We have the technology required to record, transmit and play high fidelity audio and video. Why are the phone calls’ quality still so bad as if we’re talking over walkie-talkies?
In other words, we definitely \*can\* have high quality phone calls. Why is it that the carriers (or whoever responsible for building the underlying infrastructure) choose to not make this improvement yet?
Edit: the question came up after finishing a call with my bank. I’m pretty sure the CS on the other end used a landline phone and the audio quality was no bueno. Maybe my impression on the phone calls’ quality can have some recency bias involved. So please correct me if phone call qualities aren’t that bad in your region or in your experience .

One word: Ma Bell. The more you look into the weirdness of phone calls. The more you find AT&T to blame. I’m not talking about the more frustrating part. I’m talking about the 1900-1980s AT&T
