摘要: An apparatus and method are provided for routing a call to dedicated number through an AIN-based network. A predetermined sequence of preferred or ranked carriers is assigned end office from which originates. Input the at triggers system assign primary carrier connect based on user selection, local PIC, first indicated by sequence. alternate secondary may also be The routed sequentially primary, alternate, until connection made with corresponding interexchange all routes exhausted. features invention particular useful calls Government Emergency Telecommunications Service (GETS).
