A caller calls in to the main number of a company and asks to be transfered to "John Smith on ext.xxx". How can we implement that?

<@1306708454735347772>
To transfer a call to "John Smith on ext.xxx," we would need to use the `transferCall` function. However, I would need the specific extension number to complete the transfer. Could you please provide me with the full extension number for John Smith?

You can continue this conversation by mentioning me in the message.

Extension number is dynamic depending on caller request

```json
  "destinations": [
    {
      "type": "number",
      "number": "91xxx91xxx",
      "extension": "457",
      "callerId": "ShubhamBajaj",
      "description": "Destination number",
      "message": "transfer with extension check",
      "numberE164CheckEnabled": false
    }
  ]
```

<@1306708454735347772> pass the phone-number-extension into `extension` property.
