Bug Report Call Transfer Tool Not Triggering
# support

Call ID: d45d73c7-b96f-4e8e-a857-7134a0231e72 Issue: The assistant identifies the correct department and speaks the transfer announcement correctly, but the transfer tool never fires. The call loops — the assistant repeats the announcement, VAPI fires the idle message "Are you still there?", the caller responds, and the loop starts again. The caller eventually hangs up. Tool name: auto_transfer_call_tool Transfer mode: Blind Transfer Destinations: 5 configured (Lettings, Sales, Property Management, Tenancy Progression, Accounts) What the assistant says correctly: "I'm putting you through to Property Management now." What happens after: Tool never fires. Call sits in silence. Idle message triggers. Loop repeats 3–4 times before caller disconnects. What we have checked: - Tool name matches exactly in both the prompt and VAPI - All 5 destinations are configured with phone numbers and descriptions - Transfer mode is set to Blind Transfer on all destinations - "Wait for message to be spoken" setting checked - Prompt instructs the model to call the tool immediately after the announcement Expected behaviour: Announcement spoken → tool fires immediately → call transferred to correct destination. Actual behaviour: Announcement spoken → nothing → idle message fires → loop. Any help appreciated. Is this a known issue with the auto transfer tool?
