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: 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: 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.

Abstract: A method that incorporates teachings of the subject disclosure may include, for example, determining at a first directory server of a first regional call processing system whether a new name authority pointer associated with a telephone number is within a first geographic region of the first regional call processing system, transmitting the new name authority pointer to a first name server of the first regional call processing system for provisioning the name authority pointer to the first name server responsive to determining that the telephone number is located within the first geographic region, and transmitting the new name authority pointer to a second directory server for provisioning the new name authority pointer to a second name server of a second regional call processing system responsive to determining that the telephone number is not located within the first geographic region. 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: A system that incorporates teachings of the present disclosure may include, for example, receiving a request for a voice call at a mobile switching center server, transmitting a mapping query from the mobile switching center server to a database in response to the request for the voice call, route the request from the mobile switching center server to an internet protocol multimedia subsystem for facilitating establishing the voice call when the mapping query is successful in obtaining an internet protocol address for establishing the voice call with a recipient communication device, and routing the request from the mobile switching center server to a second server for facilitating establishing the voice call without routing the request to the internet protocol multimedia subsystem when the mapping query is not successful in obtaining the internet protocol address. Other embodiments are disclosed.
