hello I am using n8n agent and vapi to make calls . The number I am using to test the API call is +18186541234, but in the output, I see : 400 - "{\"message\":\"Couldn't start call. Free Vapi numbers do not support international calls.\",\"error\":\"Bad Request\",\"statusCode\":400}" But it is not an international number and is a USA number When I try the number without the country code +1, it shows another error that the number should be entered with the country code So what is wrong here? How can I test my workflow with a USA number? I need your help assistant id : 6268b8ea-4286-4a77-a518-73abe10f3a48 phone id : dd010eec-497b-4728-9d54-52841e94d9ea thank you

Hey, I see you're having trouble with the API call using the number +18186541234. It seems like the system is treating it as an international number, which is causing the error. To test your workflow with a USA number, make sure you're using a valid number format with the country code included. If you're still facing issues, it might be worth checking if the number is eligible for use with the free Vapi service. Let me know if you need further assistance.
