This is the best summary I could come up with:
Calls on WhatsApp are (optionally) getting even more secure for the app’s most privacy-minded users.
When activated, calls will be relayed through Meta / WhatsApp servers, thus concealing your true IP address.
This direct connection allows for faster data transfers and better call quality, but it also means that participants need to know each other’s IP addresses,” WhatsApp’s Daniel Sommermann, Sebastian Messmer, and Attaullah Baig wrote in the post.
“IP addresses may contain information that some of our most privacy-conscious users are mindful of, such as broad geographical location or internet provider.”
The other measure mentioned in the blog post is an option to silence unknown callers (first announced in June), which WhatsApp says prevents spam disturbances and also shuts down a vector for complex cybersecurity attacks.
“Protecting user privacy and security is absolutely necessary for WhatsApp to accomplish its mission to enable private communication for the world,” the blog post reads.
