VoIP Gets a New P2P Routing Protocol (DUNDi)

Posted by michael on from the transylvania-6-5000 dept.

bkw.org writes "Today Digium released DUNDi which can be used with the Asterisk Open Source PBX for p2p call routing. Digum has also released a whitepaper (pdf) on DUNDi so others can implement this new technology into their products and give VoIP a push into the mainstream." Voxilla also has a story.

    Great, Now I can get telemarketers trying to enlarge my bank software in nigeria, and viruses on my VOIP line and in my e-mail

    * is awesome, and for anyone who hasn't given it a shot, I definitely recommend it. Digium even sells some FXS/FXO cards if you want it to replace your traditional in-house system.

    Something neat for every geek!

    DUNDi stands for "Distributed Universal Number Discovery". It is a peer to peer system for locating Internet gateways to telephony services. Unlike traditional centralized services (such as ENUM), DUNDi is fully distributed, with no central authority. DUNDi is not a Voice over IP signalling or media protocol: it publishes routes which are in turn accessed via industry standard protocols such as IAX, SIP and H.323.

    The above information is taken (with minor edits) from the dundi.com website. It's the sort of information that would have been useful in the executive summary, IMHO.

    Well, look at things this way: ENUM has been around for *years*, yet there's still no official ENUM tree. There's no way for VoIP carriers like Vonage to publish SIP addresses for the PSTN numbers that they service.

    Why? Because of political squabbling by telcos, verisign, and the like. Whoever controls the ENUM tree will be able to control the future of telecommunications. That means money and power, and that's why there's no progress occuring--all of the usual players are jockeying for position, and will be for years.

    Since ENUM is really just a DNS tree, that hasn't stopped people from producing their own ENUM trees (e164.org, etc), but there's nothing particularly official about any of them. They're all interim solutions, and none of them are big enough to be able to make a difference on their own.

    There are a couple differences with DUNDi. First, it's *designed* to be decentralized, without a single point of control (or toll collection). There's an open-source implementation right out of the gate. It at least pays lip service to spam and telemarketing issues. As long as you sign the agreement, it *should* be possible for anyone to participate. And, it already has several mid-sized providers involved.

    In short, right out of the gate, DUNDi is already ahead of ENUM, because it's already usable, while ENUM still doesn't have any way to publish numbers in the "official" e164.arpa tree. DUNDi doesn't have room for Verisign-style toll collection, while the official ENUM tree almost requires it.

    We'll see how it goes. If Vonage joins up, then DUNDi has probably won and ENUM will end up being irrelevant, because the network effect will strongly favor DUNDi.
