Bluetooth Generic Telephony Service Driver

The Bluetooth Generic Telephony Service driver helps Windows recognize and communicate with a telephony-related Bluetooth service through compatible Broadcom Bluetooth software. You may need it if Device Manager lists this service as an unknown device or shows a warning after you pair a Bluetooth phone, headset, or other device offering calling features. The correct package depends on your computer’s Bluetooth adapter and software stack, not just the service name.

Key Features

• Bluetooth service recognition: Helps Windows identify a telephony-related service exposed by a paired Bluetooth device.
• Broadcom software integration: Works with a compatible Broadcom Bluetooth stack to support communication between Windows and the paired device.
• Driver issue resolution: Installing a matching package may resolve missing-driver warnings or service detection problems in Device Manager.
• Legacy Windows support: Relevant packages may be available for Windows 10, 8.1, 7, Vista, and XP; compatibility varies by package, adapter, and system architecture.

How to Install Bluetooth Generic Telephony Service Driver

1. Identify your hardware. Open Device Manager and locate the Bluetooth adapter and any Bluetooth Generic Telephony Service entry. Check their properties for hardware IDs and note your computer model.
2. Confirm Windows compatibility. Before choosing a Bluetooth Generic Telephony Service driver download for Windows, verify your OS version and whether it is 32-bit or 64-bit. For Windows 10/11 systems, check support explicitly: a Windows 10 listing does not establish Windows 11 compatibility.
3. Choose a trusted package. Look for the latest version approved for your computer or Bluetooth adapter through the manufacturer’s support resources or Windows Update. A free download should still have a verifiable source and a compatible digital signature.
4. Install the driver. Run the compatible Bluetooth package installer and follow its instructions. If the manufacturer supplies extracted driver files, use Device Manager’s Update driver option and browse to the supplied folder.
5. Restart and test. Restart Windows if prompted, reconnect the Bluetooth device, and check whether the warning has cleared. Test the calling features your hardware and software support; installing a driver does not add unsupported capabilities.

Keep your Bluetooth software updated to address compatibility issues and known bugs. Before an update, confirm that the release supports your exact adapter and Windows version. If the current setup works reliably, avoid replacing it with an unrelated package simply because its version number is newer.

Common Issues and Fixes

• Install fails or rolls back: The telephony service driver depends on a working Broadcom Bluetooth adapter driver. Install/update the adapter driver first, reboot, then retry; do not install this service alone on a PC without the paired hands-free device.
• Device not detected: Confirm Bluetooth is on, the headset/carkit is in pairing/HFP mode, and “Bluetooth Support Service” is running. Remove the device in Settings, re-pair, then check Device Manager under Bluetooth for the Generic Telephony Service.
• Version conflicts/code 10 or 43: Mixed Windows Update and OEM Broadcom packages can conflict. In Device Manager, uninstall the Broadcom Bluetooth adapter and telephony entries (show hidden devices), reboot, and install the latest OEM adapter driver matching your Windows version.
