VoIP--a review

[Eivrad]

What is VOIP? VOIP stands for Voice Over Internet Protocol.So how VOIP works?VoIP services convert your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter. In addition, 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. What Equipment do you need?well you'll be needing a high speed internet connection,broadband connection to be exact.This can be through a cable modem, or high speed services such as DSL or a local area network.A computer, adaptor, or specialized phone is required.Some VoIP services only work over your computer or a special VoIP phone, while other services allow you to use a traditional phone connected to a VoIP adapter. If you use your computer, you will need some software and an inexpensive microphone. Special VoIP phones plug directly into your broadband connection and operate largely like a traditional telephone. If you use a telephone with a VoIP adapter, you'll be able to dial just as you always have, and the service provider may also provide a dial tone.Some VoIP providers offer their services for free, normally only for calls to other subscribers to the service. Some VoIP providers charge for a long distance call to a number outside your calling area, similar to existing, traditional wireline telephone service. Some of its advantages are its services that offersf eatures and services that are not available with a traditional phone,or are available but only for an additional fee. You may also be able to avoid paying for both a broadband connection and a traditional telephone line. If you're considering replacing your traditional telephone service with VoIP, there are some possible differences: Some VoIP services don't work during power outages and the service provider may not offer backup power.
