The Pros and Cons Of VoIP

The Advantages of VoIP
  • You receive incoming calls to your VOIP phone no matter where you are in the world. The caller always dials the same number (that you are assigned, when you sign in with the provider) and you receive the calls in whichever part of the world you are in.
  • Low cost. If you have a broadband Internet connection (DSL or cable), you can make PC-to-PC phone calls anywhere in the world for free. You can make PC-to-phone calls as well which is free of charge .
  • Portability. Carry it wherever you go! While traveling, as long as you carry headset and use your laptop plugged into the Internet, or plug a VOIP phone directly into the Internet connection , can talk to whomever you want for almost absolutely nothing. If you don't have a VOIP phone, use an analog terminal adaptor (ATA) to connect a regular phone to the Internet. An Internet phone is also small and light and hence portable.
  • Features. Usually VoIP comes with a horde of advanced features like call forwarding, call waiting, voice mail, caller ID and three-way calling .And unlike regular phone service these come at no extra charge. You can also send data such as pictures and documents at the same time you are talking on the phone.
The Disadvantages of VoIP
  • There is no service during a power outage. The regular phone is kept in service by the current supplied through the phone line, whereas in VoIP phone, there is no service when the power goes out. But,you can compromise with the use of battery backups or power generators to provide electricity.
  • You cannot make Emergency 911 calls. Traditional phone equipment can trace your location. However, because a voice-over-IP call is basically a transfer of data between two IP addresses and not physical addresses it is not possible to determine where your VoIP phone call is originating from.
  • Because VOIP relies on an Internet connection, bad or unreliable internet connections can result in poor voice quality, such as clipping, voice delay, or dropped calls your VOIP service will be affected by the quality and reliability of your broadband Internet service.
  • In some cases even the limitations of your PC can affect the quality of your VoIP service.
Well, its up to you now to make a decision!

Internet Telephony or VoIP

Internet telephony is your answer! Internet telephony or VoIP (Voice over Internet Protocol) practically eliminates long distances charges. It allows you to make local, long-distance and international telephone calls via the Internet for the cost of a local call. Moreover it allows you to commune verbally, rather than type messages. But then, the audio quality may not be as clear as the regular phone line, but then, you do save pots of money on phone bills.
What exactly is VoIP?
VoIP or Voice over Internet Protocol, is basically telephony services over the Internet using IP (Internet Protocol) network. Instead of using traditional phone land lines to make voice calls , you use broadband Internet connection .Thus you by-pass the telephone company services and charges.
All that you need for VoIP are :
· Broad band internet connection.
· Equip your computer with a sound card and microphone.
· Equip your normal phone with a VoIP adapter called ATA(Analog Terminal Adaptor).
· Use a stand-alone VoIP phone (IP phones has built-in ATA function and connect directly to the broadband modem).
VOIP phone calls can be made three ways:-
1. Computer to computer.
For a computer-to-computer voice connection you need a computer with sound card, a headset consisting of earphones and microphone, and some VoIP software. There are many free software packages available which allow you to connect to any computer running the same software. These types of calls can be made to anywhere in the world free of charge!

2. Computer to Phone.
For a computer to phone connection, you also need a VOIP software, headset,earphones and microphone,whereas the recipient on the other end can use any regular traditional land-line phone or cell phone. These phones are not connected to the Internet.

3. Phone to Phone.
For a phone to phone connection there are two options:-
· Use a regular phone plugged into an ATA adaptor, which in turn is plugged into your broadband modem.
· Use an IP phone or V0IP phone that is plugged directly into your broadband connection. IP phones have built-in ATA function.
Wireless "hot spots" in locations such as airports, parks, and cafes allow you to connect to the Internet and may enable you to use VoIP service wirelessly.
