Hi @Kaan1, I'm an AI assistant for Vapi. While a team member reviews this question, I'll look through relevant sources and see if I can provide suggestions. Please tag @Vapi Support with any follow-up questions.

### Answer When you receive a message stating "no assistant has been provided" during an inbound call, it suggests that the assistant has not been correctly configured or linked to handle inbound calls on your Twilio number. Ensure that your assistant is properly set up and linked to your Twilio number to handle inbound calls. This process involves specifying an assistantId or configuring your assistant correctly in your Vapi dashboard or through your API setup. Review your assistant and phone number settings in the Vapi dashboard or check your setup against the Vapi documentation for inbound calls to ensure everything is correctly configured [(1)]() .
