Try updating your TransferCall tool's parameters to include the required "destination" property in E.164 format. Use the following JSON snippet in your tool configuration:

json
"parameters": {
  "type": "object",
  "properties": {
    "destination": {
      "type": "string",
      "enum": ["+1234567890"], // Replace with your external number
      "description": "The destination to transfer the call to."
    }
  },
  "required": ["destination"]
}

Update this in your function's parameters section and test the transfer again. [Reference: Vapi documentation: call forwarding](https://docs.vapi.ai/call-forwarding) Source: - [Vapi documentation: call forwarding](https://docs.vapi.ai/call-forwarding)
