Hi,I want to customize the phone format number, just before it is sent to the database. Indeed, I want to add international prefixes (+49, etc…) to telephone numbers, each time they are inputted.For example, 015417543010 > 4915417543010.After reading some piece of code, I understand that ./include/class.format.php is the file to modify. Am I wrong?So I tried to put some logic in function phone, between lines 90-99, but it does not work at all. It is as if the function was never called. I can even remove function phone completely, and yet, osTicket works as if nothing has been changed…Here a simple example that does do nothing: function phone($phone) { $phone= preg_replace('/^0/', "49", $phone); return $phone; }Thanks for any help.
