Hello,
I'd be happy to give you some suggestions and ideas.
From what you described, the most likely reasons are:
- The Bluetooth adapter on your desktop computer does not support HFP (Hands-Free Calling Profile).
- Windows does not correctly enable call audio permissions.
- It is a configuration issue related to the hardware or driver, not a bug in the Phone Link app itself.
Check if your computer's Bluetooth supports calls (HFP protocol) To make calls, your computer's Bluetooth device needs to support HFP (Hands-Free Profile). How to check:
- Press Win + X > Open Device Manager.
- Expand "Bluetooth".
- Find your Bluetooth adapter (maybe Intel or Realtek, etc.)
- Right-click > Properties > View the "Details" or "Advanced" tab.
- Check if there is support for Hands-Free Telephony or HFP. If not, your Bluetooth adapter does not support the call function.
Solution: Try to update the Bluetooth driver (download from the motherboard or Bluetooth device manufacturer's official website). Or use a USB Bluetooth adapter that supports the HFP protocol (recommended: ASUS USB-BT500, etc.).
Check Windows Services The following system services must be enabled:
- Press Win + R, type services.msc, and hit Enter.
- Find and make sure the following services are "Running" and set to "Automatic" startup:
- Bluetooth Support Service
- Device Association Service
- Bluetooth Audio Gateway Service (if present)
Check the Event Viewer log
- Press Win + R, type eventvwr.msc.
- Look for errors or warnings related to Phone Link or Bluetooth, especially around the time when you tried to make a call.
Regards,
Allison
