    I had a rather frustrating experience with the Net2Phone Voiceline product. Simply put, no matter how I tried to install it, it wouldn't give the green "provisioned" light or a dial tone.

    Their tech support was less than useless at telling me what was wrong... they just processed the return instead.

      Speech coding techniques used in VoIP are well tuned to human speech, for which it may still have poorer quality than ordinary phone lines in terms of signal-to-noise ratio, but sounds about the same quality to the human ear. When a modulated signal is fed into a speech coder, you get way poorer SNR than a telephone line, so the transfer rate you can achieve is generally much lower than the 33.6kbps achievable on a phone line, and definitely much less than the size of all these VoIP packets generated, so t

    Many telcos are using VoIP in parallel with their PSTN backbones, and this is ok - most users don't even notice this behind the scenes VoIP application.

    When it comes to services to end users, except for companies like Vonage and a few similar ones there's a huge gap. For example I've subscribed to Stanaphone just to find out that my account disappeared simply because I didn't use it for a month. Well, there's no way these companies can compete with operators if they keep this kind of policies in place. Could you imagine if you're enjoying a 45 days holiday in Europe (or in New Zealand, which is really cool!), and when back home find out your phone doesn't work anymore because of this kind of policy?

      There is no real reason why international dial-up calls have to be expensive and VoIP ones cheap. Once dial-up calls hit the first exchange (in most places) they turn into digital soup anyway. Having dedicated switching that is suited to dial up (isochorous etc) means you can stuff more dial up calls through a given wire than IP calls (which must carry all the extra IP crap). Extra capacity in those wires can be used to shift IP traffic.

      The days of high cost international calls are limited. Here in New Zealand I can use my Vodafone mobile to call various countries (Australia, Canada, US, UK, Ireland) at the same rate as a local call.

      So far, VoIP's main attraction has been lower cost calls. THis won't last and VoIP will have to find a better way to justify its existence.

      • There is no real reason why international dial-up calls have to be expensive and VoIP ones cheap. Once dial-up calls hit the first exchange (in most places) they turn into digital soup anyway.

        If you define "most" as medium to large-sized cities in major industrial powers, then this is correct.

        However, in reality "most" countries are relying on copper telephone systems from one end to the other. Some countries and territories don't even have real-time telephony unless an outsider brings a sat phone.

    Having used Vonage for several months I can say I am very pleased with their service and the quality of the calls. Before Vonage my only phone was a SprintPCS phone. When I got Vonage and called family/friends to tell them about a new number most of them commented how much clearer it was compared to the PCS phone I usually call them on.

    The only time I have had a 'problem' was when I was downloading some files on bittorrent AND playing FFXI Online and received a phone call. There was a slight echo audible on my end.

    I have actually convinced my father and two friends to ditch the local phone company and get VOIP. They are also very pleased with the service and money they have saved, which equals free months of phone service for me! ;)

      Supporting (generally) the parent post, Vonage is pretty good. I've been using them for my main work line for about 2 months now. Quality of service is excellent and the voice sounds quite good (think high quality cell phone) most of the time. You get a ton of great features for not too much cash. I love getting my voice mail as an .WAV file in an email, and it is really easy to foward calls wherever you need them.

      The only time I have a problem with a connection is if I'm downloading, or worse uploading (dsl) something big at the same time which is entirely expected. (only so much bandwidth after all) My only recurring problem is that the Motorola unit they gave me tends to drop my PPPoE connection about once a day. Not quite sure why and there aren't a lot of settings to tinker with. I don't have that problem very often with my Linksys WRT54G and I'm pretty sure it's not the DSL provider (SBC in this case) causing the problem.

      Anyway if you are thinking of Vonage I can readily recommend them if you can tolerate the occasional (and easily fixed) downtime. If phone availability is mission critical to you or you aren't especially technologically inclined, you might look for a more traditional alternative. But overall it's a great service, especially for home or home office use.

        If you can deal with not having a functional phone every now and then, then I'm certainly not going to argue with you, but this casual acceptance of "things break" is rather surprising. And somewhat disturbing, as it reduces the incentive to make things work well. I, at least, would vastly prefer a pencil and paper that "just work" to an electronic notepad that did OCR and networking but a habit of conking out at the most inopportune times; I've got enough stress to deal with as it is.

          There are a couple of point's I'm going to make in response to this.
          1. Vonage's VOIP technology is based on a system that is FAR more complicated and less tested than POTS. Furthermore it is an application of a general purpose technology to a specific use, whereas POTS is a purpose built technology (voice communication) which just happens to be cludged for other uses (modems/DSL). In fact my VOIP is riding on a DSL circuit sitting on top of POTS. Less reliabile is unavoidable.
          2. For $20 a month I get features that would cost me nearly $100 using POTS. (and some features I cannot get at all) Furthermore there are no long distance charges unless I call internationally. Plus I can take my Vonage system anywhere I can find an internet connection which I CANNOT do with my regular land line. While I don't deny that the reliability of POTS is something to be admired, Vonage gives me WAY more bang for my buck.
          3. As an engineer I'm not happy unless something "just works" but I also recognize how rare that really is. VOIP will probably get there someday, once it has had 80 years to develop. I'm not going to stop using a new technology just because all the bugs haven't been worked out.


          Does that clarify my statement sufficiently?

    • I have little doubt that VoIP voice quality can be made excellent (via compression). All it takes is a modest amount of bandwidth (6kByte/s?).

      I wonder how latency can be brought below 100 ms even with QoS. It's probably close to the 230 ms delay you get on phone calls routed through satellites. I find it irksome.

    • I've had Vonage for several months now, and it's saved me a lot of money. I do not recommend it (or any VoIP) for faxes, it just doesn't work very well. Otherwise, any bad outages I always have my cellphone or I email documents to a satellite office and have them fax it.
    • I've had Vonage for almost a year now, and initially I had the same QoS problem you had. Since the vonage box was inside the network (rather than on the outside, which is also an option, albeit a dumb one), and my router is a 3-NIC PC running linux, I was able to tweak the QoS easily. However, I hear that SOME of the newer home-cheapo routers (like the ones from linksys) can do traffic shaping now, so that would also be worth looking into.

    This is simply not true. Voice packets are given the highest priority across the network. If a voice packet does not make it to the destination, it is not resent. If the proper investment is made (you need newer switches and equipment) and the configuration is correct, it really does work great. I think it is ideal for an office with 30 people, especially if it is in a rural area where you may be paying a lot for a frame relay circuit or other connection.

      Yes, voice packets are given priority on the network IF your ISP has DQoS implemented and enabled. This is not assumed or standard on any networks I'm familiar with, and you'd be foolish to assume ISPs rushing out to benefit third-party VoIP companies when there's a push to roll out ISP-branded VoIP... Anyway, without DQoS, it's all best-effort. As noted above, given sufficient bandwidth, you'll hadly ever get jitter unless you saturate the pipe with up/downloads that preclude sequential voice packets.

However, I was told by one of my professors that the school just tried to implement a VoIP system, but the sound quality was terrible. In fact, they've already dropped it and gone back to the regular PBX / POTS system.
    • If you implement a system according to the specifications, it will not suck. If you try to cut corners and use cheap hardware, older infrastructure, etc., it will perform poorly. This says nothing of VoIP except that it needs decent-quality gear. It does say that your network designers are doing a poor job.

      When VoIP is deployed on a network that is properly configured with QoS and you have adequate bandwidth, voice quality is not an issue. When it is done right you can get voice, video and data all on the same circuit without any loss of quality. I manage 6500+ IP phones in locations in a half-dozen states and everything work just fine. It all comes down to making sure you have the bandwidth and QoS, which is something that would won't find on your average home cable or DSL connection.

      I had the same exact problem with VoIP, except I also didn't like the fact that 911 calls didn't go to the 911 center. However, I've figured out how to get around these problems:

      1. Keep a regular landline on your current phone number, just with $0/month (no free minutes or low rates) local + long distance plan on it.
      2. Build a box with Asterisk (the OSS PBX) on it, as well as 2 FXO cards and 1 FXS card.
      3. Connect the phone line from the VoIP ATA to the first FXO card.
      4. Connect the PSTN line to the second FXO card.
      5. Configure Asterisk to use the PSTN line for incoming calls, and the VoIP line for outgoing calls. (You'll probably want your VoIP company to forward all calls to the PSTN line, I know that Vonage does this for free.)
      6. Connect another ATA (you'll have to buy it yourself) to the FXS card.
      7. Get a double-pole-double-throw relay. This basically connects one line through when there is power, and another when there isn't. Let the line from the Asterisk server go through when there is power, and the unmodified PSTN line go through when there isn't.
      8. Configure Asterisk to only use the PSTN line for 911 calls.
      9. Connect the line from the DPDT relay to the phone lines in your house/buisniness.

      So yeah, that should cover it. If you want more info, chech the Asterisk-Users list under the topic "Vonage, PSTN, 911, and hardware question". I'm planning building a system with this setup later this year.

      • I thought that all phone lines had to be alive enough to let you call 911 (emergency) and 611 (set up new phone service)? Dial any other number and you get an immediate busy signal, or maybe a recording explaining? That's the way it was in all (I think) of the apartments I've lived in.
    • Power outages are a problem, but the consequences can be minimized. I currently use Vonage through my cable modem. I have my cable modem, router and Vonage box on a UPS. As long as I turn off my computer shortly after a power outage, the UPS can give me a few hours of phone usage, and I could get a stronger UPS and/or dedicate a UPS solely for the cable modem/router/vonage. Of course, if the outage is widespread and the cable service is also affected, then I won't have phone service. Vonage does have a

    Last week I played around with a VoIP box at my house just to see what kind of clarity it had, and, it wasn't nearly as good as my POTS line.

    However, I've had others swear by their VoIP. It seems to me that there is still just too many variables in the IP infrastructure for the experience of VoIP to be uniform. Not to mention the issues with power outages, 911 service, and the like.

    Another thing to note is that having voice mail sent to email is not a feature of VoIP per sey. We are currently implementing an email system that has this ability, given that you have the right voice mail equipment. While there are some features that VoIP does offer that can't be done with POTS and appropiate equipment, many of the features being touted as "VoIP only" features can be done with POTS.

    That said, about 5 years ago I was involved in a project to roll out VoIP in a new building (about 300 people, a call center of about 10 stations included). We used Cisco equipment and had two 24 channel trunks come in from POTS (one for local, one for long distance). Once it was up and running, the sound quality was nearly as good as POTS - we did have a slight echo once in a while, but other than that, it was great. We, of course, had complete control over the network, so doing QoS and stuff like that with voice packets was easy.

    VoIP, if done right, can be nearly as good as POTS in terms of sound quality, if not better. But given all the variables (phone, DSL/Cable router, your ISP, the POTS/Internet interface, etc), there are just too many places that can cause quality to suffer. And the problem becomes worse if you try and use a fax machine over a VoIP line, which doesn't have a high tolerance for packet delay.

    We're doing it for cost and flexibility:

    1) No telephones == more desk space

    2) No telephones == less money wasted on telephone maintenance

    3) No telephones == less money wasted on phone line maintenance (only run one network instead of two)

    4) IP == If you log in to VPN you can get calls transferred to you at home

    5) VoIP == cheap long distance

    6) Other features -- automatic call recording, easy ability to script call-ins, etc.

    7) PBX Box ---- WAAAAAY cheap ($1,500 for a build-it-yourself asterisk solution vs $10,000+ for a traditional PBX solution)

      Modems and fax machines don't deal well with the packet delays that can occur on VoIP that isn't properly QoS'ed. The problem is that end DSL/Cable users don't have control of the QoS of their VoIP packets beyond their premise equipment, and sometimes not even then. I shouldn't assume this, but I assume that all VoIP provide

    I am a Vonage customer and use it as my primary line. Not only can you get voice mails delivered to email (great when travelling), but you can, for an additional $4.99/month get a line that is local to someone that calls you a lot, so they can make toll-free (local) calls, even if you're in New York and they are in California.

    The feature I like best is that, free of charge, I have my cell phone ring anytime my home phone rings. That way, when I'm away, I still get all my home calls, and don't have to give out my cell number to everyone. This feature can be used for simultaneous ringing on any other number, or it can forward it to another number after a certain number of seconds without answer on the first line. You can turn the feature on/off and the change takes effect almost immediately.

    Most of all, all the extras that you pay for with normal phone are automatically included in the Vonage plan. I pay $25 a month for all my phone needs (that are non-cell), and that's a lot better than my old SBC/MCI pairing I used to use.

    I don't really notice bad voice quality, but I took a lot of time to set up my Vonage box *behind* my firewall, but then forwards all the ports necessary to have it manage the connection properly for voice-quality. For a more no-brainer setup, just route your connection to the Vonage box first, then to your router.
    • I agree with everything you said. One other additional feature that is useful is that, with the web interface, it is much easier to configure services such as forwarding. On my old land-line, I had to dial a * number plus my cell phone to forward calls. And I was never sure if I had did it correctly, because it was so spotty. With Vonage, I just log in and change it. And I don't have to be home to change it. I can change it from work, if I forgot to reprogram the phone.

      As for voice mail over email, I though

    It worries me that these articles concern themselves so much with matching traditional US PSTN services (like 911 and call centers) and very little with celluar phone services. It's probably because of the lack of a good packet switched cellular network in the US... Since GSM based phones are already packet switched, and can already do packet switched (IP) data via GPRS and 3G technologies, why aren't we seeing a strong push fot VoIP and cellular integration. An additional advantage is that the turnover of mobile phones is much higher than land lines, so technology adoption is much faster. Regards, -Jeremy

    Phones are easy. Pick them up, dial a number, you talk to the other person.

    Email is easy. Type a person's address, your message, hit send.

    I don't consider myself a stupid person, but whenever I've had a phone in my office, I've had absolutely no idea how to use any of the conferencing, hold, transfer, or even voicemail features. They vary from phone to phone, and have non-obvious icons. It took me a few moments to realize that the icon that showed a receiver going down didn't mean hangup, but speaker-phone.

    I agree that having this infrastructure will make new, better things possible, but a VoIP infrastructure isn't all that more disruptive than already having an IP infrastructure. Some novel applications came out of IP being pervasive, but I see VoIP as a byproduct of an earlier disruptive agent, not as the disruptive agent in itself.

    We're replacing our knackered commander system (15 years old) with a bunch of VOIP phones (Snom 190). Also we're splitting our shop into two premises; using a WiFi link (with WEP/MAC filtering/IPSec/L2LTP etc for security).

    Using VOIP on our local LAN/WAN, we can share the same PSTN line pool (about 20 lines total) between both shops. If someone dials one shop but wants to speak to someone in the other, we can transfer that call. Very useful, not to mention the other possibilities with Asterisk (caller ID, call logging, stats, voicemail, extensions, music on hold, etc).

    As for actually using a VOIP carrier for outgoing call... no, not yet.

    We're setting up with Asterisk and Digium TDM400 cards with FXO modules.

    Standard x86 servers, Linux, Asterisk, Digium and Snom phones add up to a LOT less than the integrated turnkey solution we were looking to get from Siemens.

      Spoken like a true bellhead, You are missing the point. VoIPs network is free (as in freedom) IP based, as in dirt cheap, if I pee it will land on an equipment vendor. Not stuck on a few media. Ever run SS-7 over cable-TV networks? How about a metropolitain gigabit ethernet lan? Youre going to say SONET, well gee, that only costs 10x of a gigabit ethernet... where can I get SONET termination? can I run packets on that? oh.. need to encapsulate it in IP... hmm... why?

      How much is that PBX in the window? ok, so Id like an SS-7 switching network, and I aint a phone company, oh? cant have one? have to run my own wires? hmm...

      Separating control from data only makes sense if the network is smart. Smart networks only make sense if the manager of the network is your friend. Usually, that is not the case for anyone except the phone company. The whole point of IP is to make the intermediate network a non-issue. make it stupid so that there isnt any value there, and it can be replaced by any number of technologies or providers. That is always going to be cheaper for end users, but not the phone company.
