The simplest thing to do then may be the station lock feature. The reason I asked is i have some CORS that i have incoming calls route to an announcement after 9:00 pm. (ch time of day) (Patient rooms) so they do not get disturbed. This still lets them dial out but not receive calls.
I also think the station lock may be better in case someone stays a little late and they need to call 911. With the COR being completely cut off they can not in the event of an emergency.
