Phone Link does not provide a setting to keep the iPhone linked but prevent active iPhone calls from transferring to the PC automatically.
The available controls for Phone Link focus on enabling or disabling whole features (Calls, Messages, Notifications, etc.), not on changing how individual calls are routed once the iPhone is connected over Bluetooth. For iPhone, calls on the PC are enabled by having the devices paired via Bluetooth and the Calls feature turned on; there is no documented option to:
- Keep Phone Link connected for other features, while
- Only handling calls that are manually dialed from the PC, and
- Preventing in-progress or newly started iPhone calls from moving to the PC automatically.
To avoid calls on the PC, the supported approach is to disable the Calls feature entirely in Phone Link settings, or unpair the iPhone from the PC when calls should not appear on the PC.
