Basically there aren't many phone calls over non LTE based services. Especially since VoLTE can be used over WLAN via Wlan calling techniques. (the latter isn't supported in all networks.)
I think the problem is that with "analogue" each jump can use a hodgepodge of their own voip going from Analog -> Digital -> Analog. So you can get multiple, lossy compressions with varying settings multiplied together. With user-initiated voip, it's a single compression over the whole connection. So it could be better than user-initiated voip, or a lot worse.
At least that's my laymen's understanding of legacy phone systems.
VoLTE (Voice over LTE) have some other advantages over other calling applications. VoLTE is most likely on a very high QCI (priority), which means it probably has less delay and less packet loss than other traffic. VoLTE also often uses header compression over the air which means the packets gets a lot smaller and therefore also reduces packet loss. I don't think VoLTE usually have very high bitrate though, maybe around 10kbit/s. This is one area where other apps could be a lot better.
EDIT: I am of course only speaking about mobile calls. For landlines I agree that other applications provide better quality.
1. I'm not sure if people are universally incapable of talking like that, ie. with a bit of self-restraint and without cutting in at every opportunity. I'm not sure, but I strongly suspect that this is related to the culture of people involved. As an example (or an anecdote) I work remotely full-time and participate in a lot of conference calls, yet I was interrupted just a couple of times. Never twice by the same person, though.
2. People are able to talk (and communicate) in so many different circumstances and environments, like over the radio, on a boat during a storm, on paper, with a flashlight and Morse code... that I don't think it's that hard for them to assimilate yet another protocol to follow when talking. It really shouldn't be impossible, I think.
I really strongly suspect it's a matter of culture. I was taught, from a very young age, that interrupting someone when they're speaking is simply rude, and that if you respect someone enough to talk to them, you should also respect them enough to let them say whatever they wished to say.
It's also true for many of my acquaintances, at least those from my generation and older. People who talk too much, too often and are unable to let others finish what they're saying are regarded as hyperactive, perhaps with ADHD, or really bad marketers, sect recruiters and such. This is still just an anecdote, but it at least shows that it's possible for groups of people to use a different mode of talking.
An honest question: listening what the person has to say from start to finish is so tightly correlated (in my mind) with respect for that person, that I never considered that you can get interrupted, possibly many times in a row, and not feel offended. What do you think about this notion? Do you think that it's a speaker fault if he's out of words for a few seconds, and is responsible for maintaining a steady stream of speech from start to finish? In other words, how do you justify people cutting in? Or is that simply a non-issue to you?
Rude people with poor manners is orthogonal to this issue.
After thinking it through while writing a sibling post, I now think that it's very probable to depend on a country. I think people from (to give an example I'm familiar with) most Warsaw Pact countries may be able to tolerate doing this much better than people in countries accustomed to high-quality products and services.
Or it may be just a kind of bubble I live in or something, I'm not entirely sure :)
Conversation is a fluent flow. It isn't always quick, but it's often constant. There's a rhythm. Break the rhythm, and you're breaking the expectations of your conversational partner.

I was taught that avoiding interruption was a sign of respect, as well. Do you actually get offended if someone interrupts you without meaning to?
> Do you think that it's a speaker fault if he's out of words for a few seconds, and is responsible for maintaining a steady stream of speech from start to finish?
Usually being the one at a loss for words myself, my answer is "yes". If you don't make some signal that you're working on formulating a response, you can reasonably expect someone else to jump in and fill the space. I don't feel that it's something that needs justified; one can't really "justify" social norms.
That's kind of my point! Talking over a weak connection is a situation which warrants making that "length of time" longer. My argument is that doing so is not a big deal, not hard to learn, and quite a practical (if temporary, hopefully) solution to problems with the transmission during calls.
> Conversation is a fluent flow. It isn't always quick, but it's often constant. There's a rhythm. Break the rhythm, and you're breaking the expectations of your conversational partner.
Yes, that's all true, but I don't want to break the flow, just slow it down a little. If we both know that we're talking over an unreliable connection, is it really that hard to adjust and give your partner additional few seconds in cases where you suspect they not finished yet?
> Do you actually get offended if someone interrupts you without meaning to?
I'm not sure. As I said, I don't have much experience with this kind of situations. But I think that, if I said (when joining the conversation) that "I use a rather bad connection right now and I'd like to ask you guys to take that into account if I happen to fall silent for a second, sorry for the inconvenience" and still got interrupted many times in a row, then I guess yes, I'd feel somewhat offended (that may not be the best word for it, though, but I'd feel rather uncomfortable).
My reasoning is that we're all adults, we know that the technology we use is imperfect but decide to use it anyway, so we should learn to mitigate the problems with it. They may get solved one day, maybe even soon, but, in the meantime, we can make the experience much better by ourselves. (Now I'm seriously considering if that kind of mentality seems natural to me because of being brought up in a country behind an Iron Curtain, where nearly everything by default was crap and you needed a lot of creativity and skill to make these damn things even usable. Interesting thought.)
> Usually being the one at a loss for words myself, my answer is "yes". If you don't make some signal that you're working on formulating a response
Yes, but that's assuming nearly perfect connection at all times. But we know we're using something that can be rather shitty at times, so we should just adjust accordingly. Or rather, I have a hard time understanding why wouldn't you want to do just that. Isn't it frustrating to get interrupted (even if only by mistake) constantly?
Anyway, returning to the beginning, the various "parameters" of a spoken discussion, like how long you wait for your partner to start responding, how long you wait to ascertain they're done speaking, how loud you need to speak (or how closely you need to listen on the other side), what kinds of interruptions are expected, and so on are there to be tweaked depending on circumstances.
I just now realized that in principle we could be in agreement, but differ in how far we're willing to tweak these parameters just to talk comfortably. I'm obviously inclined to accept even relatively rigid rules of conversation (the worse the connection, the more of a protocol I would be ok with), but I realize it may be just my personal preference. Well, food for thought me anyway, so thanks :)
This does not describe any landline I've ever used ever, either locally or long distance, even to this day, even at 00:00:01 on any given New Year's Day.
You mean yelling into the phone really loud and than also knowing your paying $0.29 a minute? The technology was bad and the quality was bad unless you were calling locally. I think what your missing is people not talking to you and not being distracted by the internet or some other diversion?
