Systems and methods are disclosed which allow a person to pre-set preferred calling times for receiving incoming calls. During these pre-set times (which could vary from day to day) calls that arrive are interrupted such that ringing tone is not applied to at least some of the telephones at the user's premises. The caller is informed that the user prefers not to receive calls until the pre-set time. In one embodiment, the caller is given the option of leaving a message or, if the caller desires, completing the call. The system can be implemented by a call answer machine at the customer's premises while in another embodiment the interrupt occurs at a central switching point.
