> I get your point but the phone companies wouldn't be able to survive Do we need them to survive? They can and should go the way of the dodo and leave place for ISPs instead. > and when I talk to people on wifi it's never as good as a phone call That's a side-effect of crap Wi-Fi gear, but can be resolved by placing the call over LTE and using stuff like MPTCP to combine both the Wi-Fi and LTE connection. In fact, VoLTE is essentially SIP (which is IP-based) over LTE, so there's a good chance you're already using an IP system and not realising it, which I guess proves the point that it's good enough if not better than legacy circuit-switched calls.
