Apparatus and methods for a scalable communications network

A device, comprising:

• a memory storing computer instructions;
• and
• a processor coupled to the memory, wherein the processor responsive to executing the computer instructions performs operations comprising:
• determining whether a telephone number is located in a first geographic region of a plurality of geographic regions of a telephone system responsive to receiving a first request for a name authority pointer associated with the telephone number;
• identifying a first in-region name server that is associated with the first geographic region responsive to determining that the telephone number is located in the first region;
• the first in-region name that is identified;
• receiving the name authority pointer from the first in-region name server responsive to transmitting the second request;
• identifying a second geographic region of the plurality of geographic regions that is associated with the telephone number responsive to determining that the telephone number is not located in the first geographic region;
• identifying a first out-of-region name server that is associated with the second geographic region that is identified, wherein the first out-of-region name server is not associated with the first geographic region;
• transmitting a third request for the name authority pointer to the first out-of-region name server that is identified, wherein the third request is transmitted to the first out-of-region name server according to a determination by a load balancer that a second out-of-region name server is not available;
• and
• receiving the name authority pointer from the first out-of-region name server responsive to transmitting the third request.

A non-transitory computer-readable storage medium, comprising computer instructions, which when executed by a processor, cause the processor to perform operations comprising:

• determining whether a telephone number is located in a first geographic region of a plurality of geographic regions of a telephone system responsive to receiving a first request for a name authority pointer associated with the telephone number;
• identifying a first in-region name server that is associated with the first geographic region responsive to determining that the telephone number is located in the first region;
• second request for a name authority pointer to the first in-region name server that is identified;
• receiving the name authority pointer from the first in-region name server responsive to transmitting the second request;
• identifying a second geographic region of the plurality of geographic regions that is associated with the telephone number responsive to determining that the telephone number is not located in the first geographic region;
• identifying a first out-of-region name server that is associated with the second geographic region that is identified, wherein the first out-of-region name server is not associated with the first geographic region;
• third request for the name authority pointer to the first out-of-region name server that is identified, wherein the third request is transmitted to the first out-of-region name server according to a determination by a load balancer that a second out-of-region name server is not available;
• and
• receiving the name authority pointer from one of the in-region name server or the first out-of-region server.
