Before VoIP calls came into existence, communication was much costlier at the start of the 21st century. Internet connectivity was limited to typing texts and sending emails. With the evolution of technology, communication became more real-time, though it was still finite to talking over text messages.

The Internet revolution in the later years completely transformed the way how we connect with people around the world. The internet has become so advanced that it’s now possible for people to interact online by using their voice. This technology, in simple terms, is called VoIP.

Less than two decades old, Voice Over Internet Protocol or simply VoIP has seen tremendous growth in the past few years. It is a technique that allows users to make phone calls through their computer or phone by using the Internet as the medium.

Voice Over Internet Protocol uses a series of hardware and software combinations which enables users to send voice as packets of data online using IP, and not by traditional circuit transmission of PSTN.

 How do VoIP works?

VoIP technology uses codecs to convert audio into packets of data. These data packets are then transmitted over the internet by using suitable hardware devices. At the receiving end, the original audio signal is later recovered from these data packets, producing crystal clear voice quality.

Codecs help in compressing the data for faster transmission; as a result, the voice quality is improved. These codecs encode the analog audio signals into digital, which after transmission are again decoded to original analog form.
