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