Abstract
A central routing function (CRF) comprises back-to-back user agent application that receives a request for a call route list from a network element, wherein the request comprises a destination telephone number, a list generation application that obtains the call route list from the prioritized call route lists stored in the non-transitory memory based on the destination telephone number, wherein the call route list comprises a plurality of addresses, a pseudo domain name service (DNS) application that translates each address in the call route list into an Internet Protocol (IP) address, in which the back-to-back user agent application attempts to terminate a call using the IP address in the call route list, and in which the CRF platform is implemented in a software container.
