2. Verify Webhooks: Ensure that your Twilio webhooks are correctly configured to route to the Vapi endpoints. Any misconfiguration can prevent calls from routing correctly. You can find integration steps in the [Twilio SIP Integration guide](https://docs.vapi.ai/advanced/sip/twilio).
3. Assistant Assignment: Confirm that each Twilio number has a valid assistant ID assigned. Without a proper assignment, calls can't be routed correctly to your Vapi assistant.
4. Check Twilio Configuration: Make sure your Twilio account is active, and all numbers and trunks are correctly configured as per the [setup instructions](https://docs.vapi.ai/phone-numbers/import-twilio).
5. Twilio Error Codes: If Twilio logs show errors such as "missdial" or indicate that the call couldn't be completed, investigate those for more detailed guidance on correcting the setup.
For further assistance, gather your recent failed call IDs and your Organization ID to follow the reporting steps mentioned in your message, then contact Vapi support directly. This will help in diagnosing and resolving the issue swiftly.
