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, including a processing system for performing operations for determining service requirements of a call session at first user equipment associated with a communication network, determining a first codec to facilitate the call session at the first user equipment according to the service requirements of the call session, searching a session border controller table according to the first codec to obtain a first resource identifier associated with a first session border controller type to facilitate the call session at the user equipment, receiving a first address of a first session border controller associated with the communication network from a domain name server associated with the communication network responsive to a first query including the first resource identifier, and sending a first transport protocol message to the first session border controller according to the first address. Other embodiments are disclosed.

Abstract: Methods and apparatus to achieve internetwork connectivity. Initiation is detected, by a first device on a first network, of an internet protocol (IP) connection with a second device on a second network, wherein the first network includes a plurality of egress devices that are configured to send requests for inter-network connection information. A subset of the egress devices are selected, wherein each of the subset of egress devices are configured to query for connection information relating to the second network. The subset of devices are caused to query the at least one other network for the connection information relating to the second network. The connection information is received relating to the second network. The connection information is caused to be used in establishing the IP connection between the first device and the second device.

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: In one embodiment, a method and apparatus for resolving domain name system queries using unique top-level domains in a private network space are disclosed. For example, the method determines that a domain name service query specifies a destination residing in a private network space rather than in a public Internet space. The method then routes the domain name service query to a top-level domain name service server associated with the private network space, without routing the domain name service query to a root domain name service server in the public Internet space. The top-level domain name system server resides in the highest level of a hierarchy of domain name system servers belonging to the private network space.

Abstract: In some cases, a method may include receiving information at a media device that is associated with movement of an accessory device. The accessory device is communicatively coupled to the media device via a media interface of the media device (e.g., a mini-phone jack of the media device). The method includes determining, at the media device, whether the accessory device satisfies accessory device orientation criteria based on the information. In response to determining that the accessory device does not satisfy the accessory device orientation criteria, the method includes generating a signal. The signal may be communicated from the media device to the accessory device via the media interface. In some cases, the signal may include accessory device re-orientation information.
