What is Wi-Fi calling and how does it work?
Wi-Fi calling, also known as Voice over Wi-Fi (VoWi-Fi), is a technology that allows users to make and receive phone calls using a Wi-Fi network instead of the traditional cellular network. This technology uses the internet to connect calls, allowing users to make calls from anywhere with a stable Wi-Fi connection.
Wi-Fi calling works by using a technology called SIP (Session Initiation Protocol) to connect calls. When a user makes a call, their phone sends a request to the Wi-Fi network, which then connects them to the recipient’s phone. The call is then transmitted over the internet, allowing the two parties to communicate. This technology is especially useful for users who have weak or no cellular signal in their area, as it provides an alternative way to make and receive calls.
