I'm using a SIP trunk. Outbound worked, but inbound didn't. So, the system isn't picking up incoming calls. How can I fix this?

Thanks for sharing your issue. Can you confirm if your SIP provider is forwarding inbound calls to the correct SIP URI (e.g.,

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

)? This is a common cause for inbound call issues according to the documentation I have found. Source: - [Vapi SIP Trunk Documentation](https://docs.vapi.ai/advanced/sip/sip-trunk)

If your outbound calls work but inbound calls don’t, it means your SIP provider isn’t sending the incoming calls to VAPI correctly. You need to check your SIP trunk settings and make sure the inbound route is pointed to your VAPI SIP address (something like sip:@sip.vapi.ai). Also confirm that your SIP trunk is registered — if the registration drops, inbound calls will fail even though outbound still works. Once the inbound route is set to the correct VAPI SIP domain and the trunk is properly registered, your incoming calls should start working.

Please provide your phone number id or credential id and we will review the configuration
