New Study Finds VOIP is Getting Better 376

Proudrooster writes "Keynote Systems Inc. made 154,000 VOIP calls during the months of May and June. In total they tested six VOIP providers and seven ISPs. Their conclusion was that VOIP isn't quite as robust as the public phone network due to dropped calls, lower audio quality, and latency (audio delay), but it is still pretty good. The worst VOIP provider had an availability of 94.8% (which isn't bad) and overall the reviewers were pleasantly surprised with the VOIP test results. Vonage ranked best for "most reliable" with 99.4% uptime, AT&T CallVantage ranked best for "audio clarity"." Personally I think 94.8% is pretty awful. I don't think 99.4% is very good either. But there is no doubt that audio quality is getting better. I only maintain my land line now for my HD Tivo to dial out from.

    I disagree entirely! When someone's life may depend on a call going through (911) I would say anything below 99.99 (repeating) is unacceptable.

Our solution was to use cell phones for back-up, but I couldn't help but point out if we had regular phones we would have avoided the problem entirely.

      Personally, I receive about that many calls over the course of a day, and place about twice that many. Thankfully, I've only called 911 twice in the past 10 years, but it would be annoying as hell to accept a ~5% failure rate for telephony.

          This is why I keep one plugged in at all times, just in case. It's rarely used, but it's a tough - drop it from any reasonable height and it'll still work - phone with an actual bell. (The bell isn't a safety feature, I just thought I'd mention it because it's cool.)

          It's remarkable, in my view, how so many people do not do this. I understand the attraction of cordless phones, but these days you can have any number attached to one base station. With four or five outlets in the average home, one attached to the base station, one for your modem or DSL modem, and one other for your answerphone if you have one not integrated with your normal phone, you should have at least one more outlet available, and if you don't, a phone line splitter costs something in the region of $1.06 (yes, you can get them from the Dollar Store, where everything costs $1.06.)

          Worse still, I live in Florida. These people suffered a week without power last year, and twice in the space of a month. And how many people have unpowered corded phones? Hmmm? Take a guess.

          On a related note, a firefighter soon-to-be-relative happened to mention the whole issue with 911 and VoIP over the weekend to me. I've posted at length my concerns about VoIP and 911, so it was interesting hearing the same perspective from someone (a) who isn't a geek and (b) who actually is close enough to the wall to know how important 911 is.

    Hey rooster: can't you put that TiVo on your home network? I don't have an HD model, but my Series 2 connects via Linksys USB wireless and works great.

    Also, although not rated (and maybe that's because it's just a re-branded service from one of those that was--I don't know), my Speakeasy VOIP works pretty well. Voice quality is far superior to my old telco service, but there are indeed occasional minor dropouts or fizzle-outs. Since I also have a mobile phone, that gives me adequate redundancy in the event my service goes down, so I've been pleased overall.

    With broadband and VOIP now coming from from Speakeasy, I can't tell you how nice it is NOT to be doing any business whatsoever with my old nemesis, SBC (formerly Pac Bell here in CA). Of course, in time, I may come to view Speakeasy the same way, but not yet. Perhaps I'm in the "rebound" phase after my divorce with SBC, but there's a spring in my telecommunications once step again.

As VoIP gains ground I hope any service that expects to be provided a land line will feel the pressure on their bottom line as customers abandon them.

    That's roughly 8 minutes of the day that you won't be able to use your phone. Given that unavailability is usually related to demand, you won't be able to use your phone for 8 minutes during the hours that you'd really like to.

  • I recently switched to a VoIP provider. The cost is about 1/3 of what a land line would cost me for the same features. I understand that a large portion of the cost savings is realized because data passes over the public internet. I also realize that this means the service is unlikely to provide service that is equivalent (in terms of uptime quality) to a PSTN line. I'm extremely happy with the tradeoff. The service has been excellent so far.

  • The problem with reliability and quality with VOIP is generally not the fault of the VOIP providers.

    Rather, it's caused by the fact that the traffic goes over the public internet. This has zero Quality of Service, meaning that they have to 'join the queue' with normal data packets. Any congestion as a result of things like Bittorrent and Kazza will kill the connection.

    Really, your grandma won't be switching to VOIP. If anyone, it'll be people who already have a cell phone and want a cheap long-distance service as their land line. If they need to call 911, they'll be using their cell.

    So many people shrieking, "99.4% sucks!!" It seems almost like karma whoring. Yeah, yeah. It sucks. So don't buy it. Can we move on?

    It depends on how the outages occur, doesn't it? If it means you occasionally need to redial, that's not a big deal at all. But if it means you might be without service for a whole day every few months, then that's terrible. There's a few subscribers who have piped up here with generally positive comments. Me, I can't say from personal experience.

    But to put it in perspective, in many places outside of first-world countries, I suspect 99.4% would be better reliability than you can get with any kind of service.

  • It was a pain to set up, but mostly due to a combination of me wanting to use a firewall with NAT and the Cable provider refusing to allow another MAC address to see the internet.

    Once I got it set up, though, it's been great.

    The audio quality can drop slightly when there's a lot of traffic, but it's rare that the volume get's that high.
    I'd like to monitor the actual bandwidth calls take.

    And I've had excellent up-time.

    I don't understand the 300mS cross-US latency figure -- my informal ping'ing has an average roundtrip less than 20mS across the US. And AFAIK, the QoS requirements of VoIP require a max of 120mS to 150mS (eg, []). I don't use VoIP or Skype on a regular basis...has anyone ever experienced 300mS?

    So far having VOIP LAN line for 6 months I can say the service is 10x better than Cell phone service. And yet every day people rely on their cell phones to do things like dial 911. I think the numbers are very promising for a reletively new technology. But like any technology it requires time to mature and find its place in the world.

    For me it has been pretty simple...

    3-4 weeks a year of tech-support hell. (older urban phone systems)
    $60 a month price tag.


    1-2 dropped phone calls a month--with calls routed to my cell when it's down.

    My installer even set me up with my DSL on it's own NID, after which I plugged the voip adapter back into the wall socket. Now all my wall phone adapters work just fine.

    As to power outages, it can be hard to find the non-wireless phone in the dark. Go ahead, tell me you have a cheap ten dollar phone hooked up. Where is it if the power goes out? Of course, since all my computer equipment is plugged into UPS's, I only worry about prolonged power outages.

    Personally I think 94.8% is pretty awful. I don't think 99.4% is very good either.

    It's just fine.

    I see a lot of people whining about how your phone would be down 4 hours out of the month if you have 99.4 or whatever. My answer is: So?

    How many times do you need to make that phone call right-the-hell-now? Out of the phone calls in the past year, I'd say maybe...20. Max. The rest were more relaxed calls to friends/family that weren't time-dependent. Out of that 20, I can think of one time when I wanted to use the VoIP to call my wife's home country (Australia) and couldn't because it was down, so instead I paid Sprint a few dollars to do it through my landline. Whoop-dee-doo.

    Sure, 911 is a concern. But keep a cell phone or cheap landline around and you have that. My landline costs me $17/month. Potatoes. My VoIP [] is worth it because it has brought my costs down from over $75/month to less than $20. Couple that with neat features of running my own Asterisk server and I have a really fun, useful service.

    I guess if you're using your VoIP as your home office phone or as a telemarketing device, 99.4% would hurt. For the average home user, the small inconvenience vs. price shouldn't bother anyone that much. I pay about $35/month for my entire phone service and my wife can call home as much as she wants. What a deal.

    99% is better than my cell phone, and I find that useful enough to pay for. Not saying they can't make improvements though.

    Before anyone hits 'reply' too quickly, I am aware that he is talking about an HD DirecTivo. I am aware that the USB ports are placebos. This technique is different.

    You can get your TiVo to use your broadband connection if you're willing to hack things a bit.

    You make a special DB91/8" stereo plug and plug one end into your TiVo's "remote out" jack, which is really just an RS-232 port in disguise. You connect the other end into a serial port set for 115200 bps on a computer running a PPP daemon. Set your TiVo dialing prefix to ,#211. Your TiVo will now use PPP over the serial port to do its TiVo related calls. I can confirm that software updates can be fetched in this manner, as well as everything else.

    You still must leave the phone line connected so that the crypto card can make its own phone calls, but THOSE calls will work just fine over Vonage (the modem bank they call into is 9600 bps). The only calls that have trouble are the V.90 ones into TiVo, and those are the ones that can be diverted with this technique.

    In my case, I actually plug the serial port into a bluetooth-to-serial module, and have a virtual BT serial port on my mac doing the PPP server duties. Works perfectly and doesn't require running a cable.

    Over on Speakeasy's service (which is a contract with Level 3), my experience is that if there are heavy transfers going on, even if SE does promise quality of service, the other traffic will disrupt your conversation. Worst case I've experienced is just high latency (one second delays are FUN!), worst case you get a lot of skips and pops.

    For those of you considering dropping a land line in favor of VoIP, I have a few items you may be interested in taking note of:

    - You can take advantage of your existing home wiring by simply plugging your Vonage/etc line into any phone jack after you unplug the phone company's connection to your house in your main junction box. On newer homes and appartments, this will be a grey box you open and simply unplug the phoen cable. On older homes you may have to disconnect wires (don't forget to wrap ends seprately in electrical tape).

    - That step complete, even TIVO should have no problem enjoying VoIP.

    - What will not work are alarm systems that are wired directly to your house so a burglar cannot prevent an alarm signal by knocking a phone off the hook. For that, you may need a connector for your alarm that will allow you to not hard wire but plug in the phone line. I choose Brinks because they had such a connection that the service guy said was for VoIP installations, though mine was the first he had done and it was only avalable since Fall 2004. Anyway, you plug your Vonage line out into this line and from there it splits into the alarm and then has another line out you can jack into your home wiring so if there is a breakin, it cuts out the home wiring and goes straight to the Vonage.

    - update yout 911 info online. Because you can take your phone box with you anywhere, you have to update your 911 info if you are going to be somewhere, line on vacation, for a while.

    - Get ready for lower phone bills, less long distance, and free Vonage to Vonage and inside your area-code dialing!

    Even old-timey phone companies are in love with VoIP, and many mainstream carriers are moving (or at least looking to move) their internal phone networks to VoIP for all their customers. What this means is that even if you and your phone buddy both have plain old analog telephone service, there's a non-trivial chance that your conversation might be carried as VoIP part or most of the way.

    I've been a Callvantage user for about 4 months, and absolutely love the service. I see a lot of people on this thread commenting about how bad 99.4% is, treating that number like server uptime... that the service is unavailable .6% of the time, which adds up to hours per month.

    I believe that this study measures something different... the number of calls that were completed successfully out of all of the test calls. This is not the same as a time-based availability measurement. 99.4% means that out of 100 calls, less than one of them failed. This doesn't necessarily mean the service was down... just that the call attempt failed.

    Think about it this way... 7 failed calls in a week of testing will result in the same "availability" measurement, no matter whether they were 7 failed calls in a row, or 1 failed call a day. The former indicates a real outage, where users would likely be unable to use the service if they wanted. The latter might indicate a temporary glitch (perhaps with the TA even) that could be resolved by immediately re-attmpting the call. The former is a much bigger deal than the latter, but the numbers they've given us don't distinguish them.

    This matches my experience with Callvantage. I've never noticed that AT&T's service is "down". Sometimes when I attempt a call, it doesn't go through on the first try, but on the second try immediately after the failure, it completes. I've always chaulked this up to Internet flakiness. To repeat: I've *never* noticed an outage where I couldn't make a call, or where calls didn't ring to my cell phone (and I know... this is my business line).

    Anyway, the point is, 99.4% can mean a lot of things... and we don't really know how these call-completion numbers really match to service availability.
