More Control On How You Use Your Phone
More Control On How You Use Your Phone
Still another VoIP advantage is that the VoIP telephone system offers many features which no telephone system could do. Choosing any area code, directing the calls to email when you are busy are some of the many VoIP features which allow you to use your internet telephone with amazing flexibility.
Is VoIP All Cakes And Roses?
Along with VoIP benefits , there is some VoIP disadvantage also.
Like any emerging technology, VoIP in its infancy suffered from some disadvantages such as the inability of making 911 emergency calls and poor voice quality.
The 911 issue has been solved to some extent with E911 feature in the VoIP telephone system. And the quality of voice is now as good as that of the regular phone call with most VoIP providers.
Some issues remain but they are more in the nature of limitations rather than its disadvantages. But the VoIP technology has made big strides in a short time, and it should get better, if not perfect, as the research progresses. So you can certainly expect to see more voip benefits and features in the coming days.

More VoIP Benefits
VoIP would be anyone's choice even if the only benefit with it was its low rates. But it has other advantages too - most notably its mobility. That is, take it where you want without any hassles.
You cannot take your regular landline telephone anywhere away from your home or office. If you change residence you have to apply to the telephone company to make the change which could take a lot of time. And there is no way you could take your phone when you are traveling.
If you are not using VoIP, the best you can do on a business trip or vacation is to take your cell phone with you and pay the roaming charges or use the local phone service to make your calls.
Not so with a broadband phone.
Just take your Internet Phone and adapter or the IP phone with you anywhere in the world, plug it into a broadband connection and you can start talking at the same low rates as you did at your home.
Yes, you need to pack the internet phone equipment with your luggage now, but WiFi phones will soon solve this problem too. WiFi phones which have started coming into the market are like regular cell phones with the difference that they work on VoIP.
VoIP Benefits
Money Tops the List of VoIP Benefits
Speaking of VoIP benefits, the first thing that comes to mind is that VoIP is unbelievably cheap.
Could you think of calling London, Paris or Moscow for as little as 2 to 3 cents a minute with the regular telephone companies? No way. But with VoIP, these are the usual rates.
Shop around and you should find lots of other VoIP service providers offering various calling plans suited to your requirements. While rates and features may differ slightly among them, one thing is common to all. All let you save a ton of money on your telephone bill. Most also let you make any number of free calls to anyone who uses the same VoIP service provider as you.
And, of course, you can make totally free calls if you and the person you call have internet connections.
VoIP Providers
Choosing Your VoIP Provider
If you want to give the VoIP a try, it is not the question of where to find a VoIP provider but which one to go for. This is because lots of VoIP service providers are on the market with varying prices, features and service coverage areas.
So the decision turns largely on what you want to do with VoIP service, such as Switch to Broadband Phone altogether or Use VoIP as an additional means to make calls.
Switching To Broadband or IP Phone
If you want to switch from your existing traditional telephone to a broadband phone, a number of well-known broadband service providers are there to choose from. Which one to go for depends on what are your calling needs.
For example, if you are using your existing phone mostly to make local or national calls with an occasional international call, then you would do well to go for the plan which offers unlimited domestic dialing for a low monthly charge.
On the other hand if you have to make a lot of international calls for your business, you can save a lot of money with business type of plans which allow you to make international calls for as little as 3 cents a minute to a large number of countries, with a little more for other countries not covered in the plan.
Such plans also include the facility of getting local numbers in other states or international destinations so that people calling you from outside your state or from international destinations have to pay only local charge.If you don't want to switch to a VoIP telephone, but still want to use VoIP to make calls, you have two options:
- Make computer to computer or Pc to Pc calls.
- Make computer to phone or Pc to Phone calls.
Pc to pc calls are free while you may have to pay a small charge for making pc to phone calls though you can make free pc to phone calls also with some VoIP service providers. Though there are some limitations to this type of VoIP, this is the cheapest way to call your friends and relatives all over the world - no monthly commitments or need to buy any special equipment. Moreover the number of VoIP providers which offer such service is so large that you can pick and choose the one that is most suitable to you.
Future Outlook
WiFi phones have a great potential because they allow you to make cheap or free calls while you are on the move. This is why they have become highly popular in the short time they have been on the market.
What keeps WiFi phones from being accepted as a reliable means of communication at all times is the absence of a country-wide hotspot network like the cellular network.
However, a step in this direction is that many cities are developing city-wide WiFi networks and increasing number of cafes, airports and public places are providing the free or cheap hotspot facility.
Another development that should help WiFi phones gain wider acceptance is the recent introduction of Dual-Mode Phones (see box). With these phones you are assured of on-going connectivity while enjoying the benefits of WiFi phones when you are in the hotspot coverage area.

WiFi Phone - VoIP In Your Pocket
What Is A WiFi Phone?
A WiFi phone is an internet or VoIP phone which looks and works very much like a regular cell phone. Like a cell phone, it sends and receives voice signals by radio waves, has a printed circuit board to connect its various components, needs a battery for working and, like a cell phone, you can carry it around with you.
The difference between a cell phone and WiFi phone is that a cell phone is connected to the cellular network through signal towers while the WiFi phone uses the WiFi hotspot network to connect to the internet and then work as any other internet phone.
In this way a WiFi phone is just like any other internet phone, though they work differently.
How A WiFi Phone Differs From Other Internet Phones
Both WiFi and other internet or broadband phones use internet for making VoIP calls, the difference lies in how they connect with the internet.
When you make VoIP calls by your internet phones using a handset or a headphone and speakers, your phone or computer are physically connected to the internet line through your modem and routers.
But a WiFi phone is not physically connected to internet. It accesses the internet wirelessly by what is called WiFi (Wireless Fidelity) network hotspots. So you can use your WiFi phone while you are walking around in your office or riding your car.
How A WiFi Phone Works
A WiFi phone has an internal device NIC (Network Interface Card) to detect radio waves in the surrounding area. When you try to call somebody on your WiFi phone, the NIC tries to seek radio waves from a nearby hotspot. If a strong signal is found, your WiFi phone asks permission to be allowed to login to the internet and then the call goes through like any other VoIP call.
If you are using your WiFi while driving, you would do well to park your car while making the call. Because the range of a hotspot is limited. So if you move out of the hotspot coverage area, your WiFi phone will stop working until it enters the coverage area of another hotspot on the way. This would also mean that you will miss any phones that may come to your WiFi phone. One way to get around this problem is to use the dual mode phones (box) which switch to the cellular network when they are out of the hotspot range.

One way to get around this problem is to use the dual mode phones (box) which switch to the cellular network when they are out of the hotspot range.
Internet Phone
Internet phone is a more flexible VoIP solution. Here your regular telephone turns into an Internet Phone (also called a Broadband Phone) when you connect it to your internet connection through an additional piece of hardware called ATA (Analog Telephone Adapter).
ATA converts the voice (analog) signals of your phone into digital signals which then are carried over the internet. In most cases you get this device free when you sign up with a VoIP service provider which may use other name to describe it but essentially its function is the same: to convert your voice into digital signals.
With an analog adaptor in place, you dial a number on your regular phone in the usual way. What happens is that now your voice is carried over the internet instead of the traditional telephone network. When you talk with somebody on an Internet Phone usually he cannot tell the difference that you are calling from a VoIP phone because the voice quality has improved with the advance in the VoIP technology. Another factor that contributes to the improvement of voice quality is that you are using your handset instead of a headset or speakers and a microphone.
IP Phone
This is an improvment over using your regular phone to make a VoIP call. IP Phone is an exclusively VoIP phone which looks like an ordinary telephone but has all the software and hardware components needed to make a VoIP call already built into it. Just connect this internet phone with your internet connection and you are ready to make VoIP calls. IP Phones work on different protocols such as MGCP, H.323 and SIP (Session Initiation Protocol). Of these the SIP Phones are becoming the standard.
VoIP Phone - Your Phone On The Move
As these broadband phones connect directly to the internet connection, you do not need to keep the computer on while making or receiving phone calls.
Another advantage with these phones is that you can access the VoIP phone system from any internet access. Take your regular phone and an adapter or an IP Phone with you while traveling and you can make VoIP calls from a broadband internet outlet in your hotel or a WiFi hot spot - this is something which is not possible with your traditional phone.

Limitations of Pc-to-Phone VoIP
Pc-to-Phone voip by a Softphone is a big improvement over Free VoIP. You can call any number any time you want. No need for the other party to have a computer or wait for your call. But like in Free VoIP, you have to keep your computer switched on while you are talking. And other people cannot call you on this VoIP phone, though some VoIP providers provide such a facility.
For example, if you go for the SkypeIn plan of the from Skype, you get a special number which you send to your friends. When they dial this number, your phone rings if it is connected to the computer and internet at that time. The call is directed to voicemail, if you are not online. This is one of the many special features of VoIP services.
Even if you don't go for such special plans, the softphone is a great way to use VoIP to call all your friends and relatives for pennies.
Call Any Number by Softphone
With Pc-to-Phone VoIP or softphone, you can use your computer to call any local or international landline or mobile phone. Pc-to-Phone VoIP is called softphone because it is a software-based VoIP solution like Free VoIP. This VoIP solution runs on the software that you download on your computer. Like Free VoIP, here also all you need is a broadband or DSL internet connection, a headset or speakers and microphone.
What is different, however, is that you have to pay for calling landline phones - but the rates are so low that using the softphones is as good as free.
Most VoIP providers offer this cheap VoIP service. For example, Skype has a SkypeOut plan for calling landline phones all over the world. Its rates are very low but do look around and compare rates because rates can differ for different destinations with different VoIP service providers. Also visit the VoIP forums to find out what the actual users have to say about the services of various VoIP providers.Limitations of Free VoIP
The totally free VoIP service has certain limitations:
You can talk free only with those people who are using the same downloadable voip software as you. This is one downside of free pc-to-pc VoIP. To overcome this problem, some VoIP providers have peer to peer arrangements with other specific providers by which you can call users of other VoIP providers. But this arrangement is not universal yet.
Another thing with pc-to-pc free VoIP is that the person whom you call should be online when you make the call - this means that you may not be able to reach the other person any time you want as you can do with a regular telephone. This is the main disadvantage of free pc-to-pc VoIP.
And naturally you cannot call someone who doesn't have a computer.
Here is where Softphone (PC-to-Phone) and Internet Phone (Phone-to-Phone) VoIP comes to your aid.
With these you can talk to anybody with a regular telephone anytime you want. And they are almost free compared to what you are used to paying for the use of your traditional phone.
Near zero cost of Internet Phones is enough to make them attractive any day but most have other features that are even far more attractive and which no traditional phone can provide. This is the reason of the growing popularity of VoIP.

How To Find Free Internet Phones?(SKYPE)

An additional piece of software converts the voice (analog) signals of your phone to digital signals which are carried over the internet. You dial the number from your regular phone and the person you call doesn't feel the difference that you are calling from a VoIP phone because the voice quality with this solution is generally better than a software-based or softphone.

IP Phone
This is the most flexible VoIP solution - the ultimate in VoIP telephony.
It is a special VoIP phone. It looks like any normal phone but all the software and hardware needed to make a VoIP call is included in the IP Phone. You don't have to keep your computer switched on to use this phone because it connects directly to your internet connection through a router device.

How Packet Switching Saves You Money
Packet Switching is a system that allows the VoIP to carry the useful voice data in form of packets and transmits them, one at a time, to the other end.
This means that only useful voice part is transmitted over the internet and the useless silence part is left out. During a VoIP call, the connection between two parties of a call opens only when a packet is sent or received. This naturally makes for a lot of savings in the bandwidth usage.
In this way Packet Switching has a distinct advantage over the traditional telephone connection which remains open all the time a conversation goes on.
It is because of the efficient use of bandwidth resources by packet switching that cheap VoIP service is possible. This is the main reason how the VoIP providers can offer you various VoIP solutions free or almost free.

How VoIP Works
When you call someone by a VoIP telephone, your voice (analog) signals are converted into digital signals which travel over the internet. These digital signals are converted back into voice (analog) signals at the other end and heard as normal voice by the person you call. This may sound as yet another way to send and receive voice signals much like the normal telephone network. But it has certain advantages:
- When you talk over a VoIP connection, you are using internet instead of the telephone cables. Therefore you don't have to pay for the charges of a telephone company.
- When you talk to somebody, the other person listens to what you say and then replies. Then you remain silent and listen.
In this way there are always silent patches during any conversation. On a normal telephone network, these 'silent patches' are also carried over the cable lines for which you have to pay the charges.
This is because the traditional network cannot tell the difference between useful transmission of voice and useless "silent patches". But the VoIP does. It cuts out useless parts by Packet Switching, saving you unnecessary charges.
What Is VoIP?
VoIP stands for Voice over Internet Protocol. In simple words, this means that when you make a call to someone by a VoIP phone, your voice is carried over internet, instead of the regular cable lines. When the other person replies to you, his/her voice reaches you by internet in the same way.
In this way VoIP is a telephone connection that uses internet instead of the regular telephone network.
