When the relay's server key changes (e.g. after restart), show a styled in-app warning dialog instead of the ugly browser confirm(). The dialog shows old vs new fingerprints and lets the user accept the new key or cancel. Accepting updates the saved fingerprint and refreshes the relay button state.

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
