As Internet based Voice-over-IP services continue to improve in quality and user acceptability, the need for practical interconnection between the legacy PSTN network and the new IP environment increases. ENUM, as a protocol, was developed to help PSTN users access users of IP devices. But ENUM is also a service, and companies are jockeying for position in the hope of making big profits.
