To remove the assistant from your Vapi-purchased phone and trigger your server URL for inbound calls, use the following API request:

bash
curl --location --request PATCH 'https://api.vapi.ai/phone-number/your_phone_id' \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer your-vapi-private-api-key' \
  --data '{
    "assistantId": null,
    "serverUrl": "https://your_server_url"
  }'

This will ensure no assistant handles inbound calls, and Vapi will send call events to your server URL, where you can specify the agent as needed in your backend logic.
