Three real bugs, one smoke-test session's worth of progress. 1. RELAY: wrong advertised addr in CallSetup The direct-call CallSetup computed `relay_addr = addr.ip()` where `addr = connection.remote_address()` — i.e. the CLIENT'S IP, not the relay's. So the relay was telling both parties "the call room is at the answerer's IP:4433", which meant each client dialed either the other client (no server listening) or themselves. Both endpoint.connect calls hung forever and the call never happened. Fix: compute the relay's own advertised IP once at startup. If the listen addr is 0.0.0.0, probe the primary outbound interface via the classic UDP-bind-and-connect(8.8.8.8:80) trick to discover the LAN IP the OS would use to reach external hosts. Thread the resulting advertised_addr_str into the CallSetup sender for both parties. 2. RELAY: accept loop serialized QUIC handshakes Previously the main accept loop called `wzp_transport::accept` which did both `endpoint.accept().await` AND `incoming.await` (the server- side QUIC handshake). A single slow handshake therefore blocked every subsequent client from being accepted. Unroll the helper here and move `incoming.await` into the per-connection spawned task, so every handshake runs in parallel. Also log "accept queue: new Incoming", "QUIC handshake complete", and "QUIC handshake failed" so we can tell immediately whether a client's packets are reaching the relay at all. 3. ANDROID: playout was routed to the silent in-call stream The Oboe playout stream was configured with Usage::VoiceCommunication, which routes to the Android in-call earpiece stream. That stream is silent unless the Activity has called AudioManager.setMode( IN_COMMUNICATION) and, even then, only the earpiece/BT headset get audio (not the loud speaker). Result: android→mac calls worked because mac had a normal media output, but mac→android calls were silent even though packets flowed through the relay just fine. Switch to Usage::Media + ContentType::Speech so Oboe routes to the loud speaker and uses the media volume slider. A later polish step will wire setMode + setSpeakerphoneOn from MainActivity.kt so we can go back to VoiceCommunication for AEC and proximity-sensor routing. Plus: heartbeat tracing every 2s in the send/recv tasks — frames_sent, last_rms, last_pkt_bytes, short_reads on the send side; decoded_frames, last_decode_n, last_written, decode_errs on the recv side. Will make the next "no sound" regression trivial to localize.
