I'm using Google Duo a lot and (to my surprise) it claims to be end-to-end encrypted: https://support.google.com/duo/answer/9280240?hl=en https://support.google.com/duo/answer/9280240?hl=en I started to use it as an alternative to WhatsApp calls for their superior call quality. Many people already have it without knowing about it. AFAIK that's due to being preinstalled on newer devices or being available as an instant app(?) That does seem to imply that you don't have to actively install it to work? ... but I'm not sure.
