Enabling Internet Protocol Carrier Peering to Foreign Network Domains

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.

         2 . The method of  claim 1 , wherein the private enabled telephone number mapping server is associated with the originating carrier network. 
     
     
         3 . The method of  claim 1 , wherein the private enabled telephone number mapping server is accessible only to devices within the originating carrier network. 
     
     
         4 . The method of  claim 1 , wherein the name authority pointer record placeholder instructs the private enabled telephone number mapping server to generate a unique enabled telephone number mapping response message in response to receiving a private enabled telephone number mapping query that provides a telephone number to place an internet protocol call to the receiving carrier network. 
     
     
         5 . The method of  claim 4 , wherein the name authority pointer record placeholder comprises a placeholder domain. 
     
     
         6 . The method of  claim 5 , wherein the placeholder domain can be appended to the telephone number to form a dynamic session internet protocol uniform resource identifier. 
     
     
         7 . The method of  claim 4 , wherein the unique enabled telephone number mapping response message directs the originating carrier network to access an external domain table. 
     
     
         8 . A computer system comprising:
 a processor; and   a memory that stores computer-executable instructions that, when executed by the processor, cause the processor to perform operations comprising
 identifying a plurality of numbering plan area identifiers corresponding to a receiving carrier network, wherein the computer system executes within an originating carrier network, and wherein the originating carrier network is associated with a domestic carrier and the receiving carrier network is associated with a foreign carrier 
 accessing a plurality of numbering plan area zone file records corresponding to the plurality of numbering plan area identifiers, wherein the plurality of numbering plan area zone file records are stored on a private enabled telephone number mapping server, and wherein at least a portion of the plurality of numbering plan area zone file records comprises a plurality of name authority pointer records, 
 creating 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, and 
 replacing the plurality of name authority pointer records with the single instance of the name authority pointer record placeholder. 
   
     
     
         9 . The computer system of  claim 8 , wherein the private enabled telephone number mapping server is associated with the originating carrier network. 
     
     
         10 . The computer system of  claim 8 , wherein the private enabled telephone number mapping server is accessible only to devices within the originating carrier network. 
     
     
         11 . The computer system of  claim 8 , wherein the name authority pointer record placeholder instructs the private enabled telephone number mapping server to generate a unique enabled telephone number mapping response message in response to receiving a private enabled telephone number mapping query that provides a telephone number to place an internet protocol call to the receiving carrier network. 
     
     
         12 . The computer system of  claim 11 , wherein the name authority pointer record placeholder comprises a placeholder domain. 
     
     
         13 . The computer system of  claim 12 , wherein the placeholder domain can be appended to the telephone number to form a dynamic session internet protocol uniform resource identifier. 
     
     
         14 . The computer system of  claim 11 , wherein the unique enabled telephone number mapping response message directs the originating carrier network to access an external domain table. 
     
     
         15 . A computer storage medium having computer-executable instructions stored thereon that, in response to execution by a processor of a computer system, cause the processor to perform operations comprising:
 identifying a plurality of numbering plan area identifiers corresponding to a receiving carrier network, wherein the computer system executes within an originating carrier network, and wherein the originating carrier network is associated with a domestic carrier and the receiving carrier network is associated with a foreign carrier;   accessing a plurality of numbering plan area zone file records corresponding to the plurality of numbering plan area identifiers, wherein the plurality of numbering plan area zone file records are stored on a private enabled telephone number mapping server, and wherein at least a portion of the plurality of numbering plan area zone file records comprises a plurality of name authority pointer records,   creating 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; and   replacing the plurality of name authority pointer records with the single instance of the name authority pointer record placeholder.   
     
     
         16 . The computer storage medium of  claim 15 , wherein the private enabled telephone number mapping server is associated with the originating carrier network. 
     
     
         17 . The computer storage medium of  claim 15 , wherein the private enabled telephone number mapping server is accessible only to devices within the originating carrier network. 
     
     
         18 . The computer storage medium of  claim 15 , wherein the name authority pointer record placeholder instructs the private enabled telephone number mapping server to generate a unique enabled telephone number mapping response message in response to receiving a private enabled telephone number mapping query that provides a telephone number to place an internet protocol call to the receiving carrier network. 
     
     
         19 . The computer storage medium of  claim 18 , wherein the name authority pointer record placeholder comprises a placeholder domain, and wherein the placeholder domain can be appended to the telephone number to form a dynamic session internet protocol uniform resource identifier.
