It's the combination of wireless packets dropping and the audio having to be degraded to 8bit/8kHz to pass between carriers that really brings on the terrible. It's kind of like TCP over TCP [1] -- works well enough a lot of the time, but when it fails, it fails badly because of how the two layers aren't really built for each other.

POTS lines do not carry more audio bandwidth than a cell phone. All of them are 64kbit PCM uncompressed audio.
