Public ENUM & VoIP Peering Bi-Lateral / multi-lateral, private trees will only scale so far before operational and management challenges present themselves. Thus, Public ENUM is a long-term goal. What form will this take? (Carrier or User ENUM) Without carriers in e164.arpa is the business model for “User” sustainable? Will there be a mix of different peering types? Private POPs, with committed capacity. Public peering points. Over the Internet generally, best effort (no QoS). Bottom line: Working towards public ENUM in the future (very important), while hedging our bets with work on private ENUM in the shorter term. |
