Why does everyone think your computer has to be on to use VoIP?
Why does everyone think you need an IP phone for VoIP
All you need to convert to ip is an IAD (integrated access device) like the "book sized device" mentioned in the article. D-link makes one, along with many other customers.
Also, currently just about all carriers, in the US and abroad have trials or fully deployed carrier class VoIP solutions. And it is secure, and it doesn't take up more bandwidth, it actualy takes less bandwidth becuase POTS phones have gaurenteed 56k line accross the world, while with VoIP you can use codecs the support silence surpression. Within the next three years, anyone with a broadband connection will be offered VoIP beucase it is more affordable, has more features, and is easier to add new features to. The only thing that is holding most people back is the fact that most cable and dsl broadband networks don't support QOS.
Sure, when you pick up your phone you'll lose 56k of your precious bandwidth, or about 7k a second. And it is less secure, but if someone is intercepting the RTP (real time protocol) packet stream, chances are the call has been dropped. Also, the packetization rate will be between 10-20 ms, so if you lose a few packets, you won't even know, and the person interception them won't even have a clue.
Also, in Japan and Korea, cellular phones are much smaller. This is because they don't have to support the outdated analogue technology that current US wireless carriers must support.
Interesting Note: I work in a pre-sales lab and we use coppper mountain DSLAMs and SDSL IADs (intergrated access devices) to deliver VoIP via DSL in conjunction with our media gateway server, softswitch, and signalling gateway server.(Sonus VoIP and OSPA partners)
Most DSL or Braodband IADs that that allow you to connect your existing POTS (Plain old telephone system) phones to a VoIP cost about 300-500$.
We currently have 2 copper mountain DSL IADs in an ongoing demo which support up to 8 POTS phone lines a piece ie 8 people can be talking at once over one DSL line.
Of course, if the cap is at 206k/s you could only use 3-4 phones, but copper mountain does make 2-line DSL IADs that are much more affordable.
Of course VoIP is not really feasable for an ISP of this size unless you expanded your nework to support at least several hundred custumers.
I work for a next generation netwroks telecommunications firm.
Qos is implemented just about every VoIP setup we produce. VoIP is extremely difficult without QoS.
Currently there are several "Super" utility very close to deployment, and he failed to mention any of them.
VoIP with cable internet and DSL runs flawlessly, as long as QoS is implemented along the border routers. You can get your cable TV, telephone service, and high speed internet all over one line. And it will work, because the next generation of switches either will or does already implement QoS, CoS, or ToS on one layer or another. And, the emerging VoIP market knows that they MUST be compatible with other carriers in the market or they will have NO chance of remote success.
VoIP also works with DSL, but does not work with satellite (obviously 250ms latency is WAY over the 150ms standard set by the FCC for voice)
THe one wire solution IS a real solution, the only barriers being your ILECS and their lack of capital and unwillingness to provide you with a true one wire solution. This solution uses IPv4, which will last until the nextgen network requires, adn the masses will use, an address for every electronic device they own
my 2 cents

too bad wellesly girls don't put out!
Go UMASS!
i couldn't agree with you more
I think mhore is pissed off because
#1 he couldn't handle engineering
#2 his school sucked
Answer to #1: Ever hear of General Education? 40 credits of required classes in ALL areas of school
#2: if you aren't well adjusted, no college program can help you. just get a good shrink
can you imagine the incredible parties there will be at this college?
