What is VoIP & how does it work?

VoIP, or Voice over Internet Protocol, is a communication technology that sends voice signals over the Internet rather than a traditional telephone line. It works by converting analog audio signals into digital data packets and sending them to the recipient. On the receiver’s end, the data packets are converted back into audio signals so they can be easily understood.
