What is Private Infrastructure ENUM?
Private ENUM uses the concepts of creating a domain name from a telephone number (TN) and resolving it to a URI. It does not, however, use the domain e164.arpa (or any other domain with regulatory oversight). Private ENUM is used when there is a closed user group that wants to use ENUM to exchange IP traffic. An example of such a user group is a group of communications carriers that wants to exchange VoIP traffic. The user group that creates and uses the domain will also create the policies for the domain. There will be no regulatory oversight of this domain, because it is not intended for public use.
