Customer needs a 3rd mode. Holiday, DAY2 and NIGHT2 won't cut it. Here is what the customer wants:

From 8am to 5pm, ring x100, x101, x102, x103, x104, x105 simultaneously. From 5pm to 9pm, ring x110, x111, x112, x113, x114 simultaneously. From 9pm to 8am, play ID1 greeting.

Since 3 modes are out of the picture, what can we do?

Thanks,
Kevin
