March 15, 2010 at 2:45 am Leave a comment

The rising buzzword in the Internet community, nowadays, is VoIP phone. What does it mean? How does it affect your life or business?

VoIP stands for Voice over Internet Protocol, and that means a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone.

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.

Equipment Needed

The broadband (high speed Internet) connection is the major equipment required for VoIP to work. All VoIP services require your broadband Internet connection to be active. A computer, adaptor, or specialized phone is required.

Charges Associated

Some VoIP providers charge for a long distance call to a number outside your calling area, similar to existing, traditional wireline telephone service. Other VoIP providers permit you to call anywhere at a flat rate for a fixed number of minutes or some even provide these services for free.

VoIP Advantages

There are two major reasons to use VoIP: Lower Cost  and Increased Functionality

In the most extreme case, users see VoIP phone calls (even international) as FREE. While there is a cost for their Internet service, using VoIP over this service may not involve any extra charges, so the users view the calls as free. There are a number of services that have sprung up to facilitate this type of “free” VOIP call. Examples are: Free World Dialup and Skype

VoIP makes some things easy that are difficult or even  impossible with traditional phone networks.

  • Incoming phone calls are automatically routed to your VoIP phone wherever you plug it into the network. Take your VoIP phone with you on a trip, and anywhere you connect it to the Internet, you can receive your incoming calls.
  • Call center agents using VoIP phones can easily work from anywhere with a good Internet connection.

VoIP Disadvantages

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.
  • Not all VoIP services connect directly to emergency services through 9-1-1.
  • VoIP providers may or may not offer directory assistance/white page listings.
