Telephone systems have been an essential aspect not only for businesses but also for homes. Millions of residence all over the world have their own telephone systems for quite some time already. It is the one form of communication that people cannot do without then and now.

However, consumers have been complaining about their bills because of the high charges telecommunication networks impose on long distance calls. As a result, they prefer to disconnect their phones and prefer to use other ways of communication such as electronic emails or simply sending text messages using cellular phones. Because of this, telecommunication networks offer promos and discounts in order to regain the trust of their consumers.
    
A new technology called VoIP, also known as Internet voice or Voice over Internet Phone, allows you to make telephone calls using a computer network and over a data network like the Internet. VoIP converts the voice signal from your telephone into a digital signal that travels over the internet then converts it back at the other end so you can speak to anyone with a regular phone number.

When placing a VoIP call using a phone with an adapter, you will hear a dial tone. You can dial the number the same way you do with telephones. VoIP may also allow you to make a call directly from a computer using a conventional telephone or a microphone.

This telephone system is very much applicable for home use. You can afford to have VoIP as long as you have a computer handy. Of course, you will be needing broadband or high speed Internet connection since it is required.

This can be through a cable modem, or high speed services such as DSL or a local area network. You can hook up an inexpensive microphone to your computer and send your voice through a cable modem or connect a phone directly to a telephone adaptor. Your VoIP will ring like any other call so you would know if someone is calling you.

You may also be able to use your VoIP service wherever you travel as long as you have a high speed Internet connection available. Some VoIP providers offer their services for free, normally only for calls to other subscribers to the service. Your VoIP provider may permit you to select an area code different from the area in which you live. Meaning, you may not incur long distance charges if you call a number in your area code regardless of geography. This is also applicable to the person calling you.

Your calls might be limited only to other subscribers of the service or you may be able to call any phone number, anywhere in the world. This is depending upon the service you chose. The call can be made to a local number, a mobile phone, to a long distance number, or an international number. You may even utilize the service to speak with more than one person at a time. The person you are calling does not need any special equipment, just a phone.

With many VoIP plans you can talk for as long as you want with any person in the world. However, the requirement is that the other person has an Internet connection. You can talk with many people at the same time without any additional cost.
