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.

There is another problem with using VOIP. When the internet goes down your VOIP phone may go with it. We use VOIP phones at work and I recall a situation last year where a hacker brought our internet connection to its knees (hence no VOIP phones) and everyone was running around like a chicken with their head cut off trying to figure out how to make calls. 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.

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.

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.
