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

3). Click Next to continue.

Step 4: Test Relay Settings

1). In the 3CX Relay Services window, in the Relay Host field, enter the IP address or FQDN of your 3CX server.

Figure 11: Test VoIPTools 3CX Relay settings

2). To maximize security, we strongly urge you to configure the Relay and 3CX Queue Notifier to use of https (TLS encryption).  To use TLS security, ensure the Relay Port is set to 8801 and the Protocol to HTTPS.  However, if your Relay is not configured to use TLS encryption, change the Relay Port to 8800 and the Protocol to HTTP.

Figure 12: Relay Protocol

3). Click Test Relay Settings to confirm ‘3CX Queue Notifier’ can communicate with the Relay services running on the 3CX server.

If the test was unsuccessful: 

(1) confirm you have the correct firewall port open (default TCP 8801) on the 3CX server and the firewall protecting the 3CX server.
(2) confirm that you have entered the correct IP address / FQDN for the 3CX server.
(3) confirm that 3CX Queue Notifier and the Relay are using the same port and protocol.

4). 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. If the test fails, you will not be able to continue until communication with the relay is established.

Figure 13: Success message box

5). Click Next to continue with the installation.

Step 5: Configure the database

When configuring 3CX Queue Notifier, select an existing Microsoft SQL Server instance in your environment.  The database server can be a remote SQL Server (How-to configure SQL Server to permit remote connections), or a local instance running on the VoIPTools server.

1). On the SQL Database window, in the Server field, select the desired instance of SQL Server

We encourage you to use SQL Authentication rather than Windows authentication.  Many of our tools leverage a Call Flow Designer (CFD) application running on the 3CX.  Frequently our CFD applications require access to a SQL database.  If the 3CX server and the database server are not in an Active Directory domain, Windows authentication will fail.  To use SQL authentication, your SQL Server must be configured to run in “Mixed Mode”.  If you installed SQL Server with one of our tools, we configure SQL in “Mixed Mode”.

Figure 14: SQL Authentication

2). To use SQL Authentication, be sure to uncheck the Trusted Connection checkbox.

3). In the Username and Password fields, enter valid SQL login account credentials

Figure 15: Configure Database

4). To use Windows Integrated Authentication (not recommended), check the Trusted Connection (Windows integrated authentication) checkbox.

5). In the Database field, the installer will automatically display the default database name.  We encourage you to use the default name.  If you are upgrading or reinstalling 3CX Queue Notifier, select the existing database name from the list.

6). Click the Test Sql Connection button to confirm connectivity to SQL Server and then click Next to continue.
