  • Patent number: 7466800
    Abstract: A system and method for voice activated dialing (VAD) using an intelligent peripheral (IP), such as a service circuit node (SCN) in an Advanced Intelligent Network (AIN). This invention preserves subscriber preferences for certain attributes including preferred interexchange carrier (PIC) and billing information, without the need for data replication within either the IP or the service switching point (SSP) hosting the IP. Additionally, call routing within the network is optimized and the need for double trunking is eliminated because the IP drops the call back to the originating SSP, from which the call is then routed.
