cant call inbound to VAPI using my BYO sim trunk number

Thanks for reaching out about your SIP Trunking setup! You can find step-by-step troubleshooting help here: 👉 [Vapi SIP Trunking Guide](https://docs.vapi.ai/advanced/sip/sip-trunk) If that doesn’t resolve it, please reply with: - Your Call ID - The exact error message or behavior (e.g. 401 Unauthorized, timeout, etc.) - Whether it’s happening on inbound, outbound, or both trunks - Any recent configuration changes Once we have that info, we can help pinpoint the issue faster.

Thanks for reaching out! To help troubleshoot, could you confirm if your SIP provider is forwarding inbound calls to the correct SIP URI (e.g.,

your-number@<credential_id>.sip.vapi.ai

) and if you have whitelisted the required Vapi IP addresses (44.229.228.186/32 and 44.238.177.138/32) as described in the documentation? If you have, please let me know what error or behavior you see when trying to call in. Example SIP URI:

your-number@<credential_id>.sip.vapi.ai

Required IPs to whitelist: - 44.229.228.186/32 - 44.238.177.138/32 Let me know which step you’re on or if you see any specific error! Source: - [Vapi SIP Trunk Documentation](https://docs.vapi.ai/advanced/sip/sip-trunk)
