Most video calling software uses STUN NAT hole punching and not central relay servers. You are definitely publicly routed when you call through Google Meet or WhatsApp or FaceTime

if i read this right, whatsapp calls go thru relay servers?

To be fair, I think Google Meet with multiple participants still uses a relay server, instead of N^2 streams, but I may be wrong.
