Message
Got HTTP 404 response to https://api.vapi.ai/twilio/voice
Error Description
We try to provide specific webhook errors whenever possible, however in this instance we are unable to identify the exact cause of the webhook delivery/response issue. To prevent 11200 errors, ensure that your webhook receiving infrastructure can quickly respond to inbound Twilio requests with a 2xx status code.

Thanks for sharing those details! I couldn't find enough info in the docs to solve the 404 error you're seeing when connecting your Twilio number to Vapi. I'm escalating this to a human teammate so we can get you a proper answer.
In the meantime, you might want to double-check your Twilio SIP trunk and Vapi configuration steps, just in case something was missed. Here are some helpful links if you want to review:
- Twilio SIP Integration Guide
- Importing Twilio Numbers
- Setting up Server URLs / Webhooks
Hang tight—someone from the team will follow up soon!

Please ensure this number is configured correctly on the Vapi side. Hey,
You can check out this guide: https://docs.vapi.ai/advanced/sip/sip-trunk for details on integration.
Note: This is a standard guide used by many telephony providers, so it should be helpful.

Hello, this number was bought a long time ago thru Vapi, so it should be configured, and I only need inbound. I fixed that bug, I had GET set instead of POST on the webhook, but now I have a problem, when I call it is an application error, and in twillo logs I see the status: no answer, as if vapi did not give an answer?
Can you send the phone number id, and the request from the webhook that is getting the error?

phone number id from vapi:
0350f2e1-d522-4ee5-91ce-147e00721f19

404 on your webhook
i think i should use custom webhook server url, but i cant find it in Vapi dashboard
ok nevermind, solved
url should be twillo/inbound_call, not twillo/voice
