Billing for FusionPBX Configuration

To configure LCR for FusionPBX, you need to understand the following concepts:

Profile

A Profile is used to define a billing. Each profile is identified by a unique label.

Billing Cycle

A Billing Cycle defines the billing day. Static charges will take place this day.

Billing Type

A billing type may be pre or postpaid.

Amount

The specific amount, on post-paid profiles it establishes the maximum credit a profile may have. This value is zero for pre-paid profiles. You must define billing currency, the system will use external services to do the rating.

LCR profile

LCR profile is a pricing list. By changing this label, you may have more than one pricing list.

Refered

Referal fields let you reward your users just because they recommend your service.

After:

1. Go to Apps->Billing menu and add a profile
2. Fill the next information
   Select FROM and TO depending who shall send the billing to who. Data will be taken according to information in Contacts application; you can go to App -> Contacts menu to fill information.
   In most cases, using billing per tenant is enough, but there are specific cases where an alternate code is required, especially if you need more than one billing profile per tenant; in this case, select the by-code option. The value entered in the Criteria Value field needs to be in place on all other FusionPBX items.
   Select the billing day cycle, to make things simple it is only allowed from 1 to 28.
   The Amount field is read-only, you must select the currency for billing. Once the currency is set, you won't be able to change it.
   Delay days field is not used.
   Balance is a read-only field.
   LCR profile field will tell the profile what pricing list to use. By default it is 'default', by adding a new profile means to modify file lcr.conf.xml.
   Referal fields are sued to reward your users because of recommendations.

Remember to fill the accountcode field with the correct value when creating items in FusionPBX.

Maintenance Tasks

1. billing_crontab_pyramid.php

The application architecture within the /app directory of FusionPBX allows a very quick installation. Please follow the following steps:

Install ShadowPHP

ShadowPHP is encryption technology that Billing for FusionPBX uses. It is important to properly install this component.

1. Download the server extension to the version of PHP running. The extension can be downloaded from http://phpshadow.com/download.php.
2. Inside, you will find the downloaded extension file phpshadow.so, copy it into the directory of modules. If you do not know the route, the php command php -rr "echo ini_get ('extension_dir');" will show you the route.
3. Edit the php.ini file and add the line extension = phpshadow.so, some Linux distributions have php.d directory, you can put into a single file and add the line.
4. Restart your apache server.

If you are in doubt about how to configure ShadowPHP extension, you will find this site http://phpshadow.com/download.php very useful. There is a User Guide (in English) that explains step by step how to install.

Download and Install the LCR and Billing for FusionPBX

The next step is to install the software as such. Please download both applications. The Billing application requires LCR. FusionPBX must be configured with a database backend such as MySQL (or MariaDB) or PostgreSQL. Follow the following steps:

1. Download both applications.
2. Copy both .tar.bz2 extension files into FusionPBX server. In this example we will assume that both files are in the /root directory and FusionPBX is installed in /var/www/html directory.
3. Change to /var/www/html/app directory.  Here is where applications are. You can type cd /var/www/html/app.
4. Expand both tar.bz2 files with tar -jxvf /root/lcr-crypted.tar.bz2 and tar -jxvf /root/billing-crypted.tar.bz2 commands.
5. Run php /var/www/html/core/upgrade/upgrade_schema.php. The command will display various SQL statements that indicate that they are building the necessary tables in the database.
6. Log into FusionPBX as a super-administrator and go to the menu System-> Menu Manager, edit the default menu (default) and select the option Restore defaults.
7. Go to the menu Advanced-> Group Manager and edit the permissions of the super-administrators group. Check that the permissions for LCR and Billing are checked.
8. Install the Enhanced XML Importer, change to /var/www/html/app directory and type git clone https://bitbucket.org/okay-network/fusionpbx-enhanced-cdr-importer/src/master/ enhanced-cdr-importer
9. Edit the /etc/freeswitch/autoload_config/xml_cdr.conf.xml file and edit or add the following line:
   <param name="url" value="http://127.0.0.1/app/enhanced-cdr-importer/xml_cdr_import.php"/>
10. Reload the mod_xml_cdr module, you can type reload mod_xml_cdr from the FreeSWITCH console.

Installation Using RPM's

If you are using CentOS 6, 7 and 8 you can do the following:

1. Install the OKay RPM repository, follow directions on this page.
2. After the repository is installed, type: yum install fusionpbx-all, confirm the questions and wait.
3. Finish the installation by accessing to http://IP/fusionpbx/, use the following default data (you can change it):
   • database name: fusionpbx
   • database username: fusionpbx
   • database password: c4rl0s3l4rt1st4
   • database host: 127.0.0.1

At this time the application is ready to be configured.
