Hey everyone,I’m currently building an AI Calling Agent using n8n and Vapi to call leads automatically. I'm using a free Vapi US number, and I'm trying to make outbound calls within the US only. However, every time I trigger a call via the HTTP request, I get this issue: - Initial status: queued - After a few seconds, the call fails with:Status: endedReason: call.in-progress.error-sip-outbound-call-failed-to-connect I've already: - Linked the free number to my assistant - Added a working script to the agent - Made sure the phone number I'm calling is valid (US-based mobile) - Set up everything correctly in n8n and the request payload Still, all outbound calls are failing with this SIP error. 👉 Has anyone faced this issue before?👉 Do free Vapi numbers support outbound calls reliably?👉 Would using a Twilio number via SIP resolve this? Any help or insights would be appreciated 🙏Thanks in advance!
