Infrastructure ENUM by Geoff Huston
After much initial fanfare a couple of years ago ENUM has matured to a state where it is currently yet another under-achiever in the technology deployment stakes. ENUM initially presented itself as a very provocative response to the legacy telco position of monopolising public voice services through their exclusive control over the Public Switched Telephone Network (PSTN) and the associated controlling position over the telephone number space (the so-called “E.164” number space, after the ITU-T recommendation E.164 which recommends country code assignments for switched telephony services). The perception was that ENUM was going to dismantle these levers of control and open up the voice market to a new wave of competitive carriers. If the address plan was the key to the PSTN, then ENUM was intended unlock this network and position the new wave of VOIP carriers to take over any residual treasures of the traditional voice market.
