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?
