Will this device support using 220v electricity like used in the EU?

Yes the power adapter is 110-240V

Can I use a fax machine with it to send faxes?

No fax does not work. The cell phone network blocks fox and modem signals.

This unit will work with my antique phone but when the bluetooth is on in order for this to work I can't use my cell phone

You can easily temporarily disconnect Bluetooth on your cell phone and then use the cell phone. On my android, I just touch the button on my call screen.

I can trigger google assistant (pixel 7) via my bt2 but subsequent audio input/output doesn't go through the old phone. is that fixed on the bt hd?

I don't know. I have a Google 6 and it appears towork fine
