The Intel® PROSet/Wireless Software for Bluetooth® Technology does not include the Bluetooth profile required to use the PC as Headset or speakerphone for your cell phone. The options available for a connected device will depend on the capabilities of the PC, the wireless adapter and the Bluetooth device, in your configuration, you will be able to Send Files, Play Music and Synchronize Data as you mentioned before.
Please review the "Supported Features of Intel® PROSet/Wireless Software for Bluetooth® Technology" for more information about what is included in the generic driver available from Intel® Download Center.
You might want to check with your PC manufacturer (Dell) or Microsoft if they have a solution or additional software to achieve this.
The Intel® PROSet/Wireless Software for Bluetooth® Technology, for Windows 7*, is able to make use of Headsets and Hands-free devices, and integrate them to Voice over IP software, allowing the computer to work as Audio Gateway (HFP/HSP Server), however, it does not include the option to behave as the headset itself (HFP/HSP Client). This is the reason why the option seen in the video is not show in your computer when the phone is connected.
This is noted in the Supported Bluetooth profiles listed in the previous link:
- Headset Profile (HSP) (Audio Gateway)
