A public switched telephone system with an intelligent network (IN) for automated call processing is compatible with Call Waiting service. Unlike prior art systems in which a customer placing a call handled by an IN must disable Call Waiting service during an entire transaction (initial call placement, connection to the destination and conversation until the parties "hang up") to avoid non-processing or mis- processing by the IN, a customer using the present invention need only disable Call Waiting when communicating with an Intelligent Peripheral during the initial call placement. The system automatically restores Call Waiting after the call has been routed so that the feature is available during a telephone conversation.
