PC Magazine's In-Depth VoIP Review 153
Voipster writes "PC Magazine has completed their in-depth review of six VoIP providers. The Editor's Choice award goes to AT&T's CallVantage service.
Unlike other reviews that consist of making a few phone calls, PC Magazine uses Minacom's PowerProbe 6000 VoIP testing equipment which provides hard numerical scores for a DTMF detection test, a fax transmission test, and two voice quality tests, PESQ (Perceptual Evaluation of Speech Quality) and VQES (Voice Quality Evaluation System).
However, after a very detailed analysis of each provider, the calculated scores don't carry much weight as they award AT&T's CallVantage the Editor's Choice and four other services strangely tie for second place."
Lots of VOIP phones in 1 house (Score:5, Informative)
I don't know why they always say crap like this. All you have to do is go outside your house the to telephone box, disconnect your phone line from the local network (it's a good idea to leave a note saying that it should remain disconnected and tape the leads, just so it doesn't get reconnected...)
Once you've disonnected your house from the POTS, you can plug your analog telephone adapter into ANY telephone wall outlet in the house! This makes all of your phone jacks live with telephone service from your VOIP connection.
That is, unless of course you have DSL. In that case you should either use a 2-line adapter to run your VOIP phones on line 2, or change your DSL connection to line 2 and plug in your ATA normally.

VOIP quality must be measured over time. How is the performance at 8PM EST on Saturday? How many drop outs on a 1 hour call?
This gets more complicated as ISPs compete for service. I know of someone at Cox who was intentionally messing with VOIP provider traffic (and laughing about it).
I switched to Packet8 in September after using Voice Pulse for 5 months. Voice Pulse call quality had become embarassing, even after trying their higher compression codecs. "Mom, can you hear me??"
Packet8 quality has been excellent (much cheaper too). All this on Comcast. I can even run P2P at 10KB/sec upstream with P8. VP was problematic with no P2P.
A friend who lives 50 miles away has tried Vonage, Voice Pulse and Packet8. They all pretty much suck for him. He is on Comcast but it is former TCI infrastructure.
He agrees that the best VOIP he has ever had were when we use Creative Labs VOIP Blaster between Seattle and Virgina for over a year.
Voice Pulse tech support was useless when it came to outages (yes, they had lengthy outages) or performance problems.
My rule of thumb for VOIP is to be prepared to drop them if performance is bad. Don't waste your time. Don't get caught in a contract or a situation that will be expensive to get out of.
And don't become attached to the phone number. VOIP is a commodity, treat it as a commodity.
Vonage the new NYNEX? (Score:3, Informative)
Even their service that rings my PCS mobile while also ringing my Vonage "landline" has started flaking out. And the standard voicemail problems (mostly delayed/dropped/phantom message notifications) continue, though mostly in theory with no calls. Vonage was a great test of the VoIP concept. It's about time to switch to a system that offers something at least approaching the basic reliability of the old NYNEX residential circuit, even if I run the server myself over my redundant cable/DSL connections to my home. If there were a company reinvesting its revenue in IAX datacenters for uptime, I'd jump into my own Asterix server right now, and phase out Vonage. Maybe this review's results will withstand "corroboration testing" research on the Net, but I'd rather get a system that I can fix myself, or hire a contractor to work on. At least it beats slamming the phone down on the table.
Vonage vs. AT&T - from an end-user perspective (Score:4, Informative)
So, we debated for 1-2 weeks after we moved and finally got Vonage. Forthwith -- the pros/cons from a new user:
VONAGE PROS:
- easy setup (took 10 minutes to install Motorola VT1005)
- call quality is good so far (using QoS on a Linksys WTR54G router w/ voice terminal BEHIND router)
- no trouble dialing most local and long distance #'s
- straightforward billing
- very clean web interface
- nice basic features
VONAGE CONS:
- voice mail is choppy/hard to hear over the phone
- hard to find the better-reviewed Motorola VT1005 (Radio Shack tried to make me ACTIVATE IN STORE???)
- instructions for using services are in FAQ format mixed with a lot of technical installation stuff
- basic features are limited compared to AT&T
Now, I got Vonage, and then the next day after telling my boss about it, he got AT&T Callvantage for his home business line. He let me call in and access his web-based interface.
AT&T PROS:
- SUPERB feature set -- many more features than Vonage
- web-based interface integrated with phone (click-to-dial -- no outside apps required)
- call quality is good from boss' overloaded DSL connection (some servers behind his router)
- faxing is officially supported, from what I could tell (have to jerry rig it sometimes with Vonage)
- voicemail interface is really powerful
- automatic phone book setup based on incoming calls that become part of account (click on # to add it after you ID the caller)
- WebEx-ish conference call scheduling/notification feature
AT&T CONS:
- web-based interface is buggy (Javascript errors w/ FireFox -- no problems with MSIE)
- cost is higher
- really cool features aren't included standard -- expect lots of side charges
So far, my boss likes AT&T for his business line. He's thinking about getting all of us AT&T voice terminals for our small business. The conference calling costs $.35/minute for 10 people, which isn't really bad, I guess, considering that you're doing it from your own network + an outside call-in line from AT&T.
Vonage seems, to me, to be good for the home. It's simple and works, but I've read many a report of bad customer service and other weird issues. If you don't have to have the features for a business, then it's probably a better deal, but AT&T CV is close with only a $5/month difference for a more fully featured unlimited calling plan.
I did my research on Vonage at http://www.broadbandreports.com/forum/voip [broadbandreports.com] before buying in. The regulars in the forum are very helpful and have a lot of diverse consumer-grade VoIP experience. For example, I learned that, in my new house, I can unwire my outline phone connection at the box and then plug in the Motorola VT1005 into a jack inside the house to power my phones. Going to try that in the next 2-3 days, I think, barring weather issues.

I didn't want to turn my note into a Voice Pulse slam-fest, but that was another reason I left.
Voice Pulse didn't lower their prices with the market. My VP unlimited remained at $38/month when Vonage went to $30/mo. Then Vonage went to $25 and VP stayed the same.. They don't seem to understand the low barrier to switching carriers. I pay $20/month for unlimited packet8 and my international rates are cheaper too.

In addition, the cable company's version of VOIP installs even heavier duty UPS boxes when you order through them. 911 also works as expected - I know this because my young daughter sometimes dials "911" instead of the "991" prefix, which is common in this area.
Re:No Skype? Here's my review (Score:3, Informative)
Can you recommend any free service that has better software//available hardware?
Well, I'm still researching the options, but I can give you a few pointers. First of all I have to point out that interoperability is one of the major issues for me, I use mostly FreeBSD and Linux and I want to be able to use the software to talk to my Microsoft-infected friends as well. The options so far seem to be:
OhPhone: free to use, open source, based on OpenH323, which means it works with other H323 software (well, at least in theory). I've used it on FreeBSD to talk to a friend who used Microsoft NetMeeting and the sound quality was absolutely horrible regardless of the codecs used, I could not even understand what my friend was trying to say. I would highly advise you to stay away from this product.
KPhone: free to use, open source, based on SIP, which should make it possible to use with friends who use MSN messenger (I know!) through a SIP service like sipgate.de or similar. I have yet to test this...
On a sidenote, I find the review by PC Magazine to be really superficial, they did not even bother to do proper research, let alone test the available software thoroughly. Just take a look at this paragraph from the page on Skype:
Skype is the clear category winner for its wide array of communication options, lower per-minute pricing than Dialpad, and a clean, usable interface that worked consistently.
Clean interface? Anyone who's used it for more than 30 minutes knows that the GUI gets messed up to the point where you don't know if you're still on the line and sometimes you cannot even click any buttons, you have to just kill the client and restart it.
The service works with both Windows and Mac OS systems, and you can voice-conference with up to five people or conduct multiparty chat sessions.
Why is Linux not mentioned? And why do they not even mention the fact that Skype provides AES encrypted communication that employs 1024 bit RSA to negotiate symmetric AES keys? Even an average user would be able to write a more detailed review than this, this is pathetic.

There are other ways to do this with DSL without doing the two line thing, which may not be an option for apartment dwellers (like me) who only have one pair available.
The first step is to identify which phone jack is the first one on the loop coming off of the phone box outside. Now take apart the jack and disconnect the pair coming in from the phone box, that is the pair that carries your DSL signal. Now wire this pair into a surface mount keystone jack or whatever and plug your DSL modem in. Put your original jack back together and back in the wall, you have now isolated your internal phone network from the phone box and wire up all of the extensions to your ATA. See pictures of the work in progrees here [acerbic.org]and the finished outlets here [acerbic.org]. For good measure I also diconnected the the last jack in the series so I'm not sending dial tone to the neighbors place
On a side note I've also managed to get my rotary phones working with Vonage by ordering a Pulse to DTMF adapter from Mike Sandman [sandman.com] who also has lots of other neat telco goodies at his site. The Linksys router sends enough voltage to ring my Western Electric 302G and my 554 wall phone clearly, though the 554 wimps out after a fe rings. I think this is because my 302 was originally setup for a long party line install and has a ring isolater tube installed to compensate for weak ringing voltage from too many phones on the same line. I'm looking to replace the 554 with a 364 wall phone from a party line install, with the hope that it'll play nicer with the Linksys.
In any case it's immensely satisfying to use a 60 year old phone on a VOIP service...

Next time your cable modem is down call Comcast. Get them to send a truck out. Explain that the cable modem keeps failing.
I did this and I have not had a single droppped connection since the tech came and re-routed the wires. And, yes, it is Comcast! The problem was that the initial installer had put too tight a curve in one of the wires.
Not very 'In-Depth' (Score:2, Informative)
CallVantage's conference calling is NOT free, it is 0.35/min.
CallVantage DOES have a comprehensive call log, including incoming, outgoing (missed calls show as incoming). The call log is not searchable but it is sortable and you can dial a number from the webpage, one of my favorite features.
CallVantage DOES offer call forwarding and call 'hunting' to 'outside' numbers and is configurable to work with a set list of incoming callers. The author states that two other providers are the only ones that offer this feature.
CallVantage also offers a default number. If for some reason your ATA is offline, then it forwards all calls to the number you specify i.e. cell phone.
Although I have not tested it, CallVantage very clearly claims to support Fax Machines, modems and PVRs. Claims can often be over stated, but the author does not even acknowledge the claim.
The author also claims that Broadvox and Lingo are the only vendors to offer secure web interfaces which is grossly untrue. I am looking right now at https://secure.callvantage.att.com, scratching my head in wonderment...
The author does not mention the 'Do Not Disturb' feature, or the fact that call filtering is available for $2.
It's just unfortunate that people will make their decisions based on this 'In-Depth' article...
I have to say, I have been very happy with my service. No one I have called yet even knows that it is a VoIP line. I am recommending this to everyone I talk to.
