apparently I didn’t ask the correct question with my last post: I’m looking for a foss messenger I can also send audio and video with and have a conversation over the smartphone not needing to use voip (and not needing a phone number).

I think you’re confusing things. VoIP means voice over IP. So anytime you can talk to somebody over the internet, you’re using a form of VoIP.
To have an app that doesn’t use voip but lets you talk over the internet is a contradiction and just confuses your question.
I think you’re real question is: what voice and messaging apps don’t require a phone number registration
