A caller's reply was generated but never heard: 0.65s after the agent started speaking, the VAD fired "user started speaking" (NO transcript) and broadcast an interruption that cancelled the agent's audio -> ~24s of silence until the caller spoke again. Cause: the agent's own TTS echoes back the phone line and the always-on VAD interruption treats it as a barge-in. (PipelineParams has no allow_interruptions in this pipecat build — it was a silent no-op.) Fix: HalfDuplexGate before the VAD withholds inbound audio while the bot speaks (+ECHO_TAIL_SECS, default 0.5s), so echo can't trigger a false barge-in. Half-duplex (no mid-utterance barge-in); HALF_DUPLEX=false to restore it. Runtime-tested the gate (pass idle / drop while speaking / drop in tail / resume).
