Brazil uses different caller id systems with different providers in different parts of the country. I even had the sytem used change after a power failure!. Try using the Swedish selection, if that does not work, try the others. There are caller id sytem converters that you can find on the internet , that will convert form one caller id method to the others in both directions, i found one on ebay for about $25. However, i think one of the caller id settings on the obi should work for you. Larry
