Claim 7:
8. A method of implementing a central routing function (CRF) platform to provide reliable call control on a call route and ensure that a call terminates effectively, comprising:
storing, in a non-transitory memory of the CRF platform, a plurality of prioritized call route lists, wherein each prioritized call route list associates the call route to a destination telephone number in a prioritized order;
receiving, by a back-to-back user agent application of the CRF platform, a request for a call route list from a network element, wherein the request comprises a destination telephone number;
obtaining, by a list generation application of the CRF platform, the call route list from the prioritized call route lists based on the destination telephone number;
attempting, by the back-to-back user agent application, to complete the call using one or more IP addresses in the call route list according to the prioritized order until the call terminates effectively; and
recording, by a key performance indicator (KPIs) collector application, one or more KPIs based on each attempt to complete the call using the one or more IP addresses,
wherein the CRF platform is implemented in part using a software container.
