The United States, France, Spain and Argentina advanced to the Davis Cup finals while Belgium beat hosts Finland 3-2 in the qualifiers on Saturday.
Australia came from behind to beat Hungary 3-2 in Sydney.
The 12 winners on Saturday will advance to World Group I of the Davis Cup final in mid-September, joining 2021 runners-up Croatia and Britain and Serbia. It remains to be determined the replacement of the 2021 champion, Russia, excluded this week after the invasion of Ukraine by this country.
The top eight from there will go to the final at the end of November.
