Ip carrier peering with dns recursion zone

A method to interconnect a first communications carrier to a second communications carrier, the method comprising:

• receiving a request to connect an IP (Internet protocol) communication from equipment of the first communications carrier to equipment of the second communications carrier;
• querying, using a first query, a private ENUM (tElephone NUmber Mapping) of the first communications carrier;
• modifying the first query to include an intercarrier ENUM apex-based domain with a DNS (domain name server) recursion zone, wherein the DNS recursion zone includes at least a primary internet address of a tier 2 ENUM of the second communications carrier;
• automatically forwarding the query that is modified to the equipment of the second communications carrier to retrieve a routing record from the second communications carrier;
• and
• routing the IP communication to the equipment of the second communications carrier using the routing record.

A communication processing device comprises:

• an interface;
• a memory;
• and
• a processing unit operably coupled to the interface and the memory, wherein the processing unit functions to:
• receive a request to connect an IP (Internet protocol) communication from equipment of a first carrier to equipment of a second carrier;
• query, using a first query, a private ENUM (tElephone NUmber Mapping) of the first carrier;
• when the first query does not return a routing record to complete the request, create a second query with an intercarrier ENUM apex-based domain with a DNS (domain name server) recursion zone;
• automatically forward the second query to the equipment of the second carrier to retrieve the routing record from the second carrier;
• and
• route the IP communication to the equipment of the second carrier using the routing record.
