BYOC Inbound Issues

Hey Guys,

We're trying to use our own Carrier we've added the SIP Trunk and outbounds seem to be working fine but on inbounds the calls are failing. Not sure what we need to do to fix it. Inbound Caller ID: 824bceff-17ac-4276-a221-149fda0ed5c3

Thanks for reaching out! To help diagnose the inbound call issue, could you please confirm if your carrier is forwarding inbound calls to the correct SIP URI (e.g., your-number@<credential_id>.sip.vapi.aiyour-number@<credential_id>.sip.vapi.ai) as required by Vapi's documentation? This is a common cause of inbound failures.

it's forwarding to IP not SIP URI

Please ensure that your SIP trunk is using two gateways, one for inbound and one for outbound. They cannot be together in the same gateway.
