WhatsApp Blocking Encrypted Calls to All Saudi Numbers

WhatsApp claims that "the Saudis are blocking the initial handshake [for encrypted calls]" and that this is why encrypted calls are dropped. However, I insist that WhatsApp is dropping all encrypted calls made by, or received by any WhatsApp user that registers with a Saudi number, regardless of whether they are connecting from Saudi Arabia, the United States via WiFi, or Tahiti.
