This is a debug-signed first build. It provides separate internet calls and does not modify normal SIM or WhatsApp call audio; Android does not expose a universal third-party API for that. Calls have been checked for signaling relay, but live voice quality and cross-network calling still need device-to-device testing. A TURN relay may be needed on restrictive networks.
