Hi, I can help you troubleshoot that. If your own number worked but your friend’s didn’t, it’s likely related to the outbound caller ID setup, number permissions, geo restrictions, or carrier filtering on the Twilio/Vapi side. The fact that it appears in the logs means the request is being triggered, but the call may not actually be completing. I’d recommend checking the phone number capabilities, verified destinations (if on trial), and the call status/error logs in Twilio.
