You’re gonna need to unpack what you mean here because TCP/IP is the basis for pretty much everything, even modern phones
Phones, like landline phones or when you’re not using wifi calling, use a totally different method of communication than the internet. VoIP and WiFi calling do not use the phone part, they use the internet and are a completely different protocol/method.
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)
I work in telecommunications. This is pretty much exactly correct.
Not really a rebuttal to anything you said, but to expand on the fact that WiFi calling uses VoLTE “most of the time”, which is true because in some conditions SIP is used, but if you are using an Android or iOS phone, you are always using a modem, the voice line is never analog, and all digital voice communications are sent over TCP/IP.
Shame the article was talking about a mobile phone or that point would have mattered…
Currently, all phone calls made over a cellular network are monophonic, meaning audio is compressed into a single channel
This bit from the article is what I am trying to convey. Teamspeak doesn’t use whatever phones use when you make a phone call, even if it’s a cell phone. Cell phones do not have to do this. They have the bandwidth for stereo phone calls and yet, so far, they still compress it into garbage unless you’re using a VOIP app or Wifi calling on both ends.
