VoIP Gets a New P2P Routing Protocol (DUNDi)

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.

  1. Another great move by salemnic · · Score: 5, Informative

    * 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!

    What do we need this for? Don't we have enough protocols?

    This is actually pretty cool from a distributed PBX perspective. I am not sure I would want to use it over the internet with untrusted PBX's but it would be pretty useful inside a large corporate structure.

    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.

    This new protocol is not for peer to peer voice communication. It's a method like a phone book. So you ask your peers if they know how to contact person X, your peers contact their peers and so on until they find the address of a person (for example the IAX/SIP/OpenH.323 address). Then the address is passed back though the peers to the original person doing the lookup, and is cached along the way.

    You then make your telephone call using VOIP. The IAX (Inter Asterisk Exchange) protocol is amazing at getting though NAT'd connections etc. It can even trunk lots of calls together into one packet.

    So in a nutshell, this is like a p2p enum.
