Abstract
A system and method for providing call information query stores modified call information associated with a telephone number within the local databases of a service provider's local network. The modified call information enables a service provider to unilaterally alter how calls are routed and rated. The service switching points (SSPs) located within a same local network are equipped with modified intelligent network or advanced intelligent network software that enables the local SSPs to receive remote call information resulting from a remote query performed by a remote SSP. The local SSPs analyze the remote call information and generate queries to their local databases to obtain modified call information. New services requiring modified call information can then be implemented based upon the modified call information received as a result of the queries.
