# Prerequisites

Ensure your computer meets the minimum requirements outlined below before installing 3CX Audio Scheduler,

| **PREREQUISITE** | **PURPOSE** |
| --- | --- |
| **3CX Version V20** | 3CX Audio Scheduler is designed to work seamlessly with this version for enhanced features and performance. |
| **Windows 10 or above / Windows Server 2012 or above** | These operating systems provide the necessary environment for the application to run efficiently. |
| **[IIS Features and Configuration – VoIPTools](https://voiptools.com/docs/iis-features-and-configuration/)** | IIS is needed as a web server to host and manage web-based applications and services. |
| **.NET Framework 4.7.2 (Web Installer)** | This framework provides essential components for running and developing applications. |
| **VoIPTools Universal Updater** | This component is necessary for updates, ensuring the application remains current and functional. |
| **Microsoft SQL Server 2016 or above (Including the free SQL Express edition)** | 3CX requires Microsoft SQL Server 2016 or later for database management. |
| **Static IP for VoIPTools and 3CX servers** | This is to ensure proper two-way communication, both the 3CX server (Relay) and the VoIPTools server. Dynamically assigned IP addresses are not supported. Additionally, it is recommended to use HTTPS for secure communication, which requires a FQDN for SSL/TLS certificate validation between the VoIPTools server and the Relay. |
| **Port number 5950 opened on your device** | Port 5950 is a specific network port used by 3CX for communication purposes. Opening this port on the device’s firewall allows incoming and outgoing traffic to pass through, enabling the 3CX software to send and receive data over the network effectively. |

> ![](https://voiptools.com/wp-content/uploads/2025/10/sticky_note_2_50dp.png) **NOTE**:
>
>
>
> When installing IIS, be sure to install Basic Authentication, .Net Extensibility, and ASP.Net 4.X

![](https://voiptools.com/wp-content/uploads/2024/07/screenshot-audio-scheduler-test-relay-success.png)
Figure 12: Test Relay Success

> ![](https://voiptools.com/wp-content/uploads/2025/10/sticky_note_2_50dp.png) **NOTE:**
>
>
>
> - You must set the Relay Port to 8801.
> - *If the Relay test fails, you cannot continue the installation until you establish communication with the Relay.* If the test was unsuccessful:
>   - Confirm you have the correct firewall port open (default TCP 8801) on the 3CX server and the firewall protecting the 3CX server.
>   - Confirm that you have entered the correct FQDN for the 3CX server.
>   - Confirm that the 3CX Power Dialer and Relay use the same port and protocol.

## Step 5: Configure the database

When configuring the 3CX Audio Scheduler, select an existing Microsoft SQL Server instance in your environment.  The database server can be a **[remote SQL Server](https://voiptools.com/docs/configure-sql-server-for-remote-access-over-internet/)**, or a local instance running on the VoIPTools server.

You can set up the SQL database using SQL Authentication or Windows Integrated Authentication.

### SQL Authentication

1. Enter *your server’s name* in the **Server** field.
   -  If using the free ***SQL Express Edition***, the default SQL Instance name is ***SQLExpress***.

![](https://voiptools.com/wp-content/uploads/2024/07/screenshot-audio-scheduler-configure-database-server-field.png)
Figure 13: Configure Database – Server Field

> ![](https://voiptools.com/wp-content/uploads/2025/10/sticky_note_2_50dp.png) **NOTE:**
>
>
>
> - 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 Exporter is installed, you will need to configure SQL Server to allow remote connections.

1. Enter *your credentials* in the**Username** and**Password** fields.

![](https://voiptools.com/wp-content/uploads/2024/07/screenshot-audio-scheduler-database-credentials.png)
Figure 14: Configure Database – Database Credentials

> ![](https://voiptools.com/wp-content/uploads/2025/10/sticky_note_2_50dp.png) **NOTE:**
>
>
>
> Make sure that you select a SQL Login that has sufficient permissions to alter the database and create SQL objects.

1. Select or enter the *3CX Emergency Notifier* in the **Database** dropdown.

![](https://voiptools.com/wp-content/uploads/2024/07/screenshot-audio-scheduler-database-dropdown.png)
Figure 15: Configure Database – Database Dropdown

1. In the **Test SQL Connections** section, click the **Tool**button to test the connection and click **OK**in the **Test Results**popup box.

![](https://voiptools.com/wp-content/uploads/2024/07/screenshot-audio-scheduler-sql-connection-successed.png)
Figure 16: Test SQL Connection

### Windows Integrated Authentication

1. To use **Windows Integrated Authentication** check the **Trusted Connection (Windows integrated authentication)** checkbox.
   -  The VoIPTools installer will create a local Windows user name as “VoIPToys” and give you sufficient rights to this user to create/update the SQL database.

![](https://voiptools.com/wp-content/uploads/2024/07/screenshot-audio-scheduler-trusted-connection-checkbox.png)
Figure 17: Trusted Connection Checkbox

1. In the **Test SQL Connection** section, click the **Tool**button to test the connection.
2. Click the **Next**button which gets enabled when the database connection is successful.

![](https://voiptools.com/wp-content/uploads/2024/07/screenshot-audio-scheduler-trusted-connection-success.png)
Figure 18: Trusted Connection Test Results Message Box

> ![](https://voiptools.com/wp-content/uploads/2025/10/sticky_note_2_50dp.png) **NOTE**:
>
>
>
> 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”.

## Step 6: Installing 3CX Audio Scheduler

1. On **the Ready to Install**screen, press **Install** to install 3CX Audio Scheduler.
