Pathfinder Number Translation Service

PathFinder ENUM Query Service

PathFinder provides a hub for discovering addressing, routing and service information for telephone numbers on a global basis.

ENUM Query Service Explained

Operator, carriers and hubs use the query service to access ENUM information held in PathFinder, ie the Tier 1 and Tier 2 data published by users of the hosting service and the Root Directory. From this common starting point, the user receives addressing information in the form of NAPTR(s) or pointers to other registries in the form of NameServer addresses. By simply submitting a number during call establishment, or message routing, via a standard ENUM query the user can access the global network of ENUM registries and NGN routing information.

Carrier ENUM enables users to discover NGN numbers, identify network capabilities and correct number portability before taking routing decisions. This is a major step forward from traditional next hop routing interconnect techniques.

Users access PathFinder through the GRX/IPX secure IP transport network using ENUM. PathFinder operates as a cloud service meaning that there are multiple query nodes distributed globally offering a low latency source close to the user.
