TexMexBazooka , 22 days ago Alrighty let’s learn some vocab POTS lines, aka plain old telephone system, are what you’re referring to when you say landlines When you’re calling off of Wi-Fi, most of the time you’re using a technology called VoLTE- Voice over LTE, which still functions on top of TCP/IP The difference that matters here is the VoIP and VoLTE, as well as Wi-Fi calling are all digital protocols over TCP/IP networks. If you really wanna get specific, most digital phone systems use protocols called Telephony, and SIP(session initiation protocol)
