Hi @Shubham Bajaj, I am also struggling to configure the tool to transfer to one of several options and wondering if you could clarify this a bit. I've created a tool that looks nearly identical to [this call forwarding example that is sent around in the channel](https://docs.vapi.ai/call-forwarding) except with numbers that I own. I've attached that transferCall tool to my assistant also prompted the LLM like this: If you are asked to transfer to department A, call the transferCall function with a destination of ... In the call logs, the function is getting called with the appropriate destination number and the logs indicate it is a success. However, the call just ends (doesn't transfer). When I call the destination number the assistant tried to transfer, it is functional (it is currently a Vapi-manageed number that is assigned to a Vapi assistant). How does the ServerMessageTransferDestinationRequest tie into this workflow? Is this mandatory to set up the transferCall tool?
