End-to-end encrypted calls between two contacts over WebRTC. Call signalling (offer, answer, hang-up) travels as ordinary Signal-encrypted messages through the relay; media is DTLS-SRTP, peer to peer when possible and through the operator's TURN server otherwise. - Non-trickle ICE (candidates gathered for up to 3 s), 45 s ring timeout, busy handling, and a call log entry in the conversation. - The system call UI rings even when the app is closed: CallKit from a PushKit VoIP push on iOS, a full-screen incoming call from an FCM wake-up on Android. The wake-up carries no caller; the app learns who is calling from the queued offer once it is unlocked. - New permissions: camera for video, audio routing and Bluetooth headsets, network state; iOS background modes audio and voip. Push on Android: a fresh install now picks UnifiedPush when a distributor is installed and FCM otherwise, instead of leaving wake-ups off. Without a wake-up Android puts the app to sleep and messages wait until it is opened. Users can switch at any time in Settings.
