Abstract: A system that incorporates teachings of the present disclosure may include, for example, a method at a gateway device that registers at least one mobile phone number with the gateway device via a femtocell integrated with the gateway device when a mobile device associated with the at least one mobile phone number is within range of the femtocell, registers at least one voice over internet protocol phone number with the gateway device, and selectively receives and makes calls using one of a set top box registered with the gateway device, the mobile device registered with the femtocell, a voice over internet protocol phone corresponding to the at least one voice over internet protocol phone number. 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; filtering the request to identify a specific name authority pointer (NPA-NXX) number from a plurality of specific name authority pointer (NPA-NXX) numbers; when the filter identifies the specific name authority pointer (NPA-NXX) number, modifying a private ENUM (tElephone NUmber Mapping) domain of the request to include an intercarrier ENUM apex based domain with a DNS (domain name server) recursion zone; 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.

Abstract: Methods and systems may provide carrier ENUM based routing for subscriber devices (e.g., voice or other multimedia services over IP) to locate and to connect to subscriber devices of another IP peering carrier. A private ENUM database may be used to connect subscribers of disparate carriers using a domain for designated breakout gateway control functions.

Abstract: Concepts and technologies pertaining to enabling internet protocol carrier peering to foreign network domains are provided. A method includes identifying, by a computer system executing within an originating carrier network, a plurality of numbering plan area identifiers corresponding to a receiving carrier network. The method further includes accessing, by the computer system executing within the originating carrier network based on the plurality of numbering plan area identifiers, a plurality of numbering plan area zone file records stored on a private enabled telephone number mapping server. The method also includes creating, by the computer system executing within the originating carrier network, a single instance of a name authority pointer record placeholder within each of the plurality of numbering plan area zone file records stored on the private enabled telephone number mapping server.

Abstract: Aspects of the subject disclosure may include, for example, responsive to determining that a second device is associated with a first carrier network, obtaining a first record associated with a called number of the second device from a first carrier network telephone number mapping equipment server of the first carrier network, and transmitting a first internet protocol address for the second device from the first record to a terminating call session control function server of the first carrier network to initiate the internet protocol call session. Responsive to a second determination that the second device is associated with a second carrier network, obtaining a second record associated with the called number according to a pointer to a second carrier network telephone number mapping equipment server of the second carrier network, and transmitting a second internet protocol address for the second device derived from the second record to a session border controller of the first carrier network to initiate the internet protocol call session. Other embodiments are disclosed.
