In today’s digital age, the way we communicate has undergone a significant transformation. Gone are the days of relying solely on traditional cellular networks for making phone calls. With the advent of Voice over Internet Protocol (VoIP) technology, it is now possible to make phone calls using Wi-Fi only. But how does it work, and what are the benefits and limitations of this technology? In this article, we will delve into the world of VoIP and explore the possibilities of making phone calls with Wi-Fi only.
What is Voice over Internet Protocol (VoIP)?
Voice over Internet Protocol (VoIP) is a technology that allows users to make voice calls using the internet. Instead of relying on traditional circuit-switched telephone networks, VoIP uses packet-switched internet protocols to transmit voice communications. This means that voice calls are converted into digital data packets and transmitted over the internet, allowing users to make calls from anywhere with a stable internet connection.
How Does VoIP Work?
The process of making a VoIP call is relatively straightforward. Here’s a step-by-step explanation:
- Signaling: When a user initiates a call, the VoIP software or app sends a signaling message to the VoIP server, which then connects the call to the recipient’s phone number.
- Voice Encoding: The user’s voice is encoded into digital data packets using a codec (coder-decoder).
- Packet Transmission: The encoded data packets are transmitted over the internet to the recipient’s VoIP server.
- Decoding: The recipient’s VoIP server decodes the data packets and converts them back into an audio signal.
- Playback: The audio signal is played back to the recipient through their phone or computer.
