Clarity and latency are at odds here. Digital can, with enough bitrate, encode more clarity than your ear can hear. Radio stations use two-channel ISDN for remote studio links so it sounds like the interviewer and interviewee are in the same room, sometimes you'd never know they aren't unless they announce it.
But ISDN is all but gone, and all other digital voice systems are packetized and suffer awful, terrible, excruciating, reflex-fumbling latency. No matter how clear they are, I'm forever tripping on — no you go — okay as I was — go ahead — um okay — aaaaaaaaaaaaargh!
> ISDN-BRI never gained popularity as a general use telephone access technology in Canada and the US, and remains a niche product. The service was seen as "a solution in search of a problem", and the extensive array of options and features were difficult for customers to understand and use. ISDN has long been known by derogatory backronyms highlighting these issues, such as It Still Does Nothing, Innovations Subscribers Don't Need, and I Still Don't kNow, or, from the supposed standpoint of telephone companies, I Smell Dollars Now.
Wow, that explains everything why Americans insist that analog is the way. I will always miss ISDN, but the march of technology insist on IP I guess.
