how to create a progrematically call

Question

hi

im trying to implement a "support" button that should make a call while press it, does someone can help find the correct API??

i cant find how to implement this button to make the call, i already set a field listener for those buttons, one should call support and the other should connect me to a web address.

            mymenuitem item1 = new mymenuitem( "Call vm",3,2 );
            addMenuItem(item1);

            mymenuitem item2 = new mymenuitem ( "help",2,1);
            addMenuItem(item2);

thanks!
