Abstract
A system and method for providing advanced voice services to subscribers of a telecommunications network are disclosed. The system comprises a local switch connected to the telecommunications network for providing two-way communication between the subscribers and the network. A database of subscriber services, which may be a virtual service switching point (ViSSP), is connected to the local switch, and an intelligent peripheral (IP) is connected to the database and the local switch. The IP processes voice information and dual tone multi-frequency (DTMF) digits received from the switch in response to instructions from the database. The system retrieves subscriber services from the database utilizing a call-setup protocol such as the Integrated Services Digital Network (ISDN) User Part (ISUP) call setup protocol, and provides the services to the switch. The system also retrieves the processed voice information and DTMF digits from the IP and provides the processed information and digits to the switch.
