There’s ViLTE to provide exactly that. I don’t know of many (any) carriers that offer it, though. Maybe in some business use cases?
One reason not to use it: there’s basically no encryption on any of it. Your carrier, government, and anyone who can get into the network can listen and watch along, just like they can with any voice call, unlike any modern messenger and mobile video calling apps. Hell, even Telegram has decent encryption for their video calls and they can’t even encrypt their group chats.
