Incoming calls to a switchboard during evening and weekend hours are automatically rerouted to ring only at designated night answering phones such as the security desk.
This is most typically performed by a smart ACD system which routes calls on a particular DNIS based upon time of day. An IVR also can be attached to this DNIS which can be programmed to perform a similar function
