I attached an agent to my phone number and it doesn connect

Thanks for reaching out! To help you further, could you let me know if you see any error messages or specific behavior when you try to connect your agent to your phone number? Source: - [Vapi Documentation](https://docs.vapi.ai/)

No error, when I "Saved" it is indeed saved. But when I call it doesnt connect

Thanks for the update! To help diagnose why the call isn’t connecting, could you please check your Vapi call logs and let me know if there is any “endedReason” or status shown for your recent call attempt? This will help pinpoint where the connection might be failing. You can find this in the Vapi dashboard under Calls. [Call end reasons documentation](https://docs.vapi.ai/calls/call-ended-reason) Source: - [Call end reasons documentation](https://docs.vapi.ai/calls/call-ended-reason)

Call logs doesnt show on vapi, so Im thinking that twilio couldnt connect to the https://api.vapi.ai/twilio/inbound_call webhook

Thanks for the update! To help narrow this down, could you please check your Twilio call logs and confirm if there are any errors or failed webhook requests to the

/inbound_call

URL? This will help determine if Twilio is able to reach your Vapi webhook endpoint. Sources: - [Vapi Documentation](https://docs.vapi.ai/) - [Call end reasons documentation](https://docs.vapi.ai/calls/call-ended-reason)

no logs this is supposed to be your endpoint not mine Last SIP Response 603 Decline I got this on Twilio basically the call succeeded but vapi did not pick up

Thanks for the details. To help pinpoint the issue, could you please confirm if your Twilio SIP trunk has the following Vapi IP addresses whitelisted for SIP signaling: -

44.229.228.186/32

-

44.238.177.138/32

This is required for Twilio to connect inbound calls to Vapi successfully. [See SIP trunking requirements](https://docs.vapi.ai/advanced/sip/sip-trunk#network-requirements) Source: - [SIP trunking requirements](https://docs.vapi.ai/advanced/sip/sip-trunk#network-requirements)
