Creating custom records and archiving Call Detail Records was once a difficult task. However, 3CX Exporter has now made the job easy for you. Moving Call Detail Records from 3CX to SQL Server or MySQL reduces the demands on your 3CX server, and allows you to use the tools you already know to create custom reports.

1.1. What is 3CX Exporter?

3CX Exporter automates the export of Call Detail Records (CDR) from 3CX’s internal PostgreSQL database to either Microsoft SQL server or MySQL. This small Windows service runs automatically in the background to keep your external database in sync with the data in 3CX.

1.2. Why 3CX Exporter?

1. Make it possible to create custom reports.

2. To integrate (utilize) that data in other applications (like CRM integrations).

1.3. How to use 3CX Exporter?

3CX Exporter is a onetime installation process. Once you install it, the product will automate the export of Call Detail Records according to the export frequency you set during the installation process. However, in future, you can change both the export frequency and database as well.


Before installing 3CX Exporter, you need to ensure that your computer meets the minimum requirements mentioned below:

1. 3CX Version V16 and V18

2. Windows 10 or above

3. Microsoft SQL Server 2014 or above (Including the free SQL Express edition), or MYSQL

4. Windows Server 2012 (64 bit) or above

5. .Net 4.7.2

6. If you are installing 3CX Exporter in a server other than 3CX Server, then you should install ‘C++ 2010 redistribution package (X86)’ in the 3CX Server. You can install it from the link: https://my.visualstudio.com/Downloads?pid=963

Step 4: Download 3CX Relay (if required)

3CX permits one 3rd party application to communicate with the 3CX server at a time. To overcome this limitation, VoIPTools created the 3CX Relay Service. The Relay is a lightweight application that is installed directly on the 3CX server. The Relay exposes the 3CX Call Control API (and other VoIPTools services) to all our applications, and manages requests and events between by VoIPTools products and 3CX.

The Relay also makes it possible to install our VoIPTools products on a remote server (including over the internet).

1. If you have not previously installed the Relay on your 3CX Server, you can download the Relay installer by clicking on the Download Relay button. The Relay must be installed directly on the 3CX server.

2. If you are installing 3CX Exporter directly on the 3CX server, you can install the Relay simply by clicking the Install/ Upgrade Relay button and following the Relay install instructions.

If you have already installed the Relay, you need not install it again unless a newer version is required.

Step 5: Test Relay Settings

1. In the Relay Type drop down, select Legacy Relay for old Relay or New Relay for new Relay based on the 3CX version of your application.

Figure 2: Test VoIPTools 3CX Relay settings

If you choose ‘Relay Type’ as ‘Legacy Relay’ then ‘3CX Exporter’ will communicate with old Relay Service, and if you choose ‘New Relay’ then it will communicate with new Relay Service.

2. In the Relay Services Host field, enter “localhost” if installing ‘3CX Exporter’ on the 3CX server. If 3CX resides on a different server, enter the IP address or FQDN of the 3CX server.

3. In the Relay Services Port field, enter the value as 8700 for Legacy Relay or 8800 for New Relay.

Figure 3: Relay Services Port

The ‘3CX Exporter’ will take default port as 8700 for ‘Legacy Relay’ and 8800 for ‘New Relay’. If the default port number doesn’t appear automatically, you can manually enter the respective default port number.

4. Click Test Relay Settings to confirm ‘3CX Exporter’ can communicate with the Relay services running on the 3CX server.

5. If the ‘3CX Exporter’ is successfully able to communicate with the Relay services that run on the 3CX server, a Success message box appears. Click OK.

Figure 4: Success message box

6. Click Next to continue the installation.

Step 6: Run the application

d. Click OK to close the test results dialog

5.3. Export tab

In the Export screen, you can setup the exporting of tables. From here, you can select and export the desired tables from the list. Exporting of tables from ‘3CX DB’ to ‘Exporter DB’ will take place in 3 scenarios:

(i) Based on the setup export frequency

(ii) When you click Export button

(iii) When you start 3CX Exporter service.

Figure 12: Setup Export Frequency


1. In the Export tab, set Export frequency (in seconds) value. This is the frequency for automatic synchronizing of updates from 3CX database to Exporter database.

2. Check the desired export tables that you want to delete.

3. Click Save

5.4. CDR Settings tab

Enter Domain Name, User Name and Password if the 3CX Exporter and PBX are on different servers, so that the web server (IIS) can access the Call Detail Records (CDR) and update the database.

Figure 13: Configure CDR Settings


1. To process CDR files, check Process CDR Files check box.

2. In the CDR Settings section, and in the Cdr Path field, enter the path where the cdr files should be stored in 3CX Console.

3. In the Delete Policy section, check the Delete processed CDRs older than check box if you want to enable the delete policy.<.p>

4. In the Days field, enter the number of days so that the processed cdr files older than the specified number of days will be deleted automatically at the scheduled Delete at timing.

5. In the Delete at time box, enter the time using up and down arrows so that the scheduler will delete the processed cdr files older than specified number of days at the scheduled time.

6.Call Detail Records (CDR) Files

In addition to exporting data directly from the 3CX PostgreSQL database, Exporter can also export Call Detail Records (CDR) created by 3CX as text files. Instructions for configuring 3CX to create these optional files are outlined below. The CDR files contain useful information about every phone call including participants, duration, the call chain, etc. While the CDR files do not include the same level of detail available in the PostgreSQL database, the data structure is far easier to understand. If the CDR files contain all the information you need, it is recommended that you utilize the CDR files rather than accessing the PostgreSQL database.

6.1.Configure 3CX to Automatically Create CDR Files

1. Log in to 3CX Management Console with valid credentials.

2. On the left navigation pane, select Settings from the menu.

3. In the Settings screen, select the $CDR icon to display the CDR Settings screen.

Figure 14: Settings menu

4. Check Generate CDR checkbox

5. Select Separate files for each call from the combo box.

It is important that you configure 3CX to save each call as an individual file.
