Replaces the Android-side CallEngine::start() stub with a real implementation that mirrors the desktop start() body but routes all PCM through the standalone wzp-native cdylib loaded at startup via libloading instead of using CPAL. - desktop/src-tauri/src/wzp_native.rs: new module with a static OnceLock<libloading::Library> + cached raw fn pointers for every symbol we need (version, hello, audio_start/stop, read_capture, write_playout, is_running, capture/playout_latency_ms). init() resolves everything once at startup; accessors return default values if init() never ran. - desktop/src-tauri/src/lib.rs: drop the inline dlopen smoke test, add `mod wzp_native;` behind target_os="android", and invoke wzp_native::init() from the Tauri setup() callback so the library is loaded + all symbols cached before any CallEngine can touch audio. - desktop/src-tauri/src/engine.rs: the Android #[cfg] branch of CallEngine::start() now does the full QUIC handshake + signal loop + Opus send/recv tasks, calling wzp_native::audio_start() / audio_read_capture() / audio_write_playout() instead of the desktop CPAL rings. SyncWrapper now holds a placeholder Box<()> on Android because the audio backend lives in a process-global singleton inside libwzp_native.so rather than being owned per-engine. Next step: build #39 on the remote docker builder and smoke-test on Pixel 6 that the Connect button in the UI successfully brings up Oboe and streams audio through the dlopen boundary.
WarzonePhone
Custom lossy VoIP protocol built in Rust. E2E encrypted, FEC-protected, adaptive quality, designed for hostile network conditions.
Quick Start
# Build
cargo build --release
# Run relay
./target/release/wzp-relay --listen 0.0.0.0:4433
# Send a test tone
./target/release/wzp-client --send-tone 5 relay-addr:4433
# Web bridge (browser calls)
./target/release/wzp-web --port 8080 --relay 127.0.0.1:4433 --tls
# Open https://localhost:8080/room-name in two browser tabs
Architecture
See docs/ARCHITECTURE.md for the full system architecture with Mermaid diagrams covering:
- System overview and data flow
- Crate dependency graph (8 crates)
- Wire formats (MediaHeader, MiniHeader, TrunkFrame, SignalMessage)
- Cryptographic handshake (X25519 + Ed25519 + ChaCha20-Poly1305)
- Identity model (BIP39 seed, featherChat compatible)
- Quality profiles (GOOD/DEGRADED/CATASTROPHIC)
- FEC protection (RaptorQ with interleaving)
- Adaptive jitter buffer (NetEq-inspired)
- Telemetry stack (Prometheus + Grafana)
- Deployment topology
Features
- 3 quality tiers: Opus 24k (28.8 kbps) / Opus 6k (9 kbps) / Codec2 1200 (2.4 kbps)
- RaptorQ FEC: Recovers from 20-100% packet loss depending on tier
- E2E encryption: ChaCha20-Poly1305 with X25519 key exchange
- Adaptive jitter buffer: EMA-based playout delay tracking
- Silence suppression: VAD + comfort noise (~50% bandwidth savings)
- ML noise removal: RNNoise (nnnoiseless pure Rust port)
- Mini-frames: 67% header compression for steady-state packets
- Trunking: Multiplex sessions into batched datagrams
- featherChat integration: Shared BIP39 identity, token auth, call signaling
- Prometheus metrics: Relay, web bridge, inter-relay probes
- Grafana dashboard: Pre-built JSON with 18 panels
