1. Verify Operating System Notification Settings

Your computer’s OS-level notification controls may prevent the Sangoma Talk Desktop app from displaying alerts.

Windows

  • Open Settings > System > Notifications & Actions

  • Confirm Notifications are enabled globally

  • Scroll down and ensure Sangoma Talk / Sangoma Phone Desktop is allowed to:

    • Show banners

    • Play sounds

    • Display notifications while the app is minimized or running in the background

macOS

  • Select Sangoma Talk / Sangoma Phone Desktop

  • Ensure the following are enabled:

    • Allow Notifications

    • Banners or Alerts

    • Play sound for notifications

System Updates

Outdated operating systems can cause notification framework conflicts.
