It should. Voltage and phone system are the same. However:
- an adapter for the power plug is needed
- an adapter for the phone plug is needed (both he can get from let's say conrad.de)
- Some features might not work such as CLIP
But all basic features should work (as long as it's an analog line with an analog phone). I have an old UK phone (non B&O though), and it works.
