Answering a call no longer takes seconds: while it rings, the connection is made with the caller's offer and its routes (TURN's too) gather, and the caller's relays and TURN credentials are looked up — Answer only adds the microphone and camera and replies (3.2 s → 0.2 s on a simulated network). An open conversation warms the same for calling out. A remote signer's offer or answer waits for a direct and a relayed route or 1.5 s, not for all of them (up to 4 s).
