Detailed explanation-1: -Wi-Fi calling works through transmitting the same cellular data packets as Wi-Fi VoIP through a Wi-Fi connection and across the internet. From the internet, data is passed to the cellular network and then back to the answering party. Wi-Fi calling must be supported by the smartphone to work.
Detailed explanation-2: -Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.
Detailed explanation-3: -Are SIP Calling and WiFi Calling the Same? While SIP calling is similar to WiFi in that it also involves using a protocol to open and close connections as needed, WiFi calling actually relies on SIP protocol to connect your call.
Detailed explanation-4: -In addition, all the Wi-Fi calling packets, which may be sent through insecure networks, shall be delivered via the IPSec (Internet Protocol Security) channels using ESP tunnel mode between Wi-Fi calling devices and the cellular network infrastructure.
