I need to pass a specific callerid so AE knows its a transfer from ai, but it doesnt work. https://cdn.discordapp.com/attachments/1417634366871306371/1417634367223889950/image.png?ex=68cb3263&is=68c9e0e3&hm=be7a62eef886ed60f4cff8992af740b681db704e15fd2b7f542ac64c7c8ec770&

To pass a specific caller ID when transferring a call, ensure your

transferCall

tool's destination includes the

callerId

field, like this:

json
{
  "type": "transferCall",
  "destinations": [
    {
      "type": "number",
      "number": "+19148889260",
      "callerId": "+16193298383"
    }
  ]
}

Make sure your SIP provider supports custom caller ID and that SIP REFER is enabled for transfers. For more details, see the [Vapi call forwarding documentation](https://docs.vapi.ai/call-forwarding). Source: - [Vapi Call Forwarding Documentation](https://docs.vapi.ai/call-forwarding)

Could you please test the transfer without the callerId?
