How Does Wi-Fi Calling Work?
Wi-Fi calling uses a technology called SIP (Session Initiation Protocol) to establish and manage phone calls. Here’s a step-by-step explanation of how it works:
- Your phone detects a nearby Wi-Fi network and connects to it.
- Your phone sends a request to the Wi-Fi network to initiate a call.
- The Wi-Fi network forwards your request to your phone’s VoIP server.
- The VoIP server processes your request and connects you to the recipient’s phone.
- The call is established, and you can communicate with the recipient as you would with a traditional phone call.
