VoIP, acronym for Voice over Internet Protocol, is a common term used for a group of technologies involving transmission. This protocol is used to deliver voice communications across the internet protocol networks such as various packet switched networks like the internet.
VoIP is often referred to as Internet telephony, or IP telephony, and even voice over broadband. This protocol basically is a type of communication service that involves facsimile and voice messaging techniques and applications that are transmitted via the internet. These do not take help from the public switched telephone network (PSTN). The voice signal that is actually in analog form is first converted into a digital format and then the signal is translated into a format compatible with the internet protocol so that they can be successfully transmitted via the internet. This is the technique used at the transmitting end. At the receiver end these internet protocol packets that are received as digitized signals are converted back into analog form and sent to the receiver.
VoIP is a widely used technique of modern times. You can get connected to VoIP service providers by three primary ways: by an Analog Telephone Adapter, by using the Ethernet or Wi-Fi technique and by means of a softphone or a digital phone. VoIP has many advantages which have made it a successful service. It has high bandwidth efficiency and the cost of transmission is quite low. It also enables the performance of tasks and provides such services that are difficult to be implemented using PSTN making them highly flexible.
However VoIP is prone to internet attacks or what we commonly say that data can be hacked by experts and hence it is not a very secure technique. This problem has been taken into consideration and the government and certain military organizations are now using Voice over Secure IP (VoSIP) to protect data which is a modified version of VoIP

The UK phone users may need an RJ11 adaptor to convert their standard BT Connector to an International Connector. RJ11 adaptor may be bought with a VoIP Phone Adaptor.
Broadband routers have built-in VoIP and can also be used as VoIP Phone Adaptors. You can buy these routers online.
What are the things required to avail the benefits of VoIP service?
VoIP hardware: voip phones can be plugged it straight into a network or a broadband router voip adaptors used when you need to avail voip service through an analogue telephone voip-compatible router provide access to the Internet for multiple devices (can be wired or wireless) softphone a software-based phone that operates from a PC uses Internet connection to make VoIP calls can be used with a USB Phone or PC Headset
