"I have dig.telephone 4412D+" - OK, it's a Magix?
"button 1,2,3 is ext 742" - these are the System Access buttons for the extension itself, and it happens to be Ext. 742?
"button 4 brd.ext 738" - Bridged Extension 738? Do you mean a Coverage Button for Ext. 738?
"but when you call 738,this line don't ring" - The Coverage Button for 738 is set to No Ring?
