Open Source And Net Telephony

Gark writes: "There's an interesting article at Upside Today that talks about the Bayonne project, which has the potential to change the telecommunications industry the same way that Free Software has changed computing. It's interesting that the project got its start when a proprietary software developer was going out of business, and decided to GPL their source code, thereby creating new business opportunitites." The article talks a lot about Open Source and the Net, compared to the Telco industry and its history of proprietary systems. It's a good read.

      Actually, probably the best thing to do would be to modify copyright law since software gets obsoleted so fast.

      I realize that software is a never-ending project, and that code written several years ago may still be critical to a company's well-being.

      Anyway, suppose a new law was put in place that put software into the public domain some time after it was copyrighted, I suggest 10 years. This would help a little to increase market competition, would allow for more efficient programming (it's still marginally useful) and would entice companies to innovate, otherwise their ideas they repeatedly use would just get into the hands of other companies (take MacOS 9 as an example, it's ESSENTIALLY the same as 10 years ago except for the colors textures and bugs, don't flame me, it's an example)

      Under the Universal Copyright Convention (Berne), no party may have a copyright term of less than life+50/75 years, and no party may reduce their term of copyright. There are roughly 180 nations other than the U.S. who are parties to the UCC; IIRC you need 2/3 to go along with changes before they take effect for the change-ratifying parties.

      So, before such a law could take effect (unless you wanted to make U.S. copyrights invalid across the world), you need to get 120 nations to sign off on it.

  6. the SS7 network by wishus · · Score: 5

    A brief history of the telecom network:

    In the late '70s a great change happened to the telecom systems of the world - the separation of voice and signaling networks. No longer was signaling (call setup, etc.) done over the voice trunks. Old phreaks may remember when the blue boxes stopped working. This was because of "out of band signaling".. the call setup and takedown, etc. was taken out of the voice lines. Having a separate circuit-switched network for signaling also allowed us to do things like 800 numbers, 911, etc.

    Now, the standards for Signal Points (SP) on today's SS7 network are very rigorous. The US uses ANSI while most foreign countries use ITU. Both standards are very very rigid. SPs (depending on their flavor) are allowed somewhere between 3 seconds and 3 minutes of downtime a year. That's for the system itself, not the network links, which fail more often for various reasons. The system has to be there to reroute traffic when the links go down.

    Keep in mind this is very oversimplified.

    Now, the latest revelation in telecom is the SoftSwitch - a "Software Switch" basically.. These don't run on Windows NT, or *BSD, or anything you might run on a personal computer or internet server. A successful SoftSwitch demands a fast, tight, realtime OS, that can be fitted snugly with the hardware.

    I don't think the open source model will work with telecom becasue this is not the kind of thing you work on at home in your spare time. This is not the kind of thing you can release to the community in alpha, and wait for them to lend a hand. This is not the kind of product that would benefit from having the source shipped with it. The customer doesn't have time or know-how to hack on the code and recompile if there's a problem, or the equipment to test it properly before putting it on the network.

    One respect that makes telephony unique is that most telephony solutions (such as small office PBX's, voice mail systems, IVR's, etc) are primarly delivered thru a VAR channel, and there are some 5000 indipendent telephony dealers in this country alone. These dealerships are often forced to supply customers proprietary products that they are only allowed to modify in the expressed manner that has been permitted by the manufacturer. While each mfg talks about "forming partnerships" with their reseller channel, manufacturers use various means to keep control of the reseller and the end user (such as requiring "exclusivity" to carry brand X product, disclaiming of warrenties, etc) and, in that they are actually quite removed from what the end user actually wants and desires, they often produce less than "clueful" products.

    What the GPL would mean for this market is that the reseller would be free to adjust a given solution to meet real and actual customer needs, and that the means to do so can not be taken away from the reseller later on. In this sense, it means one has to form a "real" partnership with the reseller channel rather than marketing sound-bites.

    The telephony reseller channel is one where solutions are fit to customer needs and the majority of the profit often comes from service agreements and support, rather than the sale of tangible goods.

It's only a manner of time before it all migrates to an IP based network, and even AT&T has acknowledged this by declining from buying anything other than IP based equipment - this is why Nortel, Lucent, Ericcson and the major provides of old-school equipment are forging into new markets.

    Using the net for voice/media calls is still problematic because QoS and billing issues have yet to be sorted out. The mistake that many people make is to think that there will be an "internet telephone company" - there will not be, because the whole concept of "a telephone company" is defunct in light of the Internet. What there is, is a collection of bandwidth providers, and on top of that, there are all sorts of services, of which telephone is one.

    What will happen is that internet QoS mechanisms will come into place, and you will be able to "buy" guaranteed information streams across the network, and on top of that, you can run your video/audio/multimedia one-to-one or group communications tool. That obviously assumes the availability of considerable bandwidth, and it will take a while before the networks are in place, but you can be sure that they are heading there.

    While a lot of other software has become popularised through open source, no integrated telephony software has - I accept that there are various bits of software (desktop phone, internet videophones, etc), but there is no real movement or interest group in the way that there is for other software technologies and no real common understanding of what it means to make voice calls across the Internet - not enough people understand this concept yet. Even systems like IRC had a large interest community of developors that evolved the code. Where has that been happening for telephony ?

    This is summary: the concept of a telephone company is dead, and so is the idea of SS7 and 'old school' switching technologies. The internet is rapidly replacing all of this as a common transport medium upon which voice calls will be just "one type of service". Although various internet telephone companies are around, there is no real unification or movement to develop an internet based phone/media software platform that is open, extensable and integrated on the desktop for the use of the masses. And the masses do not yet understand the concept, nor have an incentive make the change - there needs to be some kind of infrastructure in place (i.e. once many people start to use DSL services, then perhaps if voice/video phone services became available, people would make the voice/video call over DSL/internet rather than making a standard POTS call, and from then onwards, would just not go back to making POTS calls ever again).

    Too many people still think that the internet is something at the end of their phone line, that do not yet realise that their phone line is the internet, and a voice call is just some service offered.

    The sorts of concept video phones that have been thrown around are also in the wrong paradigm, they work on the idea of an 'enhanced telephone' - the whole idea of a telephone is dead, as is an enhanced one. What is alive, and always will be, is the idea of 'communication' - "call mom" is something people want to do irrespective of whether they use a phone or an internet multimedia service -- all the more better by using the latter and being able to see her face as well.

    Through all of this, the biggest problem is the paradigm shift - people still thinking in old ways until a sort of critical mass and juncture hits them in the face, and then they see the new world, and by then, the old world is long on the way out.
