For some reason it doesn't work any more (I've used that at my old address with normal ADSL connection, worked fine.
Unfortunately now it doesn't work correctly with Sky Fibre Optic, it keeps dropping download speed (2-3x times), disconnecting broadband or showing that call is active while called disconnected 2 minutes ago...
Can't use it :/.
I've tried even settings from this website, unfortunately doesn't working.
I thought that maybe I am using wrong cable but actually I don't remember to use any special cable for Obi at previous address (somehow I have connected it to ADSL filter).
