A2Billing v2 Install Guide

This guide will show how to install A2Billing v2.x on a Redhat Enterprise Linux v6 based system.  It is assumed you already have Linux and Asterisk and FreePBX installed using a procedure similar to this one.  It is also assumed you have compiled asterisk realtime driver module (res_config_mysql) by selecting it in asterisk menuselect before compiling asterisk. We do not cover the installation of the callback daemon.

Tested using the following software:

The following 2 diagrams illustrate A2billing inbound and outbound call flow.

All commands are assuming you are at run level 3 running in a shell as root.  In other words, not in a Gnome/KDE GUI and not using a limited access account.

Install EPEL repo

If not already done so.
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
yum update

Install additional required packages if not already installed

yum -y install php-mcrypt perl-DBD-Pg
Get A2Billing source
cd /usr/src
wget --no-check-certificate https://github.com/Star2Billing/a2billing/tarball/v2.0.5 -O Star2Billing.tar.gz
tar zxvf Star2Billing.tar.gz

Rename the directory

mv Star2Billing* a2billing

Create MySQL root password

If you did not create a mysql root password during the asterisk install you should create one now.
mysqladmin -u root password 'rootmysqlpassword'

If MySQL root password already exists

If you get access denied the password has already been set.  For PowerPBX install guide a password of abcdef was used.  For distributions such as PiaF, the password might be passw0rd.  This will be the password the following commands will ask for.

If you do not know the MySQL root password and want to change it

If you do not know what it is this guide has a procedure for changing the MySQL root password which is as follows.  Otherwise skip down to Create A2Billing Database.
#service mysqld stop
# mysqld_safe --skip-grant-tables &
If you don't see a command prompt (#) appear press the ENTER key and you should get it.
mysql --user=root mysql
update user set Password=PASSWORD('new-root-password') where user='root';
>\q
service mysqld restart

Create A2Billing Database

cd /usr/src/a2billing
mysql -u root -p < DataBase/mysql-5.x/a2billing-createdb-user.sql
which, after you enter your root password, will create:
Database name: mya2billing
Database user: a2billinguser
Database user password: a2billing
Now run script to create tables and insert some basic configuration data
cd /usr/src/a2billing/DataBase/mysql-5.x
./install-db.sh
Answer questions as follows:
  • Enter Database Name: mya2billing
  • Enter Hostname: localhost
  • Enter UserName: root
  • Enter Password: {mysql-root-password...not a2billing db password}
Now check that the database and 90+ tables have been created
mysql -u root -p mya2billing
>show tables;
Should produce
+-------------------------+
| Tables_in_mya2billing    
| +-----------------------+
| cc_agent                |
| cc_agent_commission     |
| cc_agent_signup         |
. . .                     |
| cc_ui_authen            |
| cc_version              |
| cc_voucher              |
+-------------------------+
97 rows in set (0.00 sec)
\q
cp /usr/src/a2billing/a2billing.conf /etc/
Make sure the following parameters are set as shown.
nano /etc/a2billing.conf
[database]
hostname = localhost
port = 3306
user = a2billinguser
password = a2billing
dbname = mya2billing
dbtype = mysql

Create files and set permissions

Only required if not using Asterisk Realtime.  If unsure then proceed as if you are not using Asterisk Realtime.  Some of these files assume you have FreePBX installed and not just Asterisk.  If you just have Asterisk installed then use the files specified in the INSTALL.rst instructions included with A2billing source files.
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_custom.conf
echo \#include additional_a2billing_iax.conf >> /etc/asterisk/iax_custom.conf
chown -Rf asterisk:asterisk /etc/asterisk/additional_a2billing_iax.conf
chown -Rf asterisk:asterisk /etc/asterisk/additional_a2billing_sip.conf

Run sound installation script

cd /usr/src/a2billing/addons/sounds
./install_a2b_sounds.sh
chown -R asterisk:asterisk /var/lib/asterisk/sounds/

Add the following to /etc/asterisk/manager_custom.conf

You can also do it via the FreePBX Asterisk API module.  If you don't have FreePBX installed then you should follow the INSTALL.rst instructions included with the a2billing source files.
[myasterisk]
secret=mycode
deny=0.0.0.0/0.0.0.0
permit=127.0.0.1/255.255.255.0
read=system,call,log,verbose,command,agent,user
write=system,call,log,verbose,command,agent,user

Set up a2billing web folders

A2billing has 3 GUIs.  admin, agent, and customer.
mkdir /var/www/html/a2billing
Directory may already exist.
cp -rf /usr/src/a2billing/admin /var/www/html/a2billing
cp -rf /usr/src/a2billing/agent /var/www/html/a2billing
cp -rf /usr/src/a2billing/customer /var/www/html/a2billing
cp -rf /usr/src/a2billing/common /var/www/html/a2billing
chown -R asterisk:asterisk /var/www/html/a2billing
chmod 755 /var/www/html/a2billing/admin/templates_c
chmod 755 /var/www/html/a2billing/customer/templates_c
chmod 755 /var/www/html/a2billing/agent/templates_c

Check admin web interface

From a web browser go to (http://{my-ip-address}/a2billing/admin) and make sure you get the authentication screen.  Log in as follows.
user: root
password: changepassword
Once logged in click change password link at bottom left and change it.

Set up AGI

mkdir /var/lib/asterisk/agi-bin
cd /usr/src/a2billing/AGI               
cp a2billing.php /var/lib/asterisk/agi-bin
cp a2billing_monitoring.php /var/lib/asterisk/agi-bin
chown -R asterisk:asterisk /var/lib/asterisk/agi-bin
chmod 755 /var/lib/asterisk/agi-bin/a2billing.php
chmod 755 /var/lib/asterisk/agi-bin/a2billing_monitoring.php
ln -s /var/www/html/a2billing/common/lib /var/lib/asterisk/agi-bin/lib

Add the following extensions to /etc/asterisk/extensions_custom.conf

If not using FreePBX then this would go into /etc/asterisk/extensions.conf.  These are just examples.  Depending on what you are doing and how you are doing it some may not apply and some may not work.  Customizing this to your needs is considered beyond the scope of this document.  Search for documentation on Asterisk custom extensions and dialplans.  If possible try find examples specific to A2Billing.
nano /etc/asterisk/extensions_custom.conf
[macro-dialout-trunk-predial-hook]

Go into FreePBX GUI>Setup>Trunks>Add Custom Trunk give it a name and add the following dial string:

A2B/1
This is the trunk that is used to send calls out via A2Billing.  Simply select this trunk in outbound routes.  The /1 refers to which agi-conf is going to be used in /etc/a2billing.conf.

Add custom destinations to FreePBX via FreePBX GUI>Tools>Custom Destinations

These destinations are referring to the custom extensions created above in /etc/asterisk/extensions_custom.conf

Start or restart FreePBX
amportal restart

Recurring Services

Recurring services are handled via the /etc/crontab. Make directory for A2Billing cron PID
mkdir -p /var/run/a2billing
chown asterisk:asterisk /var/run/a2billing

Copy cron files to some permanent location such as /usr/local

mkdir -p /usr/local/a2billing
cp -R /usr/src/a2billing/Cronjobs /usr/local/a2billing/
ln -sf /var/www/html/a2billing/common/lib /usr/local/a2billing/Cronjobs/lib
chown -R asterisk:asterisk /usr/local/a2billing

Add the cron jobs to /var/spool/cron/asterisk

touch /var/log/a2billing/a2billing_agi.log
chown -R asterisk:asterisk /var/log/a2billing

Add index file to prevent browsing of root folder

touch /var/www/html/a2billing/index.html

Log into the webpage

http://{my-ip-address}/a2billing/admin
  • user:  root
  • pass: mynewpassword
Or use default password changepassword if you have not changed it yet and then click the change password link at the bottom left.

Set Asterisk version in A2Billing

Go into System settings>Global list.  Go to the bottom left and set to display all.  From your web browser search for "asterisk_version".  It will find that setting twice.  One for Global group and one for agi-conf1 group.  Change both accordingly.  If using Asterisk v11 then use "1_11" Disable Asterisk Realtime if not setting up the following Asterisk Realtime procedure Go to System settings>Global search for "realtime".  Change that setting to "no".

Asterisk Realtime

It may be beneficial to use Asterisk Realtime with A2billing.  If running Asterisk Realtime you do not need to reload every time you add/remove/change a customer.  Also it allows you to share the A2billing database between multiple Aserisk/FreePBX servers if you needed to do that.  If you need to create many customers it makes more sense to use a database instead of putting them all in a flat text file. Double check you have the Asterisk Realtime module installed.  If using 64bit OS the modules are in /usr/lib64/asterisk/modules.
cd /usr/lib/asterisk/modules
dir
There should be a file there called res_config_mysql.so.  If not you need to re-install Asterisk and set it to compile the res_config_mysql.so realtime module in menuselect. Add the following to /etc/asterisk/extconfig.conf
nano /etc/asterisk/extconfig.conf
NOTE: [settings] is already included and uncommented in this file in asterisk sample configurations.  So if you installed asterisk samples or FreePBX and this file already exists and you are trying to add to it, do not add this line twice.
[settings]
iaxusers => mysql,general,cc_iax_buddies
iaxpeers => mysql,general,cc_iax_buddies
sipusers => mysql,general,cc_sip_buddies
sippeers => mysql,general,cc_sip_buddies
extensions => mysql,general,cc_sip_buddies

Add the following to /etc/asterisk/res_config_mysql.conf

nano /etc/asterisk/res_config_mysql.conf
NOTE: [general] is already included and uncommented in this file in asterisk samples.  So if you installed asterisk samples or FreePBX and this file already exists and you are trying to add to it, do not add this line twice.
[general]
dbhost = 127.0.0.1
dbname = mya2billing
dbuser = a2billinguser
dbpass = a2billing
dbport = 3306
;dbsock = /var/lib/mysql/mysql.sock
Assuming (as we did in this guide) that the dbname=mya2billing, dbuser=a2billinguser, dbpassword=a2billing.  Double check that these settings match /etc/a2billing.conf and substitute as necessary.

Now restart freepbx/asterisk

amportal restart

To check if realtime is working:

From Asterisk CLI>
# asterisk -vvvr
 
core show config mappings
Should produce:
Config Engine: mysql
===> extensions (db=general, table=cc_sip_buddies)
===> iaxpeers (db=general, table=cc_iax_buddies)
===> iaxusers (db=general, table=cc_iax_buddies)
===> sippeers (db=general, table=cc_sip_buddies)
===> sipusers (db=general, table=cc_sip_buddies)
After you add a customer to A2Billing, and assuming that customers account number is, for example, 1234567890
realtime load sipusers name 1234567890
should produce:
Column Name  Column Value
-----------  ------------
id           1 
id_cc_card   1 
name         1234567890
accountcode  1234567890
regexten     1234567890
amaflags     billing
callgroup
callerid . . .
maxcallbitrate
outboundproxy
rtpkeepalive  0 
useragent
callbackextension
In the A2Billing GUI go into System settings>Global and search forrealtime. Change that setting to yes if no. If already yes and having problems try change it to no and save and then change back to yes and save.

A2billing - Sorry, you don t have access to this page !

chmod 777 /var/lib/php/session

This fixed the error for me.

Installing FreePBX 2.8 with Asterisk 1.8 on CentOS 5.5

Fonte: http://www.jcarle.com/2010/12/17/installing-freepbx-2-8-with-asterisk-1-8-on-centos-5-5/

FreePBX has become quite popular over the last few years. Unfortunately, the documentation has not quite caught up to the popularity. At the time of this writing, most of the documentation available was for older versions of CentOS, FreePBX and/or Asterix. Below I have outlined the steps required to get FreePBX 2.8 working with Asterisk 1.8 on CentOS 5.5.

If you are reading this as after having followed the steps in my previous article Installing CentOS 5.5 with Linux Integration Services 2.1 on Hyper-V R2 or if you have not selected the following package groups during your installation of CentOS, make sure you do so now by using the following commands.

Preparations

You will need five different passwords.
PASSWORD1 – Your root password.
PASSWORD2 – Used for the asterisk database user.
PASSWORD3 – Used for the FreePBX administrator.
PASSWORD4 – Used for Flash Operator Panel.
PASSWORD5 – Used for the Asterisk Recording Interface.

Requirements

1yum groupinstall "DNS Name Server"
2yum groupinstall "Web Server"
3yum groupinstall "Mail Server"
4yum groupinstall "MySQL Database"
5yum groupinstall "Development Tools"
Once you are sure that the needed package groups are installed, you will want to install the prerequisites as follows.
1yum install e2fsprogs-devel keyutils-libs-devel krb5-devel libogg libselinux-devel libsepol-devel libxml2-devel libtiff-devel
2yum install gmp php-pear php-pear-DB php-gd php-mysql php-pdo kernel-devel ncurses-devel audiofile-devel libogg-devel
3yum install openssl-devel mysql-devel zlib-devel perl-DateManip sendmail-cf sox
Make sure you also have wget installed.
1yum install wget
Next you will setup named.
1echo "options {" >> /var/named/chroot//etc/named.conf
2echo " directory \"/var/named\";" >> /var/named/chroot//etc/named.conf
3echo " dump-file \"/var/named/data/cache_dump.db\";" >> /var/named/chroot//etc/named.conf
4echo " statistics-file \"/var/named/data/named_stats.txt\";" >> /var/named/chroot//etc/named.conf
5echo "};" >> /var/named/chroot//etc/named.conf
6echo "include \"/etc/rndc.key\";" >> /var/named/chroot//etc/named.conf
7cd /var/named/chroot//etc/
8chmod 640 named.conf
9chgrp named named.conf
10ln -s /var/named/chroot//etc/named.conf /etc/named.conf
You will want to adjust the security settings as per your requirements but for the simplicity of this article, we are going to turn off Security-Enhanced Linux and open the firewall fully.
1echo "SELINUX=disabled" > /etc/selinux/config
2iptables -P INPUT ACCEPT
3iptables -P OUTPUT ACCEPT
4iptables -P FORWARD ACCEPT
5iptables -F
6iptables -X
7/etc/init.d/iptables save
LAME is required for Asterisk’s audio related functions. You will want to download LAME to a source directory, compile and then install it.
1cd /usr/src
2wget http://downloads.sourceforge.net/project/lame/lame/3.98.4/lame-3.98.4.tar.gz?ts=1292626574&use_mirror=cdnetworks-us-1
3tar zxvf lame-3.98.4.tar.gz
4cd lame-3.98.4
5./configure
6make
7make install
You can optionally remove the source once you have installed LAME.
1cd ..
2rm -fr lame-3.98.4
3rm lame-3.98.4.tar.gz
Before continuing, insure that all packages are up to date and then reboot.
1yum update
2reboot

Installing Asterisk 1.8

Get Asterisk 1.8 and extract it to its own source folder.
1cd /usr/src
2wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-1.8-current.tar.gz
3tar xvfz asterisk-1.8-current.tar.gz
4cd asterisk-1.8.0
5contrib/scripts/get_mp3_source.sh
6./configure
7make menuconfig
The last command will launch the source configuration manager. The only portions you will want to install are app_mysql, app_saycountpl, cdr_mysql, format_mp3, res_config_mysql and EXTRAS-SOUNDS-EN-GSM (which can be found in the Extra Sound Packages sub-menu). Save your selections and exit. Now compile the source and install.
1make
2make install
You can optionally remove the source directory once you have installed Asterisk.
1cd ..
2rm -fR asterisk-1.8.0
3rm asterisk-1.8-current.tar.gz

Installing FreePBX 2.8

Get FreePBX 2.8 and extract it to its own source folder.
1cd /usr/src
2wget http://mirror.freepbx.org/freepbx-2.8.0.tar.gz
3tar xvfz freepbx-2.8.0.tar.gz
4cd freepbx-2.8.0

2chown -R asterisk:asterisk /var/run/asterisk
3chown -R asterisk:asterisk /var/log/asterisk
4chown -R asterisk:asterisk /var/lib/php/session/
Update the Apache configuration file.
1vi /etc/httpd/conf/httpd.conf
Change User apache and Group apache to User asterisk and Group asterisk.
Change AllowOverride None to AllowOverride All.
Update ServerName to use your server’s FQDN.
Start Apache.
1/etc/init.d/httpd start
2chkconfig httpd on
Start Asterisk.
1./start_asterisk start
Configure FreePBX.
1./install_amp --username=asteriskuser --password=PASSWORD2
The next series of prompts will give you default values within square brackets which you can accept by hitting enter. If you wish to change a value, simply type it and hit enter after.
1[asteriskuser]
This is the database user you specified earlier.

Use the default value.
1[/usr/local/sbin]
Use the default value.
Change the Asterisk Recording Interface password and turn on user authentication for the web interface by editing the amportal.conf file.
1vi /etc/amportal.conf
Change the ARI_ADMIN_PASSWORD entry to update the ARI password.
1ARI_ADMIN_PASSWORD=PASSWORD5
Change the AUTHTYPE entry to database to enable authentication.
1AUTHTYPE=database
Optionally, you can turn off the FOP completely by changing the following settings.
1FOPRUN=false
2FOPDISABLE=true
Save and exit.
Add FreePBX to the boot process.
1echo "/usr/local/sbin/amportal start" >> /etc/rc.local
You can ensure that the administrator user has the proper password in the database by navigating to the Administrators tab, choosing the admin user and clicking on the Update password link. Once your password has been updated, logout by clicking the link at the top right of the page.
Finally, reboot the server one last time.

Elastix - Permissão de acesso a úsuarios no Monitoring

Fonte: http://anaqueilati.blogspot.com.br/2013/03/elastix-permitir-um-usuario-qualquer.html


Tive alguns problemas para resolver uma questão no Elastix e resolvi fazer este Post para ajudar quem estiver na mesma situação que a minha, no Elastix o único grupo que tem permissão para acessar ao Monitoring é o Administrador, usuário comum não tem acesso. Mas precisava que um usuário sem permissão administrador conseguisse visualizar as ligações. Em algumas buscas achei a seguinte solução:

Editar o arquivo /var/www/html/modules/monitoring/index.php


Abaixo das linhas


$extension = $pACL->getUserExtension($user);
$esAdministrador = $pACL->isUserAdministratorGroup($user);

Inserir as seguintes linhas abaixo, onde "usuario" será o usuário que você deseja que tenha permissão para visualizar a aba ligações no Monitoring. 

if ($_SESSION['elastix_user'] == 'usuario')
$esAdministrador = TRUE;
