Issue Description: I have added an inbound number attached to an assistant. It is showing as attached but the number does not appear in the Numbers tab. I deleted the assistant to re-create a new one, but now I get the error: "error": "This phone number is already linked to another account. Please use a different phone number." I have added two numbers, but none of them are showing in my account. Organization ID: 95c8ce8e-e822-4f00-a905-88150b175382 Phone Number Details: Phone Numbers: +13466622596 +17473494524 Assistant ID: ff4a8eab-27bd-4ad1-b904-87320f8a57e0 Call Type: Inbound Phone Number ID: 2bcc173b-4c40-4686-aedc-b7730b2e9c13

Suggestion: Try re-importing your phone number using the Vapi dashboard or the

/phone-numbers/import

endpoint, ensuring you use the correct credentials and account. If the number is still reported as "linked to another account," please contact Vapi support directly, as this error typically requires backend intervention to resolve account linkage issues. Example API call:

bash
curl -X POST https://api.vapi.ai/phone-numbers/import \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "number": "+13132419645" }'

The phone numbers must be in your account before you can attach them to your assistant. Are you associated with the org that currently owns these numbers or did you purchase these from Twilio?
