VoIP is an acronym for ‘voice over the internet protocol’.  Basically, VoIP represents any phone call that takes place over the internet, rather than using landlines or mobiles towers. Skype, Google voice and Face Time are just a few examples of popular VoIP services. They are being used both by companies and consumers.

What is VoIP?

VoIP telephony and VoIP solutions have first been developed in the 2000’s.

VoIP is a technology used for delivering different data from a source to a specific destination using the IP protocol. The data can also include voice communication, files, pictures, fax or multimedia messages. But the main purpose of VoIP remains that of making telephone calls. Telephone calls made with VoIP are almost free of charge.

Traditionally, when you make calls by dialing on a telephone or cell phone, you are using the PSTN (public switched telephone network). With VoIP on the other hand, your voice information is converted to a digital form that is transportable through the internet.

If you have a reliable internet connection, you can get the phone service delivered through your Internet connection instead of from your local phone company. Some people also use VoIP as an addition to their traditional phone service.

What do you need in order to use VoIP?

VoIP is available in a wide range of services. Some basic free VoIP services require all parties to use their computers in order to make or receive calls. Other VoIP services allow you to call from a traditional telephone handset or from your cell phone to any other phone.  

To use a VoIP, you need a broadband Internet connection, a traditional phone, an adapter and VoIP enabled phone or VoIP software on your computer.
