Hi there! 👋 I understand you're experiencing issues with call transfers going to incorrect numbers, which is definitely frustrating especially when it's affecting client bookings. I'm unable to analyze the specific call IDs you've shared or verify the exact content of your prompts. However, I can help troubleshoot the general issue of incorrect call transfers in Vapi based on information I've found. Here are some potential causes and troubleshooting steps for your call transfer issues: ## Initial Checks and Configuration Verification * Verify the forwarding number: Ensure that the forwarding number is correctly entered and in the proper E.164 format (e.g., +15558675309).

Hey Liv, I checked your calls, and your assistant is transferring to the destination, which is part of your assistant's forwarding phone number. That's why your calls are going there. Regarding you, your prompt doesn't have any search instructions. It's coming from your prompt alone. I suggest you rework your prompt and look for transfer call functions. You should remove unexpected transfer calls that originate from your assistant by your prompting/evaluation.
