US 11,888,598 B1 · Central routing function (CRF) implementation on a call route

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.

Dependent claims

A central routing function (CRF) platform, comprising:

at least one processor;
a non-transitory memory communicatively coupled to the at least one processor that stores a plurality of prioritized call route lists;
a back-to-back user agent application stored in the non-transitory memory that, when executed by the processor, receives a request for a call route list from a network element, wherein the request comprises a destination telephone number;
a list generation application stored in the non-transitory memory that, when executed by the processor, 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, and
a pseudo domain name server (DNS) application stored in the non-transitory memory that, when executed by the processor, translates each address in the call route list into an Internet Protocol (IP) address, and
wherein the back-to-back user agent application, when executed by the processor, attempts to terminate a call using the IP address in the call route list, and
wherein the CRF platform is implemented in a software container.

4 more elements

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.
