Hi there! 👋 I understand you're dealing with a frustrating "phantom assistant" issue that's still attached to your phone number even after deletion. While I don't have specific information about your particular phone number, I can definitely help with general steps to disconnect persistent phantom assistants. Here's how you can disconnect that phantom assistant: ## Standard Disconnection Procedure First, try the standard deletion process again: 1. Delete the assistant using the API endpoint

https://api.vapi.ai/assistant/:id

with your assistant's ID [API Reference](https://docs.vapi.ai/api-reference/assistants/delete) 2. Release the phone number through Twilio's API if it was obtained through Twilio [Discord Thread](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1335389709035110430) ## Set Assistant ID to Null You can try explicitly disconnecting the assistant by setting the assistant ID to null:

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"
    }'
