in agent 0.x, how would i make sure the inbound SIP participant has joined the room prior to starting or creating the agent?

Thanks for reaching out, Kush. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

I have a dispatch rule for inbound calling. I want make sure the SIP participant has joined the call prior to the agent starting. From my understanding, the SIP participant could have joined the room before the agent job/process was even created. So how would I capture if the SIP participant has joined from the agent's perspective?

Hey there! Let me break down how you can track SIP participants joining a room in LiveKit agent 0.x in a super friendly way. • You'll get a notification when someone new joins the room. • The system will peek at the participant's identity to see if they're coming in via SIP. • If it's a SIP participant, it'll grab the specific task associated with them. • Then it sets up everything needed to welcome and interact with that participant. Here's the code that makes the magic happen:

@ctx.room.on("participant_connected")
def on_participant_connected(participant: rtc.RemoteParticipant):
    <http://logger.info|logger.info>(f"new participant joined {participant.identity}")
    if not "sip_" in participant.identity:
        return

    # Get the task from attributes
    task = participant._info.attributes.get("task")
    <http://logger.info|logger.info>(f"task: {task}")

    # Initialize user data
    userdata = UserData(task=task)

    # Create and start the agent session
    session = AgentSession(
        userdata=userdata,
        stt=deepgram.STT(),
        llm=openai.LLM(base_url="<https://api.deepseek.com/v1>",
                      model="deepseek-chat",
                      api_key=os.getenv("DEEPSEEK_API_KEY")),
        tts=cartesia.TTS(),
        vad=silero.VAD.load(),
        min_endpointing_delay=0.75
    )

    # Start the navigator agent
    asyncio.create_task(
        session.start(
            room=ctx.room,
            agent=NavigatorAgent()
        )
    )

This approach helps you smoothly welcome and handle SIP participants in your room. Pretty cool, right? 😊 Sources: Building an Automated IVR Menu Caller | LiveKit Docs

what if the SIP participants has already joined the room prior to the creation of the agent? then would this still capture it?

Hey there! I totally understand you might need some clarity about querying room participants. I'm here to help! Could you tell me a bit more about the specific SDK or API you're using to manage your room? The more details you can share, the better I can tailor a solution that works perfectly for your situation. I'm all ears and ready to dig into this with you! 😊

In simple terms, I want to check to see if a SIP participant exist in my room in the agent 0.x. How would I do that?

I don't have the answer you're looking for. You could also try asking your question: • in one of the other Slack channels or • to https://deepwiki.com/livekit/livekit_composite which is trained on all LiveKit source code If you find the answer, please post it here to help others!
