To disconnect a SIP call when silence is detected, you can implement a silence detection mechanism using a timer that monitors user interaction and disconnects the call after a specified period of silence. Below is a step-by-step guide: 1. Set Up Silence Detection: Implement a timer to track the duration of silence during the call. For example:

SILENCE_THRESHOLD = 5  # seconds

async def monitor_interaction():
    while True:
        if time.time() - user_last_spoke_time > SILENCE_THRESHOLD:
            <http://logger.info|logger.info>("Silence exceeded threshold. Disconnecting call.")
            try:
                await ctx.room.disconnect()
            except Exception as e:
                logger.exception("Error disconnecting call")
        await asyncio.sleep(1)

2. Track User Speech: Update the silence timer whenever the user starts speaking:

@agent.on("user_started_speaking")
def on_user_started_speaking(_msg):
    global user_last_spoke_time
    user_last_spoke_time = time.time()

3. Start Monitoring: Run the silence detection coroutine alongside your main execution:

monitor_task = asyncio.create_task(monitor_interaction())

4. Clean Up: Ensure the monitoring task is properly cleaned up when the session shuts down:

async def on_shutdown():
    <http://logger.info|logger.info>("Shutting down session")
    if monitor_task:
        monitor_task.cancel()

ctx.add_shutdown_callback(on_shutdown)

Adjust the silence threshold and implement proper error handling as needed. Let me know if you need further assistance with this implementation! Sources: SIP Integration | livekit/livekit_composite | DeepWiki
