Today, more and more people are consciously making an effort to learn about Voice over Internet Protocol or VoIP. One thing that they all look for is whether or not VoIP can act as an alternative to the good ol telephone service, which has made such an impact in the lives. Can VoIP replace the humble telephone for good? One way to find out is to weigh the advantages and disadvantages of VoIP.

VoIP offers many advantages for you. Among them are:

1. VoIP is a whole lot cheaper compared to your normal landline telephone. With a residential VoIP plan you only need to pay about 9.95 for the most basic service up to about 39.95. For a business VoIP plan, the cost would be somewhere about 49.95 to 99.95 and comes inclusive with a separate fax number.

2. The VoIP modem (which is free) is delivered to you in only 5 to 10 days. Or you could buy it at your local store for same day service and get the VoIP provider to credit it against your bill.

3. The services which are considered as extras in your regular landline telephone service, such as Caller ID, Call Waiting, Call Forwarding, Voice Mail, 3-Way Conferencing, Repeat Dialling, and Call Block are now standard services with your VoIP. In short, you dont have to pay extra for these extra services. They come free with the package, including the most sought after service: unlimited calling, either local or long distance.

4. With VoIP service, there is no charge for any incoming calls, which cannot be said for US cellular service providers. The same also holds true for outgoing local calls, which depends on your talk plan.

5. With VoIP service in North America, local is always inclusive of US, Canada, some countries in Western Europe, parts of Asia, and parts of Latin America. For countries which are not already included, there are international plans available which cost a lot less than that offered by the standard long distance services providers. Another way is for you to make occasional calls without a plan, but for far lower charges per-minute compared to the usual long distance plans. For VoIP services in Europe, Asia and elsewhere around the globe, this also applies (more or less) in reverse.

6. With VoIP service, you dont need to have a computer. Just take your average phone cable from your VoIP modem and plug it into your regular desktop or portable phone.

7. With VoIP service, you can activate every phone jack in the house. First, disconnect your house internal phone wiring from the regular telephone service at the phone box outside (most probably on your front wall). Then, simply take the VoIP modem and plug it into any existing wall jack inside your house. However, this option is not available for those who live in apartments.

8. With VoIP service, you can choose your own virtual phone number in almost any area code that you wish for at a very low price (around 5). This way you can have friends and family dial a local number that will then ring on your phone. The drawback is that you cant make outgoing calls, as its not considered as a real line phone line.

9. With VoIP service you can have low cost 800 numbers. This way it will be free for people to call you and yet will not be too hard on your pockets. There are monthly rates fixed for you, but they vary according to the provider. Generally it could cost you about 5 for the first 100 minutes per month, and somewhere about 4.5 cents per minute beyond that.

10. Some VoIP service providers offer a service that could locate you called Find Me at other numbers that you provide, either in sequence or simultaneously, should you fail to answer your call. If you still dont answer, your call will then go to your Voice Mail which can be retrieved later.

11. And finally, the icing on the cake: You can take your home or office phone with you wherever you go. Just bring your VoIP modem with you, and when you get to your destination, plug it into any high-speed internet connection. You could be in a hotel room in the Caribbean, at your friends or relatives house in Paris or even at the airport. No matter where you are, one youre plugged in, you can make as well as receive calls on your regular phone number. Charges are based on your home location. You could be in New Zealand and if anybody were to call your office or home number in Atlanta, they would never know that youre not really there. And if you make calls, your regular caller ID still shows.

As with everything else, with advantages there are certain disadvantages, even for VoIP services:

1. If you utilise a cable connection for your Internet, your upline is 2 to 10 times slower than your downline. This means that, although you can hear crystal clear what the other person is saying, they may not necessarily hear you. This could lead them to hang up (as they dont know youre on the line), or to them telling you to call from a regular phone and to get off the speaker phone.

Even though VoIP companies insist that 256K should be sufficient for a clear signal, it does not seem to be the case. Thankfully there are ways to overcome this obstacle if you have a very knowledgeable VoIP support tech. Consult your VoIP service providers about this.

2. The quality of high-speed connections may vary, as it is dependant on many factors, including the number of other users on your cable line, or your distance from the nearest DSL booster node. This means that the VoIP quality may vary daily or during each call.

3. During your calls, when there is no one speaking, there is a silence that could lead the other person to think that the line has gone dead. This is especially true for those who have become so used to hearing a slight buzz when using a regular telephone. Instead of being bombarded with many people asking are you still on the line? you should first explain this silence that you will encounter at the very beginning of your conversation.

4. When using VoIP service, you may not be able to activate a new credit card, as the computer at the other end will claim that you are not calling from a home phone. The reason for this is yet unknown as VoIP providers have yet to answer this.

5. While conversing, you should never allow anyone to put you on silent hold, as the VoIP service may disconnect you when it doesnt hear anything. It assumes that you are no longer on the line, thus disconnecting you after a while.

6. If you have an upline signal that is not capable of relaying your call, and when you cannot get through, all that youll be hearing is a recording stating that Your call cannot be completed at this time, which can be very annoying if it happens often.

7. Sometimes, your VoIP service will just cease to work. How to solve this depends on your provider. Mostly it will take some unplugging and replugging of various connections: VoIP modem, router, cable connection, DSL connection. It all depends on your provider and the solution (and sequence) that they provide you with.

8. And finally, in what is the worst disadvantage among all, if you lose your Internet connection for whatever reason imaginable, you lose your telephone service. Should you decide to depend almost entirely on VoIP service, then you are strongly advised to have a cell phone with you at all times. This also works in your favour as you can set your VoIP service to call your cell automatically should you not answer your VoIP line.
