Support is building for ENUM (E.164 Number Mapping), according to a study conducted by Forrester Consulting for Nominum, a company that provides network naming and addressing products.

ENUM is a set of protocols used for mapping standard phone numbers to Internet domain names, which would be useful in integrating the public switched telephone network (PSTN) with IP voice services (VoIP).

The report notes that industry bodies such as the GSMA (GSM Association) and telecommunications providers globally have embraced and are adopting ENUM to solve inter-carrier routing for VoIP and next- generation services.

Not mentioned in the summary of the report is that ENUM is supported by the cable industry, as well. The protocols are included in the new PacketCable Release 2 specifications from CableLabs.

The report finds that schedules of Next Generation Network (NGN) deployments vary by operator (most deployments are in the earliest stages), but all are finding the ENUM Routing Directory function to be an important component enabling interoperability and the eventual monetizing of communications products.
