One thing I wish for in my quest for perfect Internet phone service the ability is to fix voice quality problems on the fly or at least be able to understand “is it me or the network?”

When I had Vonage service, I usually started the converation with “So how do I sound, can you hear me?” Many times there was such a delay that practical converation was impossible. If I was at my computer, I’d try quitting applications to see if that helped (usually not). After hanging up in frustration, I’d try messing with the dreaded ”Bandwidth Saver” feature. But in my opinion, AFTER the call is way too late.

Is it possible to build intelligent applications that KNOW when they’re not performing optimally and can tell you what the problem is, or better yet advise how to fix it?

No sooner had I written this when Peter Csathy, CEO of SightSpeed, let me in on a little secret (okay well it’s not actually a secret…), SightSpeed detects when your video or voice call isn’t going so well and automatically makes adjustments to improve the quality.

For example, a video call that appears jumpy or out of sync with the audio could be caused by network congestion. SightSpeed can downsize the bandwidth usage for video so that at least the voice aspect of the call is preserved or improved. SightSpeed lets you know it’s doing this by popping up a dialog box that says it’s making these adjustments. I don’t know if you can you make adjustments yourself DURING a video call, but you can easily see your upload and download speeds while talking to someone.

To see SightSpeed statistics: 

With your mouse hovering over the SightSpeed title bar,  press CTRL + S (or right mouse-click followed by CTRL + S). A statistics dialog box appears showing your current, peak and average bandwidth usage.

Gizmo Project has a Call Quality Assistant (click the bar graph in the bottom left of the Gizmo Window) that gives you an idea of your network conditions. While it shows you at a glance the quality of your connection, it doesn’t say what you should do about it and at this point in my life, that’s what I need.

 

TheVOIPGirl.com’s had another nice welcome from PhoneBoy (no, we’re not related), a prolific VOIP, telecom and technology blogger with an affable writing style. He explains things…

Check out his review of GotVoice and you’ll see what I mean. GotVoice is an interesting service that takes voicemail messages from different voicemail services (including VOIP ones) and sends them to your email inbox. You get convenient access to all your voice messages in one place. He also points out a few shortcomings of TheVoipGirl.com that I hasten to address. Thanks PhoneBoy!

Well, after eight uneventful months, Vonage and I are parting ways.  Perhaps not the most auspicious way to start off a blog about VoIP but I’m being honest here. I’m not going to go into a big rant. Flame throwing just isn’t my style. I don’t hate Vonage. The service just wasn’t financially making sense for me. The phone usage in my business isn’t enough to warrant a fixed monthly plan, even one as low as $24.99. Plus in my area the call quality wasn’t pristine. And some people do get excellent voice over Vonage. But I generally experienced crackling and lag on most calls.

If anyone has comments on Vonage quality in their area, let me know.

From the Vonage forums, it’s clear that call quality varies tremendously from region to region. My advice is that if the VOIP service, Vonage, SunRocket or whatever, isn’t what you expect, try something else. The VOIP marketplace is growing by leaps and bounds, and as a consumer you should shop around.

But now that I’ve done Vonage, it’s time to move on over to other VOIP solutions. Skype, SightSpeed, and Gizmo are the free ones on my radar and make the most sense for me given my business.

Hi and welcome to my blog about VOIP, voice over IP, Internet phone, broadband telephone, or whatever you feel inclined to call it. This is NOT a blog about women, or even necessarily about women who use VOIP services–I mean how boring is that. I called it The VOIP Girl because well I’m a gal. And I want to write about this voice over ip. That’s about it. What really prompted me to get going however, is the fact that there are few women commentators on this subject. I’m curious to see if my perspective will be any different.

I want to write about how consumers (that’s you and me) are doing using VOIP.  I don’t necessarily care about IPOs, who’s buying who, and all that insider industry stuff. There are tons of blogs out there talking about all that. In fact I would say that is mostly what you’ll find when you look for VOIP commentary in the blogosphere. It’s great stuff, but really I’m interested in how ordinary folks are using Vonage, Skype, Gizmo, etc., and how is the free stuff stacking up against heavy hitter paid services.

Thanks for stopping by.

Iristel is the first to bring HD VOIP to Canada.

Whoa…I don’t think I can handle this. We just recently enduring a long and arduous process of researching and purchasing our first “big” screen TV with…heaven help me…HD-high definition. You see in Canada it’s important to actually see the puck when the Canucks are playing. Apparently this is impossible on a 21″ tube TV with a pink stripe across the top of the screen. (Who knew?)

Maybe fellow bloggers can help me out here, but is HD VOIP something that consumers should consider when choosing a VOIP service, or is it more marketing lingo to work through? As I understand it, HD, high definition, or wideband VOIP refers to voice sampling at 16 kHz rather than at the measley 8 kHz supported by the PSTN and just about everyone else. If you capture voice with a wider spectrum of frequencies, the quality is better. They say it’s like comparing the quality of AM and FM radio. (See this article from voip-info.org).

Sounds good to me, but the catch is you have to have HD end to end in a VOIP call. It’s no good having 16 kHz at one end and 8 kHz at the other. In fact, 16 kHz downsampled to 8 kHz (which happens if you are calling a landline) may sound worse than 8 kHz from start to finish.

So I guess you can make the argument that HD or wideband VOIP is wasted on the masses when most calls travel partially over the PSTN or use VOIP networks using an 8 kHz voice capture process.

Laptop magazine has a review of Fring, Talkster, Nimbuzz and Barablu. These four apps turn your good old cell phone into an internet phone and more. Of the four, Nimbuzz is new to me and Barablu I haven’t tried yet. Fring and Talkster I’ve used and quite like, although I think having a great handset makes all the difference. I wouldn’t bother with any of these if I didn’t have the Nokia N80i to test with.

The review does a good job of capturing the typical setup process for all applications, and gives both the pros and cons of usability, call quality and the like. Author Joanna Stern points out that “regardless of which mobile VoIP service you use, you’re going to need an unlimited data plan, which costs anywhere from $5.99 per month (T-Mobile) to $24.99 (Cingular)”.

Edited May 17, 2007:

James Wanless of Talkster clarified for me that their service in fact does not require a data plan:

Thanks James

You may have heard this before: Voice Over IP (VOIP) needs a certain amount of bandwidth to be usable. In other words, VOIP needs bandwidth so that voice conversations are intelligible by both parties. Your broadband Internet connection (provided through a cable or DSL service) provides that bandwidth.

Basically, bandwidth is the amount of digital data that can be transmitted in a certain time period. Internet connections are usually measured in KiloBits Per Second (kbps). Your connection may be rated at 512/128 kbps. This means that the upload stream (leaving your computer) has a maximum bandwidth of 128 kbps and download stream (coming to your computer) has a maximum bandwidth of 512 kbps. Find out the speed of your broadband connection…

For example, a web page that is 3000 bytes can theoretically viewed in 0.05 seconds – almost instantaneously - at a download speed of 512 kbps. However, in the real world web pages don’t usually load that fast.  That’s because data is held up, or delayed by various factors. Latency is the delay caused by the physical limitations of each piece of hardware the data is passed through. Delays are also caused by pathway congestion, error checking, transmission negotiations and extra data sent with the web page to identify its type, origin and destination.

What this means for VOIP is that enough bandwidth must be supplied to allow for the transmission of the actual voice data in real time as well as extra bandwidth for the overhead required for any data transmission.

So how much bandwidth does voice data use up? Well that depends on the codec (enCOder/DECoder) used to compress the data. Anywhere from 16 to 64 kbps is normal. Add onto that the extra overhead of about 10 to 24 kbps. In total, VOIP uses 26 to 88 kbps. As a general rule, assume that you will need at least 88 kbps to use VOIP reliably. Note that VOIP service providers will provide you with their broadband requirements.

You will need an Internet connection that can handle at least 128 kbps on the upload side. Extra bandwidth will allow others in the household to surf the net or download files while you are talking on the phone. If you wish to use conference calls even more bandwidth will be required.

While there is no set rule for the amount of bandwidth that a household will need, count on 128 kbps as a minimum.  If you have several computers and other devices connected to the Internet, consider going up to the maximum available.

Note that these speed are for uploads – the download speeds are usually quite a bit faster and present no problem for VOIP.

Alec Saunders reviews Talkster, a new service that lets you make inexpensive cell phone calls anywhere in the world, and mobile to IM (Instant Messenger) calls. In Talkster’s words: “There are a couple of cool perks to note with the Talkster service; some of the most important being that there is no subscription to the service to buy (ala Rebtel), there is no software to download (ala Jajah), it works on the cell network you are already used to using (no 3G requirement ala Fring), and it works on the phone you already have today (not just select Java phones). It also works today, with popular IM services MSN, GoogleTalk, and Gizmo Project. In a nutshell, Talkster is the first company to enable mobile-to-PC Voice over IM (VoIM) calls, that works without software, on virtually any phone.” That sounds like something worth trying.

Alec reviews it using his Blackberry and he’s impressed by how easy it is to browse his list of contacts, view their online presence, and make calls. While the service works without software on virutally any phone that supports a browser, in reality only browser-friendly phones need apply. For example, my cell phone has a browser, but the phone itself is of the entry level variety so using the web enabled capabilities is awkward (I find). I’ll be giving Talkster a try with my basic handset and with my husband’s fancy one and I’ll add my comments to the mix.
