      The guy who wrote this article is failing to appreciate some of the technology goals of plain ol' telephone service (POTS). For example, reliability of telephone switches is in the multiple-nines percent uptime. Analog lines provide streaming without packet-loss, and the entire network is self-powered. All run over plain copper wire.

      In other words, the phone network has opted for simplicity and reliability over innovation. It is no surprise then, that digital land-line service has made few inroads in ten years of widespread internet use. Sitting in front of a bulky computer praying for the software to work is simply too much overhead for most people to bear.

      While digital may become the dominante media for voice in the near future, there will remain a market for direct voice connections. Just look at the popularity of Nextel cell phones and you will see that direct connections have big market appeal.

    The Voice over IP Insurrection

    Daniel Berninger, an old friend, a seriously smart guy and VoIP guru of sorts, and more recently senior analyst, for Tier1 Research, has been a great man to bounce ideas off. He and I have chatted about many things, and each time I come away learning something new. So last week he argued, "in the battle between Bellheads and Netheads, we're all Netheads now." Could not agree more. Here is his long missive on the VoIP insurrection, the best and most definitive essay you will ever read on this technology, where it is headed and why it is important. This is the second of my guest columns series where I bring the experts who know a thing or two about their respective areas of expertise.

    What just happened?

    The $3 billion dollar budget at Bell Laboratories did not include a single project addressing the use of data networks to transport voice when VocalTec Communications released InternetPhone in February 1995. As of 2004, every project at the post-divestiture AT&T Labs and Lucent Technologies Bell Labs reflects the reality of voice over Internet Protocol. Every major incumbent carrier, and the largest cable television providers, in the United States has announced a VoIP program. And even as some upstart carriers have used VoIP to lower telephony prices dramatically, even more radical innovators threaten to lower the cost of a phone call to zero--to make it free.

    The VoIP insurrection over the last decade marks a milestone in communication history no less dramatic than the arrival of the telephone in 1876. We know data networks and packetized voice will displace the long standing pre-1995 world rooted in Alexander Graham Bell's invention. It remains uncertain whether telecom's incumbent carriers and equipment makers will continue to dominate or even survive as the information technology industry absorbs voice as a simple application of the Internet.

    The roots of the VoIP insurrection trace back to four synchronistic events in 1968. The Federal Communications Commission (FCC) ruled MCI could compete with AT&T using microwave transport on the Chicago to St. Louis route. The same year, the FCC's Carterfone decision forced AT&T to allow customers to attach non-Western Electric equipment, such as new telephones, and modems, to the telephone network. The Department of Defense's Advanced Research Project Agency issued a contract to Bolt Beranek and Newman for a precursor to the Internet. And in July 1968, Andrew Grove and Gordon Moore founded Intel. Innovation in the communication sector remained the proprietary right of AT&T for most the 20th century, but events in 1968 breached the barriers that kept the telecom and information technology industries apart. For the first two-thirds of the 20th century, AT&T had manned Berlin Wall separating telecommunications and computing, but eventually, these two enormous technology tracks would be unified.

    Two entrepreneurs barely out of their teens, Lior Haramaty and Alon Cohen, founded VocalTec Communications in 1993 based on the promise of packet voice technology they observed as members of the Israel Defense Force. Most military command and control used the highly survivable TCP/IP distributed data networks since the 1980's. The challenge of transporting voice over the networks arose as an imperative to support certain very sensitive voice commands like "drop the bomb", but the idea of commercializing packet voice did not occur to anyone until the arrival of Lior and Alon. How could slicing voice into 50 millisecond packets improve the telephone business? The tradition bound telephone industry types or "bellheads" spent their time before 1995 improving the Public Switch Telephone Network (PSTN) not replacing it.

    Advances in communication from writing and paper to the printing press, telegraph, and telephone shape human progress. Some might have viewed VoIP as an interesting toy in 1995, but no one presently doubts it will dominate the communication future. The economies of scale assoc

The government actually discouraged innovation by capping profit margins. As a regulated monopoly, the phone company was capped to a certain net profit. New business or old, same profit margin. This discouraged innovation, but encouraged stability. Not so much evil as the upside/downside to a decision that is more complex than people would like to think. I'm not sure if they are currently so capped, there's so much breakup and consolidation since the old Ma Bell days, some of the compatibility is probably gone as well.

The company I work for has 100 megabits of fiber connected between 8 locations through a company called Telco. They're paying $10,000 per month for the fiber and since the satellite offices need to call corporate a lot, VOIP on our own bandwidth saves thousands on phone bills per month.

      Cheap broadband for the residential user makes VOIP a possibility too. I ditched my landline last month and ported the number to my wife's cell phone.

      Six years ago, my local telephone bill was $22 per month with caller-id. My last POTS bill was close to $60. Really, all telcom reform has done for me is drive up my bill to outrageous amounts.

      The incumbent telephone companies all have their own VOIP service. Problem is, they think that VOIP is reason enough to switch and they offer paltry savings on VOIP as compared to POTS; if there's any savings at ALL. Verizon's VOIP service was $40 per month and I was paying close to $60 with just caller-id. Somehow they think that phone service should guarantee them a fixed amount of revenue. VOIP offers the very real chance at local telephone competition without requiring new players to build their own networks or rent from the incumbents.

      In fact, this has been the whole impediment to local phone competition. The incumbents have for years resisted renting out their networks to competitors. They've tried legislation and regulations to make it cost prohibitive and have pretty much succeeded while giving themselves a paltry profit line in interstate and intrastate access fees.

    The problem is, the ILECs (that's the technical term for the local phone company) aren't always allowed to roll out cable and WiMAX how they would like. Furthermore, if they did try to roll it out, they know very little about it, so it's not a guarantee that they'd end up losing the market anyway. Think of the online book market. Sure, the incumbent bookstores managed to have some web presence, but the real company that ended up as the online bookstore people tend to think about wasn't one of the incumbent providers.

    Or think about AOL Time Warner. Time Warner spent a bunch of money to pick up AOL and look where that's gotten them!

    The thing you need to remember is that VoIP has very little to do with where the ILECs want to go, and the article points this out. The phone company was dragged kicking-and-screaming into the Internet-DSL market mostly because they wanted to preserve their frame-relay/ISDN/Modem-line market and because the CLECs that they grudingly let into the market were using it. DSL wasn't even invented necessarily to do IP traffic, they wanted to be able to do streaming phone services with it.

    So, in the end, the phone companies are generally interested in the data-providers they compete with, not with innovation. If the phone company just provides bandwidth and no value-added services, that just means that the cable/WiMAX/etc. providers have won and they have lost.

    See, most people fall into the trap where they expect companies to act logically, as viewed by an external observer. And this is a logical fallicy, because they do act logically, but only when viewed as an insider.

    So, yes, it's very clear that the ultimate result *should* be two competing last-mile providers, representing pieces of the phone and cable companies respectively, plus wireless providers, plus companies offering layered phone, data, and video connectivity to your connection. But none of the incumbent providers with wire in the ground are interested at all in this, except to take out their competition.

Try reading this: http://biz.yahoo.com/prnews/040920/sfm107_1.html Here is some of it: ADVERTISEMENT According to Dr. Alan Lefkowitz, a subscriber to the Packet8 VoIP phone service, while traditional phone systems in the hard hit region were disabled from the storm, his broadband internet phone service not only kept on working but experienced no degradation in quality or consistency through even the worst phases of Hurricane Frances.

    Or rather BT have finally caught up.

    For domestic customers, BT Together offers free *national* calls for £16.50 (~$29.50) per month (off peak) or £25.50 (~$45.80) per month (any time of day).

    I dunno how this compares to the US for pricing (I suspect you're going to tell me we're being ripped off :-) but it's a step in the right direction.

    Of course, you're always free to stick with metered calls and cable operators will usually let you call their own phone networks for free (not that I'd ever, ever again let Telewest near my house)

    It's been out since about '95 or '96, is totally free and can work over TCP/IP or direct dial. And it encrypts your communications.

    Ok, I rescind my previous post. Skype rocks. It works on my wife's Powerbook, my compatibility-crutch Win2k box, and my Gentoo Linux box.

    Maybe they make enough on the $0.02/min SkypeOut service to keep them from using my bandwidth and CPU cycles for illicit purposes. :)

  31. 911 was designed for landlines by billstewart · · Score: 2, Insightful
    First of all, your cell phone will work just fine even if your power is out. If the VOIP companies were clueful, they'd have somebody build them a VOIP router with a cell-phone circuit built in so you can make emergency calls.

    Of course VOIP and 911 don't get along - 911 was designed to work in a landline environment, with communications architectures tightly tied to Class 5 telco switches and database architectures designed for phones that stay in one place, and the 911 folks haven't been willing to adapt their systems to accept VOIP connections even though it wouldn't be that hard. VOIP, like wireless, presents some new technical challenges because the equipment is portable, and if you bring your VOIP box on a business trip with you and have to call the fire department, you want firetrucks showing up where you are, not back at your house. But there are ways to design around it, whether you do something with GPS or adapt your DHCP servers to pass you geographical info or whether you have the VOIP box/software/etc. let you tell it your address.

    Complaints about VOIP and 911 are usually a cover for real complaints about VOIP and wiretapping. The folks who like wiretapping are annoyed that changing technology makes their tools obsolete, and want to force the technology to adapt to them, rather than the other way around, and they tend to use 911 as a lever to do that. After all, you want an ambulance to be able to find you if you're hurt, but you probably don't want the police to be able to locate you within 10 meters and follow you all day, so that's not the motivation they advertise for mandating that new cell systems provide user location. Similarly, the wiretappers _really_ don't like peer-to-peer flexible technology, and they're used to having hooks into traditional telcos to control them.
