Are your calls encrypted?
FaceTime seals calls by default, and Zoom does only if the host turns it on. Normal phone calls, Google Meet group calls and Microsoft Teams calls on personal accounts aren't sealed end to end.
Sorted by how many parts are sealed by default, then by how many can be. Ties go A to Z.
