GSMA Carrier ENUM Root Directory Service
Operators, Carriers and Hubs query the GSMA’s ENUM Tier 0 Root Directory to find authoritative sources of Carrier ENUM routing information distributed around the world. The ENUM Root Directory is offered free to the industry.
Tier 0 Service Explained
GSMA works to recognise national Tier 1 Carrier ENUM registries around the world that contain authoritative and reliable ENUM data. The address of these registries is stored behind the relevant country code in PathFinder. PathFinder returns the Tier 1 registry address in the form of a NameServer address when a number with that country code is submitted in a query.
Thus the Tier 0 provides a starting point for resolving information about numbers and using standard DNS delegation techniques provides referrals to another database where more information can be found. This allows number resolution to be fully automated for the querying party saving time and money on both data acquisition and maintenance. Use cases.
Quick Start
If a country does not have a Tier 1 registry, PathFinder offers the opportunity for you to place your numbers in the root and create a partial Tier 1, becoming linked to, and discoverable by, the GSMA Carrier ENUM community. See Tier 1 hosting solutions.
