Hi there! 👋 I wasn't able to find specific code examples for implementing the 10-second delay with a prompt for inactive users, but I can definitely help with whether this is possible and the general approach! Yes, you can implement this functionality with a Custom LLM using Python, FastAPI, and webhooks. Here's how you can approach it: ## General Architecture According to [Vapi documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1330803502615625738), you can configure your Custom LLM to receive call events via webhooks, process these events, and trigger appropriate responses. This is perfect for your use case where you need to track inactivity. ## Setting Up Your Webhook Endpoint You can create a FastAPI endpoint to handle incoming call data. Here's a simplified example of how you might set up a webhook endpoint:

python
@app.post("/twilio/inbound_call", response_class=PlainTextResponse)
async def receive_call_data(
        AccountSid: str = Form(...),
        # Other parameters...
):
    # Process the call data
    # ...
    # Forward to Vapi
    # ...

## Implementing the Delay Logic For the 10-second delay and inactivity check, you would need to implement a timer or delay function in your Custom LLM's backend logic. According to [this source](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1333783762579755020), the general approach would be: 1. Play the initial message to the user 2. Start a timer (10 seconds in your case) 3. Listen for a response 4. If no response is detected within the specified time, send the follow-up message ## Configuring Idle Messages While you mentioned you don't want to use idle messages specifically, the configuration approach is similar. In Vapi, you can configure message plans with parameters like: ```python class MessagePlan(BaseModel): idleMessages: List[str] = ["Are you still there?"] idleMessageMaxSpokenCount: float = 3

So if initial message is spoken, customllm doesn't get any response, idle message is spoken

But can we do custom Idle messages? UI dont seem to have such feature, just choice list.

The intented use case is to add user message to the converation - https://docs.vapi.ai/calls/call-features

One more quick question @Kings_big💫 https://docs.vapi.ai/calls/call-features 2. Add Message to Conversation

py
curl -X POST 'https://aws-us-west-2-production1-phone-call-websocket.vapi.ai/7420f27a-30fd-4f49-a995-5549ae7cc00d/control' 
-H 'content-type: application/json' 
--data-raw '{
  "type": "add-message",
  "message": {
    "role": "system",
    "content": "New message added to conversation"
  },
  "triggerResponseEnabled": true
}'

Can do the same to add message for

user

to simulate?
