Communication has always been an intrinsic part of our daily needs. Be it for social or business purpose we need to communicate with others in order to put across our message or to receive it from others. A revolution in the field of communication started with the invention of telephone by graham bell. This was followed by a series of improvement in the way we network over the telephony system. In the more recent times we were able to communicate with voice being thrown over the optical fiber wires which send forth our message to the receiver. This traditional mode of communication provides a quality and reliable method of networking.

However, with rising competition and changing needs of the business and residential users there has been a niche created in the telecommunication sector for a channel of communication which will prove to cheaper than using PSTN or public switch telephony network.

A solution is given by World Wide Web which allows cost effective and quality calls to be made by using the VoIP call termination technology. The invention of this technology has brought about another revolution which has changed the very way telecommunication industry used to transmit the calls. Instead of sending calls over expensive optical network, calls are now transmitted over the Internet in the form of small digitalized packets over the Internet. Use of Internet and minimum hardware requirement is what makes VoIP service the preferred telephony service of millions.

One can either opt for a free service of VoIP or deploy paid voice over IP service. Confused as to which would be the best deal for you? Ask yourself what matters more to you; free calls or reliability, security and quality? If you would much rather get free calls then free service would fit the bill perfectly. On the other hand if you are more concerned about the reliability, security and enhanced quality then opting for the paid best VoIP service provider would be a good idea.

stand at the top of the service chain and help the voice over IP service to be available to its users through a vast network of VoIP wholesale service carriers and VoIP resellers or can even offer service directly to the users.

While reviewing a voice over IP provider ensure that they have backup routes available in case the one allotted to you stops working in order to get the benefit of uninterrupted service. For crystal clear voice quality, look around for a provider with multiple points of presence at strategic locations and multifarious switches. Direct interconnection with Tier 1 providers would guarantee ripple less telephony service.

The primary differences are that you use a different adapter and that adapter connects to the DSL router or modem rather than to a cable modem. To make your connection, follow these steps:
1. Connect the VoIP adapter box to the DSL router or modem.
2. Connect your computer to the VoIP adapter box.
3. Install the software provided by the VoIP provider.
4. Configure the telephone number and other parameters as directed by the VoIP provider.
5. Connect a microphone and speakers or plugs to a VoIP headset or handset.
6. Use the IP soft phone directly from your computer and begin to place VoIP telephone calls.
DSL does not require you to abandon your POTS telephone nor its services. Using an inexpensive splitter that plugs into the VoIP adapter box, you can, continue to enjoy POTS telephony as well as VoIP.
Potential DSL problems
The technology used by DSL requires that the distance between your computer and the nearest carrier facility be no greater than 18,000 feet (about 3.5 miles). Distance is a factor with DSL in determining overall data speed: The shorter the distance, the better the throughput. Thus, the closer you are to the carrier facility, the better the quality of your VoIP experience. If you are near the distance limit, you may not be able to get speeds that provide satisfactory quality.
DSL does not provide enough bandwidth to support VoIP traffic for a multilocation company. Therefore, DSL is not acceptable as a transport for a multisite corporate network. However, DSL is more than adequate for consumer and home-business VoIP.
