Can you confirm if my organization (Org ID: a82276bd-7a64-4611-9c2f-d142ab934f95) has Twilio or any outbound SIP/PSTN provider connected for use with transfer_call_tool?
We are triggering the tool and getting "tool_call_result": "No result returned", which suggests the transfer is not completing.
We have a valid phone number destination and a properly structured webhook response.

05/12/2025, 9:42 PMHey VAPI team —
We’re trying to run a live warm transfer using transfer_call_tool to connect our assistant Rachel to+1 (786) 280-4399.
The toolCall is triggering properly, but we keep getting: "tool_call_result": "No result returned".
We purchased our number through VAPI (+1 (786) 460-9275), and have it assigned in our assistant.
Can you confirm whether our org (a82276bd-7a64-4611-9c2f-d142ab934f95) is:
✅ Enabled for outbound warm transfers via PSTN?
✅ Linked to the correct SIP trunk or Twilio route?
✅ Approved to dial the number: +17862804399?
Here’s our transfer_call_tool ID: 5879d89b-ce6d-40dc-b57c-91c488713232.
