A customized routing service platform for routing international communications includes a receiver that receives, from an international gateway via a network node, international communication origination data for an international communication to a customer's communication address. A database server receives customer routing instructions from the customer via a web server. The database server stores the received customer routing instructions. The database server also retrieves stored customer routing instructions, and determines a destination communication address based on the international communication origination data and the retrieved customer routing instructions. A forwarder forwards the destination communication address to the network node for routing the international communication to the destination communication address.
