      Will that work thru nat? (Behind my firewall)

      Yes, but there are some possible quality problems.

      Note that I'm speaking from my Vonage experience, but I expect Lingo would be the same.

      Yes, it will work from behind a NATing router/firewall. Assuming you've got a good stateful firewall you shouldn't even have to mess around with any port forwarding. In my case my firewall is a Linux box w/iptables. Works great. If you have a less intelligent firewall, you may have to forward some UDP ports to your VOIP box.

      However, if you can, you're better off putting the VOIP box in front of your firewall, so it can prioritize the voice traffic over anything else. Otherwise, a large upload or download can cause voice packets to be lost, which results in a kind of a stuttery sound. In severe cases it could mean a completely lost connection, although I've never seen that.

      If you put the VOIP box in front of the firewall, it will provide DHCP and NAT service for whatever's behind it, and I think mine (Motorola VT1005V) can also be configured to do port forwarding. So I could connect the VOIP box to my cable modem and then use port forwarding to make my HTTP/SMTP/SSH/etc. servers accessible.

      Because Linux can do QoS, I put my VOIP box behind the firewall. Actually, I haven't yet gotten around to setting the QoS configuration to favor VOIP traffic, because it hasn't been necessary. I've been using fair queuing for a while to ensure that every connection is guaranteed to get fair share of the bandwidth, and that seems to do an adequate job of ensuring the VOIP connections never get starved. I think in order to starve the VOIP I'd have to get enough high-traffic streams going that the VOIP connection's "fair share" is less than the 90kbps it requires. If I ever have problems I'll just tweak the traffic shaping to prioritize the VOIP traffic over everything else.

Having moved recently from a city in Canada to the USA, I knew my wife and kids would be calling home often, ramping up my phone bills. So, I ordered up my Cable modem, ordered my Vonage and 3 days later opened the box that FedEx dropped off at my place and installed the VOIP router. As it is, you can plug a phone right into the VOIP router's phone jack and start talking but this limits you to the single phone (unless you get the cordless phones with multiple phones and one main base station. What I did was I disconnected the Telco from my local phone loop (the loop of phones in your house that all connect to the telco's line at a box in your basement). I then plugged the VOIP phoen connector into the wall phone jack. Since all phone jacks are on the same circuit, I was able to get dialtone from anywhere in the house. So, my family can use the phones plugged in to any phone jack in the house. (*** It is important that you disconnect the Telco from your phone lines as it could damage the VOIP router).
      One additional feature I ordered with my Vonage is a Virtual phone number. I ordered a phone number which is local to Toronto, Ontario (where I lived) which rings on my phone in the USA. All of my friends and relatives can now call that as a local number and pay no long distance (I can get up to about 4 or 5 virtual numbers in North America). I can call anywhere in the USA and Canada with no long distance. So, I pay $29.95 + about $1.50 tax each month and that's all..

      The other great thing with VOIP is that I can take my router with me on vacation. As long as there's high-speed interent where I am (many hotels offer this), I can plug it in and receive calls made to my home number(s) and place calls as if I were calling from home..

      So yes, VOIP really IS that interesting! I get every feature imaginable (voicemail, caller ID, 3 way calling, call forwarding, etc.) without paying a single penny extra. Wires?

This means that for the 4 hops, you get approx 1/2 second delay which is annoying as all get out, but is a fact of any geosynchronous satellite communication.

      It's not that it's a "flash in the pan" as you put it. It's a step in the right direction. Voip providers (or at least the one I engineer for) aren't concerned with PSTN other than for now it's a nessesary evil and temporary source of very modest revenue. No what you say is true but what you miss is that a Voip provider brings a much bigger piece to the puzzle. How many other companies can make this work? VERY FEW, and the reason behind that is that they can't find the right mix of technology, and business. Voip isn't a poor mans game, nor is it the "free ride" everyone paints it to be. When you go VoIP you pay for someone to implement or manage it or both. Your also buying into a theoretical long term investment. The advantage to voip is that it puts you into a framework that can grow to new heights faster and better than the PSTN because of it's nature.

      Now on to the one other noteworthy post I wanted to add to.

      "What will further delay VoIP from entirely killing the PSTN, smong other things, are (1) The vendors (bad vendors!) are doing a Microsoft-like embrace-and-extend of SIP (the session initiation protocol used to set up a VoIP call) (2) Meeting regulations like CALEA (the law enforcement act that gives the government the power to tap the phones) (3) Truly connecting Voice Over IP "islands"... because how to you share IP addresses of phones and maintain privacy (like suppressing caller ID)... and the best savings come when you can remove the PSTN (public switched telephone network) entirely."

      First off how are the vendors bastardizing sip by embracing and extending a standard that encourages and has built into it (at least for the most part) a systematic way to replace the PSTN and keep phones predominately the same? Also I challenge you to tell me of a better standard. What VoIP needs is a standard to indeed rid us of the islands you mention.

      Secondly how does CALEA slow down VoIP? A provider of VoIP has a much easier time providing for "tapping" than a traditional LEC does in many ways. Cisco's Span Sessions for instance, need I say more?

      Thirdly, you talk about connecting these islands, yet you talk down to adoption of Sip? And how does sharing IP's come into the picture? How do you share and IP unless of course you mean via NAT. And even if that is the case then you haven't looked into how SIP works have you? Sip is in basic terms simply a proxy device and a setup protocol similar to how DNS doesn't carry the data, it's a pointer to it and a middle man to the conversation as a control element. Sip has control of the caller id, you can at that point much more easily "mask" caller id with NAT because at that point the last true remaining indicator of who you really are is your IP address, not your caller ID.

      Now do I want everyone to think that i am trying to shoot down or flame someone? not at all. But we can all think this through for ourselves.

      Being the Senior Engineer for a Managed VoIP Solution provider offers me a unique glimpse into the future of this and as such I think you shall all be shocked. More so than you might think with the suprise waiting around the bend for the backbone providers to unleash. Beware, they are no where near done with the bumps in the road yet.

DSL will work with VOIP, but so will typically a cable modem, or a WiFi connection to a high-speed backbone. In the first case, you need a phone line to get DSL to begin with. Most of the bandwidth on a DSL line is dedicated to data transfer, the amount of bandwidth dedicated to sending the voice data is only a small percentage, but brings in the lion's share of the revenue. In the second case, you can use your cable modem to run VOIP. No telco landline required, and you still get to have all the goodies of VOIP.

Up to 200ms or so is still a doable conversation, over that and you're starting to get a situation where conversation breaks down.

    Note the 70ms comes from the time it takes for voice to travel across a reasonably large room - a delay the human brain will automatically account for without interpreting it as having a lag in the conversation.

      Latency is the problem - getting down to the ideal of about 70ms regardless of where in the world you are going is key.

      You aren't going to be able to reach the 70ms latency from any where in the world to anywhere in the world.

      The speed of light is about 299,792km/s. The cicumference of the earth is about 40,000 km, so the time it takes light to go half way around the world is about 65ms.

      Electrons in a wire and photons in fiber don't travel as fast as light in a vacuum and wires/fiber aren't layed in a straight line anyway. Add in encoding/decoding times, and delays caused by going through routers, and you are going to be lucky to reach 100ms.

    VoIP was technically possible in 1995 or so. Just like streaming a movie over a high speed Internet connection is theoretically possible today. It just takes time to commercialize. The reason it is getting so much attention now is that: (1) The networking industry is solving the latency problems that plagued voice (2) Advanced audio codecs are providing high quality voice in much smaller packets, improving service levels (3) data traffic dwarfs voice traffic, so it's possible to put the voice onto the network as "high quality traffic" and get the required throughput and completely avoiding the entire telephone network support and infrastructure cost (4) It's cheap as all get out in comparison to PSTN service.

    What will further delay VoIP from entirely killing the PSTN, smong other things, are (1) The vendors (bad vendors!) are doing a Microsoft-like embrace-and-extend of SIP (the session initiation protocol used to set up a VoIP call) (2) Meeting regulations like CALEA (the law enforcement act that gives the government the power to tap the phones) (3) Truly connecting Voice Over IP "islands"... because how to you share IP addresses of phones and maintain privacy (like suppressing caller ID)... and the best savings come when you can remove the PSTN (public switched telephone network) entirely.

    Many real companies, governments and other organizations are looking into and deploying Voice over IP. It IS happening.

    As far as disappearing to be replaced by something else, that's a problem too. An analysis of FCC and industry data will show you the lifetime on such telecom equipment is VERY long - in many cases longer than a decade. So it will last, if for no other reason than "something else" isn't that much better, so it doesn't cost justify.

    The real key here is that POTS is in trouble. The number of lines is going down (due to wireless) and the corporations are in a rush to Voice over IP. Why? Becuase it's cheaper, and the amount of voice traffic is now dwarfed by the data traffic. Thus, you can carry the voice traffic on the data network and completely eliminate the voice network. You can even do it with high quality of service for the voice, and it works because it's such a small percentage of the total network traffic. Expect some big announcements over the next year.

      You don't need a provider to do deploy VOIP. The only essential thing that a provider is giving you is an interface into the POTS network. Once everyone is on the internet, you'll just be able to "phone greg@home.com" and a currently non-existent protocol will resolve that to whatever communication Greg has on hand, by talking only with Greg's own equipment, not that of any provider. The internet is Peer 2 Peer.


      Sure, you will still be doing Voice over IP, but it won't be any kind of huge revenue generator for VOIP companies, and, as commercial entities, they will shrivel and die. But I wouldn't worry, they probably have a good ten to twenty years of good times before people figure that out.

      You have more faith than I do. Once we have a way to link the "islands" of Voice over IP that corporations and individuals are creating, I would expect Voice over IP to turn into a product, (think fax machine) rather than a service. Buy a Linksys device from your local electronics store and plug in. There will be NO revenue involved except for the "bit carrier", and that will be a race to the bottom between cable carriers and DSL providers. I would say that happens sooner rather than later. I think 10 years is generous.

      Good thinking.

      The protocol you envision has been around for a couple of years now, and it's called Session Initiation Protocol - SIP. It uses a URI like to find the party you are calling, and after it has served it's rendezvous function, the media is sent peer-to-peer via RTP.

      There are also plenty of soft- and hardphones using SIP coming out, some even with video.

      So, yes, if everyone were using SIP and the internet, the Telco's would go the way of the Dodo bird with their current business model.

      Unfortunately, a lot of what is called VoIP these days uses SIP, but just to emulate the PSTN, often refered to as PoIP, PSTN over IP.

      As long as SIP [terminals|clients|user agents|phones] don't allow URI dialing, the telcos will have it their way, and the VoIP industry will profit just like the telcos, using a business model based on artificial scarcity. So make sure whatever SIP phone you buy supports URI dialing.

    Big business is already investing in VoIP. They are deploying it internally and having great success and savings.

    Small business will be delayed - for the reasons you mention. However, in another post I mention that I think you will see AT&T and some of the existing IXCs (inter exchange carriers, aka long distance carriers) enter into the VoIP market in a big way. Expect them to use that as a lever to displace the local carriers if they can. It will come, but it won't be the little guys who bring it to the business world.
