Free Internet phone service lets you to make free long distance calls over the Internet in three different flavors. The first enables you to make calls from one phone to another as long as both are connected to broadband lines. The second allows you to make calls from one computer to another and the third makes calls possible from a computer to a traditional phone.

But, there are limitations to free services. Let’s take a look.

Phone-to-phone service providers require that you purchase their telephone adaptor (or ATA). As long as you are calling other people who have purchased the same equipment, the call is free. PhoneGnome is one such service. The PhoneGnome adaptor costs about $119. You literally plug it in to your broadband connection and to your regular phone, it configures itself, and you are good to go. You can start calling other PhoneGnome users anywhere for free. You don’t have to switch phone numbers or change telephone companies. Vonage, Packet8, AT&T CallVantage, and others you may have heard of follow the same model.

PC-to-PC service providers allow users to make free calls from one PC to another. Both parties need a PC with an Internet connection and some software easily downloaded from the Net. However, for a call to ring through, both parties have to be online at the same time and have the same, or at least compatible, software. By adding voicemail to a PC-to-PC service though, callers can leave messages even when you’re not online. Unfortunately, voicemail may or may not be free.  Skype, Gizmo Project, and FWD are three typical PC-to-PC services.

PC-to-phone services let you to call a regular phone numbers for free. However, you may be restricted to the locations that you can call or the length of the call. VoipBuster, for example, provides free calls from your PC to landline phones in about 30 countries. The restrictions are a little bit complex, but free is free…Lucky for us, the bigger software-based phone companies are trying hard to entice users so there’s also a current wave of promotions trumpeting free calls to landline phones. Skype for example offers free calls to any phone within North America until the end of the year. Gizmo offers free calls to phones in 60 countries as long as both parties maintain an active Gizmo Project account.

In all of these cases, free Internet telephone services make money by selling credits for calling minutes to landline phones or mobiles, long distance destinations, or phone numbers not on the same VOIP service. Rates are low, however, and you can expect to save significantly over traditional long distance companies. For regular phone users to call you on your free Internet phone account, you must “buy” or subscribe to a conventional phone number. Most services allow you to buy a phone number in different locations, so if your family is in the UK and wants to phone you regularly, you can buy a local UK number that they can call for free or inexpensively.

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!

I’ve had such a great response to my earlier post, VOIP Services for Canadians, I thought it worthwhile posting again with a number of additions.

All these companies offer Canadian area codes. Some are US companies so you pay in US dollars. Testimonials (good or bad) about any of these folks are welcome:

A friend of mine recently asked about VOIP services in Canada. Like me, he started with Vonage but has decided to look elsewhere. We both live in Vancouver and want a local 604 number. I discovered that at this point, there aren’t a lot of options. Thus began a search for services that support Canadian area codes.

I found that Mark Evans, a Canadian technology blogger, has a nice list. I’ve added a few names to it here:

• Shaw Digital Phone: BC & Alberta (select areas)
• Rogers Home Phone: BC (select areas), Ontario, probably elsewhere but they make it hard to find out. You have to enter your postal code before they’ll tell you.
• Primus TalkBroadband: Canada-wide, select cities
• Vonage: Canada-wide and the only one I think that includes the adaptor for free
• Zingotel: BC, Alberta, Manitoba, Ontario, Quebec
• Bell DigitalVoice: Toronto, Montreal, Hamilton
• babyTEL: BC, Alberta, Ontario, Quebec, Nova Scotia
• Telehop Broadtalk: Ontario
• AOL Canada TotalTalk: BC, Alberta, Ontario, Quebec, Nova Scotia
• Cogeco: Ontario,Quebec
• SpectraVoice: Ontario, Quebec
• Videotron: Quebec
• unitz.ca: Canada-wide
• DigitalVoice: BC, Alberta

Added Sept. 25:

• Unlimitel: BC, Alberta, Ontario, Quebec

 

If you are really looking for the best deals in residential VOIP services, look at providers with annual subscription rates. Most VOIP providers only offer monthly plans. Vonage for example is currently offering $24.99 per month for its basic unlimited service (free unlimited calling to anywhere in NA and Europe).

But as a way to reward and attract customers, VOIP companies are adopting what cell phone companies have been doing for years: offering the latest and greatest gear for free in return for long term committment. 

SunRocket markets a similar package at $24.95 per month or an annual subscription at $199 per year. That works out to about $17 a month. So if you can handle prepaying for your service by the year instead of by the month, then an annual package is a good idea.

Packet8 has also recently adopted the annual package deal. For a flat rate of $199 per year, you get get unlimited calling within North Americal, calling features like voicemail and call waiting and a 100% discount on a Packet-8 enabled UIP1868P 5.8-GHz digital cordless phone system, which can be extended to work with multiple cordless handsets.

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.

In order to use VoIP, both parties need a broadband connection. This is a high-speed Internet, or broadband connection usually provided by a cable or DSL modem. Broadband modems are usually used to connect computers to the Internet, but in the case of VoIP, computers are not necessary.

The simplest form of VoIP is a computer-to-computer voice connection. All that is required for this type of connection is a computer, a headset consisting of earphones and microphone, and VoIP software. Most software packages are free and allow you to connect to any computer running the same software. There is no charge for this type of connection and calls can be made to anywhere in the world.

VoIP software can also be used to connect to land-line phones — that is, phones which are not connected directly to the Internet. This type of call is usually not free but the cost is quite a bit lower than what your telephone company charges. Some VoIP services also allow you to make calls to cellular phones.

The only time that both parties need a particular VoIP software package is when they are making computer-to-computer calls. Parties receiving land-line or cellular calls do not need any extra equipment or software.

VoIP Transmissions

VoIP is based on digital data transmission. The first step in any VoIP call is to convert the analog signal of the human voice into digital data. This is done within an Analog-to-Digital Converter (ADC) that divides an analog signal into discrete steps which are represented by numbers. The next step is to compress the audio data using a codec (enCOder/DECoder) which significantly reduces the amount of digital data while maintaining audio quality.

The compressed digital data can now be sent over the Internet. The data stream must be divided into packets which, besides containing the audio data, also have information concerning their destination and their place in the data stream.

All data that is sent over the Internet is encapsulated in ‘layers’ which aid in its proper delivery. For example, web pages may use the Internet Protocol (IP) network layer to specify destination and origin addresses, the Transmission Control Protocol (TCP) transport layer to create a connection between two computers and the Hyper Text Transfer Protocol (HTTP) as an application layer to allow the Web browser to display the web page correctly.

Most VoIP uses a transport layer called User Datagram Protocol (UDP) which is faster than TCP. A commonly used application layer is Real-time Transmission Protocol (RTP) — originally developed for delivering audio and video over the Internet. RTP provides information about the sequence of the data packets so they can be reconstructed in the correct order at their destination.

RTP also has the ability to drop packets if they do not arrive within a certain amount of time. This is necessary for telephone conversations because if the telephone software waited for every packet of information to arrive before reassembling it there would be unacceptable delays in the audio stream.

Even though some of the packets are dropped, there is usually still enough information to make the conversation legible. The number of packets that will be dropped depends on the speed of your Internet connection in the distance between the two parties.

Once the voice data has arrived at its destination, it is reassembled in the correct order and converted back from digital to analog.
