Hello, I have recently built an AI Receptionist with VAPI and n8n, and everything was working fine until I tried to make it be able to redirect calls to a human number when asked for it, but I’ve tried everything and it doesn’t work. I would appreciate some help. Thanks.

Thanks for reaching out! To help troubleshoot, could you let me know if you see any error messages or logs in Vapi or n8n when the call forwarding fails? This will help pinpoint where the issue might be.

Well, in the call transcript when I ask the agent to redirect the call to a human it says “transferring the call now” and it hangs up. The TransferCall tool shows up as completed successfully but after that there is a message saying that the call has ended due to transfer failiure

Hi Ryan, I'd be happy to help you troubleshoot the call redirect issue. To investigate, could you please provide: 1. Call ID where the redirect failed 2. How you configured the transfer (TransferCall tool vs. transferDestinations) 3. What happens when you try to redirect (does it hang up, error out, etc.?) 4. The destination number format you're using (e.g., +1XXXXXXXXXX) In the meantime, here are some resources that might help: • Configuration guide for assistant-based warm transfers: https://docs.vapi.ai/assistants/call-transfer • TransferCallTool documentation: https://docs.vapi.ai/tools/transfer-call Common issues include: • Phone number format (must include country code) • TransferCall tool not properly configured • Destination number not whitelisted Once you share the Call ID, I can check the logs to see exactly what's happening. Best, Vapi Support
