3CX Auto Voicemail allows your staff to record personalized voicemail messages, and automatically play these messages when connected to a customer’s voicemail box.
Primarily envisioned for call center agents who are making outbound calls, when a call center agent is transferred to a customer’s voicemail box, the agent can select from a list of prerecorded messages and have 3CX leave the voicemail for them.

Having 3CX leave the voicemail has the following benefits:

  • Immediately disconnects the agent from the call, thus instantly making the agent available to place the next call.
  • Relieves some of the tedium of leaving repetitious voicemails by having 3CX do it for you.
  • Eliminates wasted time saying the same voicemail message over and over throughout the day.
  • Ensures a consistent, carefully crafted voicemail is delivered every time.


Before installing Auto Voicemail, you need to ensure that your computer meets the minimum requirements mentioned below:

1. 3CX Version V16 and V18

2. Windows 10 or above / Windows Server 2012 or above

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

4. Internet Information Server (IIS) 7.0 or above

5. .Net 4.7.2 or above

  • When installing SQL Server, we recommend you install it in “Mixed Mode” to include SQL Authentication, and install SQL Management Studio
  • When installing IIS, be sure to install Basic Authentication, .Net Extensibility, and ASP.Net 4.X

Figure 1: VoIPTools 3CX Auto Voicemail Setup Wizard

Step 4: Download the VoIPTools 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 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 Auto Voicemail 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 Auto Voicemail’ 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 Auto Voicemail’ 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 Auto Voicemail’ 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 Auto Voicemail’ can communicate with the Relay services running on the 3CX server.

5. If the ‘3CX Auto Voicemail’ 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: Configure the database
If this is your first install then, select a valid SQL server and if you are reinstalling then select the existing database.

1. When prompted for the database connection information, click Configure.

Figure 5: Configure Database

2. In the Connection Properties dialog box, enter the SQL server name. If using the free SQL Express edition, the default SQL Instance name is SQLExpress. DO NOT use “local host” or “(local)” for the server name.

If you want to use ‘SQL Authentication’, then install SQL Server in ‘Mixed‘ mode.

Figure 6: Connection Properties

i. In the Connection Properties dialog box, and under Log on to the server section:

a. Select Use SQL Server Authentication option and enter valid SQL login account and password.

If SQL Server is installed on a server other than the server where 3CX Auto Voicemail is installed, you will need to configure SQL Server to allow remote connections.

Figure 7: Windows Authentication

b. Technical administrators can alternatively select Use SQL Server Authentication, but we recommend using SQL Authentication when possible.

  • 3CX Auto Voicemail installs a Call Flow Designer application automatically on the 3CX server. This application must connect to the SQL Server database. SQL Authentication eleminates login issues where the servers are not participating in a Active Directory domain.
  • The VoIPTools installer will automatically create a local “VoIPTools” user account. This account can authenticate to SQL server and is given the necessary access permissions to create / update the database. The web portal runs under the VoIPTools credentials.

Figure 8: SQL Server Authentication

3. To have the installer create the database for you, leave the Select or enter a database name field blank. To use a pre-existing database, select the desired database from the drop-down list.

4. Click the Test Connection button to confirm connectivity to SQL Server.

5. Click OK to save the SQL Connection information.

6. Click Next to create the required SQL database objects.

Figure 9: Configure Database

7. The server installation status screen will display the installation progress.

Figure 10: Installation in progress

8. An alert message appears that suggests you perform the installation only when you don’t have any active calls running.

i. Click OK if you don’t have any active calls running to continue the installation.

If there are any active calls running, and if you click OK, you may drop the calls. VoIPTools recommends you to perform this install during a period of low or no important call activity.

ii. Click Cancel if you want to cancel the installation process and retry when you don’t have any active calls running.

Figure 11: Alert Message

3CX requires that you must have the professional edition of 3CX or higher to use Voice Apps.

9. When the software installation is complete, click Close

Figure 12: Close Application

If 3CX and SQL are on a separate server, you will need to configure SQL Server to accept remote connections, and ensure you have name resolution between the two servers. Name resolution can be implemented through DNS or by editing the host files on each server.
