A central routing function (CRF) platform. The CRF platform comprises at least one processor; a non-transitory memory communicatively coupled to the at least one processor that stores a plurality of prioritized international call route lists where each prioritized international call route list associates alternative international communication service carrier routes in a prioritized order with an international telephone number; and a call process application stored in the non-transitory memory that, when executed by the processor, receives a request for a prioritized international call route list from a network element, where the request comprises an international telephone number, pads out the international telephone number received from the network element to form a 15-digit number, looks up a prioritized international route list using the 15-digit number in the non-transitory memory, and sends the prioritized international route list to the network element.

International call route generation based on analyzing minutes of use key performance indicators (KPIs) associated with an international communication service carrier

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.

Central routing function (CRF) implementation on a call route

International call route generation based on analyzing minutes of use key performance indicators (KPIS) associated with an international communication service carrier

A method of providing prioritized call route lists to network elements of communication service carriers. The method comprises building prioritized route lists by a centralized routing function (CRF) platform by processing prioritized route list transactions built by a route generation application based on key performance indicators, receiving a request for a prioritized route list by the CRF platform from a session border controller (SBC) controlled by the first communication service carrier, where the request comprises an identity of a second communication service carrier and a destination telephone number, determining a subscriber service level associated with the second communication service carrier by the CRF platform, based on the determined subscriber service level, looking up a prioritized route list by the CRF platform based on the destination telephone number, and sending the looked up prioritized route list by the CRF platform to the SBC.

Call route generation for other communication service carriers as a service

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.

Domestic long-distance call route generation

A route manager queries a new network element to identify egress routes coupled to the network element and to identify external nodes coupled to the egress routes. The route manager queries a database with identifiers for the external nodes to identify associated telephone numbers. For each telephone number associated with an external node, the route manager associates the telephone number with the egress routes coupled to the external node and with the new network element. The route manager receives a call request to one of the telephone numbers, and in response, selects the new network element and one of the egress routes associated with the telephone number.

Emergency route control for a communication network

A route manager queries network elements to identify egress routes and external nodes coupled to the network elements. The route manager queries a database to identify telephone numbers associated with the external nodes. For each telephone number associated with an external node, the route manager associates the telephone number with the egress routes coupled to the external node and with the network elements coupled to the egress routes. On a call, the route manager selects one of the network elements and the egress routes associated with the telephone number.
