Primarily, there are three basic requirements for a VoIP phone system to work for you: a fast speed internet like DSL, a computer or other terminal, and an adapter. Though VoIP Phone Systems can also work on slow speed internet connections but they hinder smooth communication and annoy the users. So, it is recommended even to pause all other downloads while using VoIP. Hence a fast speed internet is the first need.
Second need is related to the hardware. A computer is typically required to use VoIP services. That means there are some specific clients who prefer not to use a computer for this purpose, in such a case the VoIP service provider may give them the necessary alternative equipment to connect with VoIP; Vonage is such a company that does not need computers to give VoIP services. However, the majority of the VoIP Phone Systems uses a computer as the terminal. The second hardware required to connect with VoIP network is a headphone to communicate with others. These headphones are available in the market or you can buy a VoIP head set for this purpose. These headsets are especially designed to VoIP functions and a VoIP services provider can give you one if you want to have one.
Software installment is the third and last need to connect with a VoIP network. Putting a glance at the top three VoIP service providers i.e. Google, Skype and Vonage; we come to know that only Skype requires its software installment to let VoIP users use its services. However, most of the VoIP service providers must their software installments for using their VoIP services. Most of these softwares are freely available for downloading.
VoIP Phone Systems are getting popularity for their affordable business communication solutions especially for small businesses and for this reason; they are called the future of business communication.
If you are paying lots of money on business communications, you can cut these bills down to a reasonable level by using VoIP services. Of course this has implications - call quality is typically very poor over the internet, and so this is seldom used in the corporate or enterprise markets.
