In the dial plan, with GotoIf...is there a way to do a logical negation(NOT)? I want to check if the year is a leap year and the below code is how I would write the check in C. According to the wiki there isn't a logical NOT as a valid expression. From reading the asterisk/docs/README.variables, this seems to be missing. int year = 2005; if ( (year % 4 = 0) && !(year % 100 = 0) && (year % 400 = 0) ) { leapyear = true; } --johann
