b-callback-daemon
service a2b-callback-daemon start
chkconfig a2b-callback-daemon on
2.10. Step 10: Enable IVR monitoring
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
General system monitoring via IVR is available from version 1.7, the new AGI
a2billing_monitoring.php provides access to an IVR where monitoring tasks can be
configured via the new Monitoring Menu under Maintenance.
SQL queries can be performed and shell scripts can be invoked.
Place your scripts under /var/lib/a2billing/script/
2.11. Step 11: Security features via IVR (Monitor account and locking calling card)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Two new IVR menus are now available via the main a2billing.php AGI. The menus
needs to be enabled setting the variables in the agi-conf menu (GUI system settings)
Locking Options IVR menu::
ivr_enable_locking_option = true (default: false)
Monitoring your Calling Card IVR menu::
ivr_enable_account_information = true (default: false)
