A system for restricting telephone calls that originate from a facility includes at least one facility resident telephone configured to originate and present a call signal, a switching office, and a destination telephone. The at least one facility resident telephone, the switching office, and the destination telephone are electrically serially coupled such that a call signal originating at the at least one facility resident telephone is routed to the destination telephone via the switching office. The switching office disables at least one custom calling feature corresponding to the call signal upon determining the call signal as originating from the at least one facility resident telephone.
