Our system has a message that plays when the office is closed and tells the caller how to call the Answering Service. The problem is that people keep dialing "0" in hopes that someone will answer the Front desk phones when we are closed, thus bypassing the message. I am looking for a way to disable people from Dialing "0" after hours and making them listen to the message. I would be open to changing it to an extension such as our cancellation line. If anyone has any knowledge of how to do this I would be greatly appreciative.
