Do you need an audible chime when too many people are waiting in the queue? This add-on enables you to set a threshold for the maximum number of people in the queue or maximum hold time.

1.1. How 3CX Queue Notifier works?

Scenario: Your staff is often busy and spends much of their time away from their desks. Perhaps they need a nudge to remind them people are waiting in a queue. With 3cx Queue Notifier (Queue Chime) you can play over an overhead paging system (or through the phone speakers) a chime indicating the number of people waiting in the queue. Alternatively, you can play a text-to-speech message stating the number of people in the queue and the longest hold time.


Before you begin with the installation steps mentioned in this guide, you need to ensure that your computer meets the minimum requirements mentioned below for installing 3CX Queue Notifier.

1. 3CX Version V16 and V18 (Professional or Enterprise Version Only)

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

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

4. .Net 4.7.2 or above

5. Microsoft Internet Information Server (IIS) 7.0 or above

6. Installation on a domain controller is not supported

  • 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: 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 Queue Notifier 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 3CX Server Platform drop down, select Windows for old Relay or Linux for new Relay based on the 3CX version of your application.

Figure 2: Test VoIPTools 3CX Relay settings

If you choose ‘3CX Server Platform’ as ‘Windows’ then ‘3CX Queue Notifier’ will communicate with old Relay Service, and if you choose ‘Linux’ then it will communicate with new Relay Service.

2. In the Relay Services Host field, enter “localhost” if installing ‘3CX Queue Notifier’ 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 Windows or 8800 for Linux.

Figure 3: Relay Services Port

The ‘3CX Queue Notifier’ will take default port as 8700 for Windows and 8800 for Linux. 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 Queue Notifier’ can communicate with the Relay services running on the 3CX server.

5. If the ‘3CX Queue Notifier’ 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.

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


  • If SQL Server is installed on a server other than the server where 3CX Queue Notifier is installed, you will need to configure SQL Server to allow remote connections

Figure 6: Connection Properties

3. Enter the login credentials.

a. If using Windows integrated security, select Use Windows Authentication. The VoIPTools installer will create a local windows user name as “VoIPToys” and will give sufficient rights to this user to create / update the SQL database.

Figure 7: Windows Authentication

b. If SQL Server authentication is desired, select Use SQL Server Authentication. Be sure to select a SQL Login that has sufficient permissions to alter the database and create SQL objects. Enter the User name and Password, and select appropriate database value from the Select or enter a database name drop down.

Figure 8: SQL Server Authentication

The first time you install 3CX Queue Notifier, DO NOT enter a database name. Choose Select or enter a database name and leave the database name blank. The installer will create the SQL database automatically and apply the necessary permissions. If upgrading 3CX Queue Notifier from a previous version, select the existing database from the list.

4. Click Test Connection button to confirm you can connect to SQL

5. Click OK to close the test results dialog
