Abstract

A central routing function (CRF) platform. The CRF platform comprises a processor, a memory that stores prioritized call route lists, and an application stored in the memory. When executed by the processor the application receives a request for a prioritized call route list from a network element, where the request comprises an indication of a location of a call originator of a call and a destination telephone number, determines a call type of the call, selects a prioritized call route list associated with the destination telephone number from the non-transitory memory based on the call type, determines that a percent allocation rule applies to the call, based on the percent allocation rule, removes the first priority call route from the selected prioritized call route list to make an adapted prioritized call route list, and sends the adapted prioritized call route list to the network element.
