Call routing using domain name service and electronic number mapping

摘要

Methods and systems for routing mobile device calls, based on a converted telephone number of a mobile device, location information of the mobile device, and trunk group identifiers. A query requesting one or more routes for a mobile device call is generated. The query includes a converted telephone number of the mobile device and location information of the mobile device. One or more responses identifying one or more routes for the mobile device call are received from a centralized routing function. The one or more responses each include an originating trunk group identifier. The originating trunk group identifier includes an egress trunk group. Upon receiving the one or more responses, the mobile device call is routed using an outbound trunk group of a response from the centralized routing function.

1. Non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, enable a computing device to perform a method of routing mobile device calls based on a converted telephone number of a mobile device, location information of the mobile device, and trunk group identifiers, the method comprising:
generating a query requesting one or more routes for a mobile device call, the query comprises the converted telephone number of the mobile device and location information of the mobile device; receiving one or more responses from a centralized routing function identifying the one or more responses each comprising an originating trunk group identifier and a terminating trunk group identifier, wherein the originating trunk group identifier includes an egress trunk group and the terminating trunk group identifier comprises an egress trunk group for a next hop tandem switch; and upon receiving the one or more responses, routing the mobile device call using an egress trunk group of a response from the centralized routing function.
