Re:WhatsApp Blocking Encrypted Calls to All Saudi Numbers

This would work for a call in-progress. The gist explicitly claims the calls are blocked during the handshake, which would be before there's enough data to analyze. It appears from other comments that what's really going on is calls simply use a different port and that port is blocked.

The root comment on this thread resolves that distinction: it might make sense from a UX perspective to block calls that are known in advance not to be workable. WhatsApp can sensibly be reacting to something that occurs once a session is in steady state.

Sure, though I think there's still merit in the OP's request for WhatsApp to detect when a customer with a Saudi number is actually in another country and allow the call to go through (though I don't know how easy it is to detect that).
