Method and apparatus for provisioning a scalable communications network

摘要

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.

主权项

1. A method, comprising:
receiving, by a first directory server of a first regional call processing system, a new name authority pointer associated with a telephone number and comprising an internet protocol address for establishing communications with a communication device associated with the telephone number; determining, by the first directory server, whether the new name authority pointer is within a first geographic region of the first regional call processing system based on a numbering plan area code of the telephone number; storing, by the first directory server, the new name authority pointer at a first directory responsive to determining that the telephone number is located within the first geographic region; transmitting, by the first directory server, the new name authority pointer to a second directory server of a second regional call processing system responsive to determining that the telephone number is not located within the first geographic region, wherein the second directory server is accessible by a second name server of the second regional call processing system for provisioning the new name authority pointer to the second name server; receiving a version number of the new name authority pointer; determining whether the new name authority pointer is current based on the version number; and synchronizing, by the first directory server, the first directory and a first replicate directory of a third directory server of the first regional call processing system.
