Hi guys, just spoted a BIG BUG with call transfers in your UI. Multiple destinations dont work at all and first destination is selected. Because the properties of argument object of the tool are empty even when destinations are created. So, no phone number gets passed into the function. When I updated the tool by cURL to add the property, it started to transfer properly. So this is definitely a BIG BUG. Can you fix this? -d '{ "function": { "name": "transfer_call_tool", "description": "Use this function to transfer the call. Only use it when following instructions that explicitly ask you to use the transfer_call_tool. DO NOT call this function unless you are instructed to do so. If it is new client use +YYYYYYYY else (for existing customers) use +XXXXXXXXX", "parameters": { "type": "object", "properties": { "destination": { "type": "string", "enum": ["+YYYYYYYYYY", "+XXXXXXXXXXX"], "description": "The destination to transfer the call to." } }, "required": ["destination"] } } While your UI has created this UGLINESS { "function": { "name": "transfer_call", "description": "Transfers the caller to a human representative or lawyer, handing off the conversation with full context.", "parameters": { "type": "object", "properties": {}, "required": [] } }, } This child of incest exists already for 4-5 months ... as I read reports on forums. Whats going on?

To fix the call transfer bug, update your tool's parameters to explicitly include the

destination

property. Here’s a working example you can use with cURL:

json
"parameters": {
  "type": "object",
  "properties": {
    "destination": {
      "type": "string",
      "enum": ["+YYYYYYYYYY", "+XXXXXXXXXXX"],
      "description": "The destination to transfer the call to."
    }
  },
  "required": ["destination"]
}

Apply this structure to your tool definition, and the transfer should work as expected. [Reference](https://docs.vapi.ai/call-forwarding) Source: - [Vapi documentation: call forwarding](https://docs.vapi.ai/call-forwarding)

https://docs.vapi.ai/api-reference/assistants/create have you tried to read their docs here? it's laid out very well on how to set up the transfer assistant.model.openai.tools.TransferCallTool @козак

I see, but why it doesn work in UI?
