Computer Software

By the end of 2006, Voice over Internet Protocol (VOIP) may account for as much as 25 – 40% of international voice traffic. This prediction is impressive, but it is even more amazing when you consider the relatively short history of voice over internet protocol. It began as a hobby for some people in Israel who were only able to communicate by computer.

Later that year, in 1995, the first company in the history of voice over internet protocol to put a product on the market was Vocaltec. They released Internet Phone Software, which in combination with a home computer, sound card, speakers, microphone and modem allowed users to make a phone call over the internet. However, the people on both ends had to have the same setup, and sound quality was much less than on a normal phone.

In 1998, there were more milestones in the history of voice over internet protocol. Entrepreneurs began to recognize the potential of the technology and soon computer-to-phone and phone-to-phone connections (still using a computer for the transmission) were possible for making voice calls over the internet. The service was available using a phone at a provider’s location in North America only.

It required the users to listen to an advertisement at the beginning and end of each phone call, but in exchange their long distance calls were free. In 1998, less than 1% of voice calls were made using voice over internet protocol.

Businesses began to use VOIP over their intranets to help communicate within their company. But with the introduction of switching equipment in 1998 by 3 manufacturing companies, the history of voice over internet protocol took a turn towards the future.

Now VOIP could become more readily available to users at home instead of at a specific facility belonging to the provider. By the year 2000, more than 3% of voice calls were made over the internet using VOIP.

Today, there are both hardware and software options for those interested in business VOIP and for their personal use. You can purchase hardware that will allow you to use your normal phone handset when making a phone call.

You can buy phones that are VOIP ready and need only an internet broadband connection. Or, you can purchase or download software that will let you use your computer instead of a phone, provided that you have speakers, a microphone, and an appropriate sound card.

Many phone companies have begun to offer packages that include local and long distance VOIP calls for a flat monthly fee. With the advent of broadband services, sound quality has become parallel to regular land line phones for the first time in the history of voice over internet protocol. And the number of people using VOIP is only expected to grow.

Voice over internet protocol or VoIP is beginning to come into it’s own. The promise of cost savings over traditional phone lines is driving this technology into the mainstream. Leveraging your existing broadband connection to save on your monthly phone expense at first glance makes sense. Let’s take a closer look.

First off, can your existing broadband throughput handle the additional strain of digital voice transfer? You can use your favorite search engine (google, msn, yahoo, etc.) and search for ‘VoIP broadband test’ to get a general idea of the speed of your connection. This is only the first consideration.

How is your existing broadband access coming into your home? If you’re using DSL then using VoIP for your ‘primary’ phone line may not be an option. DSL availability without existing phone service is not generally available. You should check with your local phone company before canceling service. You just might end up with no phone service, VoIP or traditional. Check first.

If you’re using cable internet access and your connection speed test looks good, find a VoIP provider that allows for a trial period. You may find a good provider that offers up to 30 days for you to cancel if you are not satisfied with voice quality or service.

A VoIP converter and a router will be required to setup your VoIP service. Your modem would plug into your router. Next your converter plugs into your router and your phone base plugs into your converter. Most normal phones should work fine. There isn’t any ‘special’ phone required to use this type of service. The entire process is pretty painless, but if you should run into any issue, your provider should be ready to help.

If you’re looking to leverage your existing broadband internet access to save money on your monthly phone expense, VoIP can be a great option. Just remember to check your connection, check with your local phone provider (for DSL users) and find a provider that offers a money back trial period. This can be a great way to save money, but don’t be pressured before you know the facts. Even if it doesn’t work out for you now, keep your eye on this technology.

The FCC is already involved in the apparent conflict between VoIP service providers and DSL access. E911 service (Enhanced 911 service) is already being mandated and additional steps will be made to bring this technology further into the mainstream. Make no mistake about this technology. It has arrived and is here to stay.

In the event of an emergency, are you capable of receiving the emergency response from calling 911 that you normally expect when using a traditional phone line? In the United States as well as Canada, a 911 call placed from your telephone is routed to PSAP (Public Safety Answering Points). Your number and location are reported when this call is placed. Knowledge of the phone number allows the 911 dispatcher to return the call if necessary and the location is of obvious importance to route an emergency response team. But what happens when this same 911 call is placed over a VoIP line?

There have been reported incidents where existing 911 calls placed from VoIP don’t get through to the primary PSAP and at times are routed elsewhere. The dispatcher also wasn’t receiving the additional information such as phone number and location. This can slow emergency response services to a critical level.

The FCC has mandated that all new subscribers have access to E911 service. The Enhanced 911 service provides the same level of information to the PSAP as described above. Currently there are some VoIP subscribers who do not have this service. The
FCC originally order a disconnect for all existing VoIP users without the E911 service. Recently the FCC has backed off that order (the original deadline for disconnect was Nov 28, 2005). Instead the FCC has now mandated that all ‘new’ service be equipped with E911 service. Those remaining VoIP providers not offering E911 service will be unable to market or sell new services until such time that they implement the E911 service.

When researching possible VoIP providers, you should make sure that this service is available. The government is mandating that it be available, but as an informed consumer this is information you should know. What good is saving money on your monthly phone bill if it’s at the expense of the safety of you and your loved ones?

Other things you should keep in mind is that VoIP runs over your existing broadband connection. If your broadband connection goes down, so does your phone line. Your broadband signal also needs to travel through your modem, so in the event of a power
outage, your broadband is down as well. (because the modem would be without power). You may want to review having a battery backup in the case of power outages and perhaps a second traditional phone line or a cellular phone in order to place emergency calls.

Believe it or not, there are still a few people out there who just don’t get it when it comes to VoIP. With services like Skype, or Google Talk, it is easy to confuse what a true VoIP plan really is.

Skype, Google Talk, and the like would be more accurately described as PC to phone or click to call VoIP services. A true VoIP service uses an adaptor, enabling you to make and receive calls with your home telephone.

I think it is important people know the difference between click to call and true VoIP when deciding on a VoIP plan. For all intents and purposes we will be discussing five good reasons to buy a true VoIP plan.

The biggest reason to buy a VoIP plan is also the most obvious. VoIP is tremendously cheaper on both local and long distance telephone service, plus available calling features.

Number two on our list would be the dynamic features of VoIP phone service. VoIP enables you to have a phone number outside your own area code. You can take your adaptor with you when you travel too.

Number three is the cost effective ability to add on to existing service. Lets say you want a second phone line. With VoIP there is no need to install new equipment, and in most cases this will only cost around five dollars.

Number four is what I like to call the big trade off. By switching from dial up Internet to broadband, and switching to VoIP for phone service, you are acctually getting better service for less money.

Last but certainly not least, VoIP providers do not charge hidden fee’s. Hidden fee’s can make up to 20% of your total monthly phone bill. The only extra fee with VoIP is a 3% federal excise tax based on usage.

In closing, when looking for a VoIP service, make sure it is true VoIP. You only need a cable broadband or DSL connection, plus an adaptor to get started. Look for a VoIP company with a money back guarantee.

What is VoIP?

Chances are you’ve heard of VoIP, or “voice over Internet.” If not, you will soon, as major phone companies are now trying to get in on the action. Why? VoIP allows users to make phone calls using their high-speed Internet connection. This essentially translates into “free” long distance, or, depending on set-up, unlimited long distance for a low set price for the service. When using VoIP, the traditional phone company is left completely out of the loop–literally. The concept is much the same as email; for the price of an Internet connection and provider, you can send unlimited email messages.

VoIP Pros

VoIP is an affordable method for long distance calling, and depending on where you live, you may be able to transfer you current phone number to a VoIP system. VoIP is easy to use, and depending on the service and method you choose, installation can be as easy as downloading software or attaching an adaptor to your computer. For the most part, sounds exactly the same as with a traditional telephone line. If you are using VoIP and the other person is not, they will not know the difference.

VoIP Cons

Some areas do not yet have this availability, but it is still possible to transfer long distance only to VoIP–it just means that you’ll have a separate number for long distance calling. This may be a slight inconvenience, but the savings may offset the cost–it all depends on your needs. Also, some users report hearing an echo when using VoIP. There can also be a slight delay at the beginning of the call.

One primary issue regarding VoIP is the ability to dial out for emergencies. Some providers work to place 911 calls (by configuring your service), and some do not. If you will be replacing your landline or mobile completely with VoIP, this is something you will want to research before choosing a provider and service.

Is VoIP Right for Me?

Deciding to choose VoIP depends on your needs. If you make a large number of long distance calls, it may be well worth looking into. VoIP services are often much less expensive than traditional providers. When comparing VoIP to cell phone programs, it again depends on needs. Most VoIP packages are considerably less than cell phone unlimited calling plans, but of course, VoIP is not as flexible (yet) as far as portability and other features you may not want to give up on your cell plan.

How Do I Get Set-up for VoIP?

Technical requirements for VoIP depend on the service and method you choose to use. There are three types of VoIP options.

• ATA stands for analog telephone adaptor, and it’s very simple to use. You connect it to your computer or Internet connection, plug in a regular phone, and you’re ready to go! Providers such as Vonage and AT&T CallAdvantage use this option.

• IP phones are special phones that look like traditional phones, but they connect with an Ethernet connector. A similar phone in the works is one that operates with Wi-Fi, which means that when you take your laptop to the local coffee bar to access wireless Internet, you could also make a long distance call.

• Computer-to-computer is an easy way to use VoIP and long distance calls are free; you only pay for the software. To use this method, you will need to download and install the software and be equipped with a microphone, speakers, a sound card and a high-speed Internet connection such as DSL or cable. Aside from the software, the only fees are those for your monthly ISP.

You’ll need a high-speed Internet connection to use VoIP, such as DSL or Cable.

Most VoIP options are easy to install. Providers of ATA, for example, will usually send you the adaptor you need when you sign up for the service. If you have a standard Internet set-up, you should be able to easily install the adaptor and software yourself, and be on your way. The process is very simple and straightforward, and once installed, the service is immediate (no waiting 3-5 business days for your phone service!). Connecting an IP phone is equally easy, and computer-to-computer simply requires the downloading and installing of software.

My friend in Florida, Samuel, called me last week and immediately I noticed a difference in the sound quality compared to our usual conversations. At first, I dismissed it, thinking he was calling me from his cell phone. Five minutes into the conversation when the call suddenly dropped off I “knew” for sure he was calling on his cell. Until he called me back from his cell that is. It turned out that Samuel was using his regular home phone, but when he told me that he had a VoIP account that was all I needed to know.

What is VoIP? VoIP stands for Voice Over Internet Protocol which is a method for you to talk with someone via your broadband internet connection, cable or DSL. Your voice is translated into data and sent over the same connection used for your computer. VoIP has become popular because you can talk to people for just a few cents per minute…worldwide! In fact, in a recent ad I saw that one of the leading providers of this service is offering free calls to Canada and charging just 3 cents per minute for calls to Hong Kong and 6 cents per minute for calls to Copenhagen. People who frequently call international destinations love VoIP. Heck, at prices one-tenth the amount or less of conventional long distance rates VoIP does have a strong appeal for consumers.

Overall, plans seem to start at around ten dollars per month and increase to around forty dollars monthly depending on offerings selected. Many VoIP plans give plenty of “extras” as part of the package including:

Call Forwarding

Call Waiting

Caller ID with the name

Repeat Dialing

3-Way Calling

Voicemail

Call Blocking

911 Accessibility

I have seen plans that also offer widespread 411 accessibility, fax service, and virtual phone numbers which allow users to select phone numbers outside of their area code.

There are big drawbacks to VoIP and I learned what one of them was when I was talking with my friend in Florida: a power failure will mean that your phone will not work. My friend lives in an area of frequent lighting strikes and occasional power failures so each time there is an interruption he has to wait for power to be restored before he can call out from his home phone. Fortunately, he keeps his cell phone charged, but he does have to pay for most calls made on his cell. In some areas the savings from a VoIP account will be offset by cell phone usage.

911 calls also can be difficult to place; you may need to dial a lengthy ten digit number to the police, fire, or ambulance station instead costing you valuable time in an emergency. Some providers are working hard to overcome the problem, but it hasn’t quite been done away completely.

In all, VoIP usage continues to grow and it will probably become an important way for many to place calls, particularly internationally. You can’t stop power outages and 911 issues remain, so weigh your options carefully before making the move over to Voice Over Internet Protocol.

If you have an ear open to new computer technologies, you are sure to have heard about VoIP. Voice over Internet Protocol (VoIP) is an emerging set of applications which allows you to make telephone calls over the Internet. It is already starting to replace existing telephone networks, with some people and businesses opting to cancel their traditional phone line and use VoIP instead.

VoIP was originally developed to provide voice communication between computer users in different locations. Although it still has this application, it has been further developed into a telephone network in its own right. People using VoIP can call any telephone anywhere in the world and can receive calls on telephone sets connected to the Internet or Local Area Network (LAN).

It all started back in 1995 when Israeli computer enthusiasts made the first computer to computer voice connection. In the same year this technology was developed into a software package called Internet Phone Software. All that was needed to talk to another computer user was a modem, sound card, speakers, and a microphone.

The software digitized and compressed the audio signal before sending it over the Internet in data packets. These voice connections could only occur between computers which had the software installed. The sound quality was very poor — nowhere near the quality of standard telephone connections.

The technology continued to be developed and by 1998 gateways had been established to allow PC-to-phone connections. Later that same year phone-to-phone connections that used the Internet for voice transmission were set in place. These phone-to-phone connections still required a computer to initiate the call, but once the connection was established, the callers could use a regular phone set.

VoIP Today

There are currently many VoIP services available for residential and commercial use. Some of these still rely on PC-to-PC connections but may offer other services such as PC-to-phone and phone-to-phone.

Internet phones are available that plug into the sound card or USB port of a computer. These phones may have number pads and ringers that allow you to use them the same as traditional telephones. The computer can be bypassed completely by connecting a phone directly to a broadband modem (either DSL or cable).

How Does It Work?

The first step in using VoIP is converting your voice into digital data. This is done by ‘sampling’ your voice — dividing the analog sound signal into discrete steps that can be assigned a number value. Once your voice is digitized, the data can be compressed.

This compressed digital data is split up into ‘packets’ of about 1500 bytes that can be transferred over the Internet. As well as the voice data, the packets contain information about their origin, their destination, and a timestamp that allows them to be reconstructed in the correct order. Once they arrive at their destination, they are reassembled and converted from digital back into analog so that the receiving party can hear your voice.

In order for voice data to be transmitted without noticeable delays, a broadband Internet connection is necessary. Many households and businesses are already using broadband (either DSL or cable) so adding VoIP is relatively simple.

With VOIP technology, you can now place a phone call to someone on the other side of the world using your broadband internet connection rather than a telephone. VOIP technology, in essence, takes the analog signals from your voice and converts them into digital signals able to travel over the internet. Then, at the other end, VOIP converts the digital signal back to the spoken word. Types of VOIP service vary.

Some VOIP providers only allow you to call other users of the same VOIP provider; other VOIP providers allow you to call anyone with a telephone. To break it down, there are three basic types of VOIP service: With an ATA (an analog voice adaptor), which is box that connects your computer (or your internet connection) to your telephone for VOIP use. With an IP phone, a special VOIP phone that is by all appearances a regular telephone but with special Ethernet connectors allowing you to hook it up to your router. Before long, WIFI VOIP phones will be on the market, allowing you to place a VOIP call from any internet hot-spot.With just your computer, you can install VOIP software and place, for free sometimes, VOIP phone calls anywhere in the world.

Get a sound card, speakers, a microphone, and an internet connection, preferably broadband, and youÕre good to go. Probably one of the most apparent benefits of VOIP is how it relieves you of the need to pay the telephone company for phone service. That’s one more bill out of your life! You only need to pay your broadband bill (plus VOIP charges) to have your telephoning needs met as well, and a VOIP bill is usually much cheaper than a phone bill. If you carry an internet-enabled laptop with you wherever you go, say, on a vacation, then all you need to do is bring your VOIP adapter and/or IP telephone and you’ve got service as good as, if not sometimes better than, a cell phone.You must also consider the disadvantages before diving in and going VOIP. For one, your VOIP service may not respond well during power outages and server failures. If your internet is ever out, your VOIP will be out as well, and thus your ability to place phone calls.

Additionally, not all VOIP providers offer 9-1-1 or directory assistance calls. Before purchasing VOIP hardware and service, make sure the VOIP company you choose provides the services you need. Interestingly enough, you may have been placing VOIP calls for a long time now without even knowing it. Telephone companies have been using VOIP technology to make their services more efficient. You can also expect most of the same features from your VOIP service provider as you currently get from your phone company. VOIP service often includes caller ID, call waiting, call transfer, return call, and other convenient features youÕre used to.

Additionally some VOIP providers offer call-filtering services, letting you choose how calls from a designated number are dealt with. Maybe you forward the call to a different number elsewhere, maybe the caller gets a busy signal from you, or a message saying your number is Òno longer in serviceÓ. Some even allow you to check your voicemail over VOIP and add voice messages as email attachments.VOIP is a burgeoning technology with extremely promising possibilities ahead of it. Before long, Ma Bell may become obsolete.
