Hello.
I can pair devices successfully and even transfer files back and forth using "send over Bluetooth" feature.
What i cannot do is to answer calls using headphones with microphone, plugged into notebook.
I had that working with my previous HP notebook, with BroadCom BT chip, so it hardly a phone issue.
Also i could play music on my mobile and it was playing over BT to HP notebook headphones too.
I suspect that it is a hardware or drivers issue or lack of feature of built into notebook Intel's BT adapter, but i need a confirmation or help to get it working.
Before you suggest that, i did look into "Services" tab of Phone's properties, and there is COM-ports only.
When i check it on the previous notebook, there is much more services like ".. Audio gateway" and some similar.
I have freshly installed Windows 10 (Clean install) and recent Intel's BT driver. I've also tried with MS installed stock driver and with MSI provided driver - no difference.
BT Model: Intel(R) Dual Band Wireless-AC 3165
Driver Version: Intel(R) Wireless Bluetooth(R) , 19.00.1621.3340
Windows 10 Pro, up-to-date.
