$('.contacts-tel-reg-item').on('click',function () {
        var get_code = $(this).attr('data-mask-phone');
        var get_flag = $(this).children('.contacts-tel-reg-item--flag').attr('style');

        $('.contacts-tel-reg--flag').attr('style',get_flag);
        $(this).parents('.contacts-tel-reg--wrap').next('.mask-phone').mask(get_code);

    });
