Michael Robertson Talks VoIP With Voxilla

Vick writes "Two 'Bad Boys' of internet audio, MP3.com's Michael Robertson and Kazaa's Niklas Zenstrom, are done taking on the recording industry. Now their big fight is with the telephone companies and, apparently, one another. In one corner is Zenstrom's Skype, a software-only VoIP product that uses its own protocol and is banking on the huge popularity of Kazaa for its success. In the other corner is Robertson's SIPPhone.com, trying to simplify VoIP, and using the standard SIP protocol, to try to bring internet telephony to the masses. In this Voxilla.com interview, Robertson talks about the future of VoIP and minces no words in explaining why Zenstrom and the Kazaa boys have got it all wrong." (Last month, we posted about Skype.)

      SIP is a P2P standard. It pretty much follows the IETF party line of "Lobotomized Core, Smart Edge" in design -- all the intelligence in SIP call handling is supposed to be at the end points, handled by the peers. It tries very hard to make the network itself brain dead.

      It gets fuzzy around the REGISTER/location servers -- until every ISP has a SIP REGISTER/location server per domain name and/or hostname, SIP users are going to need some place to go where they can look up and find each others' network information/location data so they can place calls to one another. So at the moment, that's tending to push a centralized REGISTER/location server from the current VoIP providers.

      There are a host of issues with running VoIP in a P2P model. NAT traversal being just one of them. Another is the authentication/authorization problem -- SIP was at once point locked in endless arguments about IPSec vs. TLS, certificate management among all the end points, key management, etc.

    VOXILLA.COM Staff Report

    It says a lot about the future of internet telephony that two of the most successful bad boys of the internet - Kazaas Niklas Zenstrom and MP3.coms Michael Robertson - have turned their attention to promoting the growth of Voice over IP.

    Both Zenstrom and Robertson incurred the ire of the music industry and the Recording Institute Association of America because the technologies they helped establish made it much easier to download copyrighted music over the net. Robertson came first by helping to make the MP3 compression format the ubiquitous standard for audio on the net. Zenstrom followed by releasing Kazaa, which quickly became the most popular P2P program used by music sharers around the world.

    Now the pair are slashing away at a whole different breed of industry titan: the giant telephone companies. But, though they share a common adversary, they have chosen to fight their new battles in entirely different ways.

    Zenstrom is hoping to bring the telephone giants to their knees with Skype, an IP-to-IP VoIP software program that currently works only in Microsoft Windows and utilizes a proprietary protocol to establish voice connections between its users. Banking on the popularity of Kazaa, Zenstrom says more than 1.2 million users worldwide have downloaded Skype.

    Robertson, on the other hand, has chosen a totally different route. His SIPPhone.com provides users with two telephones for less than $130. The SIPPhones, manufactured by Grandstream, connect to an Ethernet port and utilize the SIP protocol, which is quickly becoming the de facto standard for IP-to-IP voice communications.

    Robertson is hoping that SIP becomes as widespread as MP3, and believes SIPPhone will help carry it a large portion of the way there.

    In a way, Robertson is trying to do with SIP what he did for MP3 and later with Linux with his still-kicking Lindows operating system: Take a technology that works well but is understood only by the geekiest of computer users, simplify it to its most basic form, and market it to typical consumers directly.

    Robertson still does not know how his new company will ever make a profit. His goal is to make it available to millions of users and go from there. Having sold MP3.com to Vivendi for more than $370 million in 2001, he can probably take his time to get there.

    We caught up with Robertson during VON 2003 in Boston last month. Heres our conversation:

    Voxilla: The SIPPhone has been out for nearly two months. So whos signing up?

    Michael Robertson: I would say that probably the number 1 feedback we get is that its from international users. Theyll get two phones, theyll try them out and then theyll email us with Hey, Im ordering two more because I have a friend, or a co-worker, or an office in, fill in the foreign country here, India, China, Mexico.

Microsoft Netmeeting supports it for video as well as audio. If you just want to connect two things together, H.323 will work fine, but if you want to build any sort of complex system, it's pretty clumsy. If you want to connect two new fancy systems together, and they're not really compatible, they'll often fall back to H.323.
    • SIP is the main new standard, and everybody says they're going to use it Real Soon Now (particularly the VOIP router and PBX folks), though many of them don't actually have it implemented on all of their products yet because they've got too much embedded base. SIP is a much simpler and cleaner protocol, which looks like something written by Internet Unix developers who weren't worried about their embedded base of ISDN telco code.
    • The extra half is "Skinny", Cisco's proprietary protocol that most of their IP PBXs and IP phones use, developed before SIP was sufficiently standardized. H.323 was too much baggage, though most of that equipment can fall back to it, and most of it will handle SIP Real Soon Now.
    • Yes, Skype is proprietary and closed. Too bad, because it seems to be trying some interesting approaches to user interaction and directory service.

It turns out that many of the VOIP hardware makers are really happy to fund open standards development so there's something for their equipment to talk to, whether they make voice cards for PCs (either single-user or small PBX cards), or IP PBXs that want more features to make them interesting to users, or boxes that provide some glue function, or whatever, and even Cisco is funding some of them, and some of the little software companies are happy to do open standards work as part of consulting to the hardware people.

    New PBXs are pretty much all migrating to IP-based; it's much easier to reuse low-cost PC hardware platforms and build good tools that way. The big PBX makers are generally taking their old PBXs and adding IP features on the side (as opposed to the big router makers adding VOIP boards to connect to old PBXs and telcos), and the real question for most of their customers is when to rip out the old stuff and replace it (for new buildings that need PBXs, it's obvious that IP PBXs are the way to go), because you really start to get operational benefits when you can interconnect multiple locations that way. The PBX industry could have gone to quasi-open standards with ISDN in the late 80s, to take advantage of the reduced development costs and simplicity, but it mostly didn't happen.

  33. Done? by Anonymous Coward · · Score: 0

    Two 'Bad Boys' of internet audio, MP3.com's Michael Robertson and Kazaa's Niklas Zenstrom, are done taking on the recording industry.

    Excuse me? They're "done?" That's some pretty startling spin you've got there.

    Let's take a look at the facts. MP3.com is basically dead. They made several attempts to build a business on models that were clearly illegal, and got smacked for it each time. Kazaa is cowering behind a nod and a wink, but everybody knows that it exists solely for the purpose of stealing copyrighted stuff. It's just a matter of time before a clever lawyer and a right-headed judge see through the haze and shut them down Napster-style.

    And you say they're "done" taking on the recording industry.

    They're not done; they're finished.

  36. VIOP services are nothing new! by shuz · · Score: 1

    Greetings all, This is my very first post on slashdot. I'll try make it informative. www.Dialpad.com has offered a VIOP service that(I believe) is still free for about two years now. I haven't used the service in a year but I remember it being really quite good, even on a 56k modem connection. As I see it these new services saw a bandwagon to jump on and so they did. Kazaa was just another bandwagon jumper and technically so was the MP3.com website although they expanded their services to give relatively unknown bands a portal for thier music.

  41. Killer VOIP app - ASTERISK by Anonymous Coward · · Score: 0

    I think the #1 VOIP application has to be "asterisk". If is a GPL'd PBX that supports most voip protocals (SIP, h323 and others) plus it supports the PSTN analog and digital (T1) lines.
    It can gateway between any of these. And again, it is GPL'd. see www.asterisk.org

    asterisk is written is such a way that one can add protocal suppot by writting a kind of "plug in" so the "kaza thing" could be supported as soon as the
    protocal is reverse engineered.

      I completely, 100% percent agree. I've been playing with asterisk for about 2 months and it completely rocks. I'm looking at setting up two small offices with it, and I can't wait. I've recently jumped into VoIP, and asterisk was one of those projects that made me stay up way to late at night simply playing.

      PBX wise, there's almost nothing you can't do. It
      really is the _killer_ VoIP app..
