To enable 3CX alerts, turn on its permission in Windows at Start > Settings > System > Notifications. Configure call shortcuts in the installed Softphone’s Settings, under its hotkeys controls. “Startup” can mean leaving 3CX running in the tray, launching it automatically at sign-in, or deploying it with Group Policy; those are separate tasks, and current official documentation does not establish a user-facing auto-launch setting or path.

Turn on 3CX notifications in Windows

  1. Open Start > Settings > System > Notifications.
  2. Find 3CX in the app list and switch its notifications on. Make sure Windows allows the app to send notifications.

These are Windows notification permissions, not a hidden in-app notification switch. 3CX’s [April 2025 guidance on chat notifications] points users to this Windows setting when troubleshooting missing alerts. The Softphone is designed to work in the background and notify users of incoming calls and messages, but Windows permissions and notification settings still affect whether alerts appear on a particular PC, as described in 3CX’s [March 2024 announcement].

Set up Softphone hotkeys

Open Settings in the installed Windows Softphone and locate its hotkeys controls. The exact label or location can vary by build; an older Windows Client manual’s “Hot Keys” page is not reliable guidance for the current Softphone interface. If you cannot find the controls, check the installed build and documentation provided by your administrator.

3CX says hotkeys work while the app is minimized to the taskbar or system tray. Its build history records a hotkeys-page fix in V5.8 beta in August 2026; that beta note should not be treated as a description of production behavior. 3CX announced Windows Softphone V5.5 production on March 30, 2026. See the [Windows Softphone build history] and [V5.5 production announcement].

Choose what “startup” means

Goal What to do What is established
Keep 3CX available in the background Minimize the app to the system tray rather than exiting it. 3CX documents background operation and tray use. To close the app, right-click its tray icon and choose Exit.
Launch 3CX when a user signs in Look for an auto-launch control in the installed production app, or ask your administrator. The current official sources do not establish a user-facing toggle or its exact path. Do not assume instructions for the older Windows Client apply to the Softphone.
Deploy for users through domain policy An administrator can follow 3CX’s Group Policy deployment guide. This is managed deployment, not a personal auto-start preference. The guide specifies fully updated Windows Server 2025 and Windows 11 clients as prerequisites for its documented procedure.

For the documented domain deployment, the administrator places the MSIX package and PowerShell script on a network share and configures Group Policy startup and logon scripts. The [3CX GPO deployment guide] also lists command-line settings such as --host, --echo-cancellation, --ringer-volume, and --mic-gain. The Softphone must be installed and fully closed before applying those settings; running the commands launches the app. They cover provisioning, audio, and integrations—not hotkeys or a user-level auto-launch preference. The guide’s OS prerequisites apply to that deployment method, not necessarily to every Softphone installation.

Optional: choose audio devices for calls

If you also need to configure call audio, 3CX troubleshooting guidance recommends selecting a headset for the microphone, speaker, and ringing roles. You can use a separate output device, such as a speaker, for ringing. A headset is an audio choice, not a requirement for notifications, hotkeys, or startup setup. See [3CX Softphone troubleshooting].
