Not much of a chance that someone'll answer, the ringing can't be heard outside the box. But I think it's a good contribution to the site as the payphone has loads of character and the building it stands before has a strange attribute. It's called the lighthouse and is now derelict, nobody knows who built it and when. Now that is strange for central London.
