VOIP (Voice over Internet protocol) is a device to transfer voice over IP (internet protocol) by digitizing voice into discrete packets that are transferred independently over the network, instead of traditional circuit-committed protocols of the PSTN. Broadband phone is a familiar name for VOIP which is similar to a telephone but economical in nature. The user can directly use a VOIP through his computer or a telephone device connected to computer. The analogue electrical signal is sampled at regular intervals (e.g. 8000 times per second) and each sample is assigned a binary number - typically 8 bits long. The binary data is assembled into small packets and inserted into the data field of the IP packet and sent to the destination.
At the destination, the handset gets the IP packet including the voice data. The handset extorts the voice data and coverts the data back to an analogue electrical signal which is passed into the handset receiver. The electrical signal vibrates the receiver diaphragm loyally reproducing the audio voice signal.
Voice over Internet Protocol offers a great deal of flexibility and economies of scale. VOIP connection is very economical and easy to install. All you need is a high speed broad band internet connection. VOIP's can directly be attached to a computer or through an advanced telephone. There are also many handset software packages available so you can use your PC or laptop as a VoIP phone by connecting a low cost headset. Also, USB handsets are available for less than 10/$15. Computer must be equipped with a headphone if the user wants to use VOIP directly through his computer and not any other device.
VoIP services are more innovative and cost effective and allow any size business to handle their clients telephone calls from anywhere in the world. Over 78% of small or mid sized companies use VoIP services compared to other legacy networks. VOIP has several other benefits like call waiting, caller id, outbound caller id blocking, speed dial, last number redial, anonymous call rejection, call screening, three way calling, call hold, call forwarding, voicemail, and priority rings etc. We have staff based in France and Australia but as far as our UK customers are concerned, they are working in our office.
Initially in 2004 when VoIP was introduced in the market there was a very little or no demand for these services. But today with technical advancements and innovative ideas VoIP services are more widespread.
VOIP uses IP networks to transmit voice data; hence there is a high possibility for virus attacks and other troubles. Software weakness can be exploited and also some sensitive information could be misused or hacked. Hence VOIP is not secured and cannot be trusted to pass on sensitive or secret information. There are companies which provide some security measures without compromising on the quality or flexibility of the device.
