Abstract
Service subscriber inbound call control is effected from within a public switched telephone network (PSTN) using a Call Service Node (CSN). On receipt of a call directed to the service subscriber, at least one messaging network message is sent to the service subscriber to request a call treatment option. Pending receipt of a reply from the subscriber, the call is routed by the CSN to a call parking facility in the PSTN. The call parking facility may be a voice mail box of the subscriber or an announcement facility. After a call treatment option is received, the call is released from the call parking facility the call treatment is effected. The service enables single number service for multiple service subscriber directory numbers, unified voice mail for multiple service subscriber telephone numbers, or segregated voice mail boxes for a single service subscriber number, as well as real-time, interactive inbound call screening.
