Teleconference is, at best, good enough and will never have the quality of in person discussion.
I am not aware of any teleconference software that uses perfectly lossless audio. Those small losses, though hard to hear, can increase the cognitive load of participants. Even with expensive headsets and good software, audio volumes will vary from speaker to speaker. Automatic volume leveling loses even more audio fidelity.
Due to physics (i.e. we cannot send a signal faster than the speed of light) and processing, there will be additional delay. It makes it hard for people to talk without speaking over each other. It makes discussions trickier since people are hesitant to talk right after one another. Instead of interrupting with questions, they will hold questions until the end, when the context may be forgotten, or don't ask questions at all.
Even assuming that everyone has good lighting and has their camera pointed perfectly, body language is often lost. Every meeting software I have used hesitates to switch the focused speaker too often. If two people are talking back and forth, one will be religtated to a thumbnail video. When someone is presenting, they cannot easily scan the room to see reactions.
So, when talking on a meeting, the participants hear (almost) everything being said, but they miss out on all of the non-verbal communication and even some subtleties of the sound.
