Abstract: An aspect of the subject disclosure may include, for example, receiving a request from a communication device to initiate a communication session in a packet-switched network, obtaining a first name authority pointer record responsive to determining that there is an undesirable operational state in the packet-switched network, wherein the first name authority pointer record comprises a null record, obtaining a second name authority pointer record responsive to determining that there is a desirable operational state in the packet-switched network, wherein the second name authority pointer record comprises a record, and initiating the communication session according to one of the first name authority pointer record or the second name authority pointer record. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a method and system to interconnect a first communications carrier to a second communications carrier by receiving a request to connect a communication from a first carrier to a second carrier; modifying a private ENUM (tElephone NUmber Mapping) domain of the request to include an intercarrier ENUM apex based domain; retrieving a routing record using a domain name server (DNS) indicated by the intercarrier ENUM apex based domain; and routing the communication to the second carrier using the routing record. Other embodiments are disclosed.
