Distributed Universal Number Discovery

DUNDi is a peer to peer system for locating Internet gateways to telephony services. Unlike traditional centralized services (such as the remarkably simple and concise ENUM standard), DUNDi is fully distributed with no centralized authority whatsoever.

DUNDi is not itself a Voice over IP signalling or media protocol. Instead, it publishes routes which are in turn accessed via industry standard protocols such as IAX, SIP and H.323.
