Function Call Response
Configure the voice agent and configure the function call response.
When the LLM decides to call a function, it sends a message to the client indicating the need to invoke a specific function—this message is called a FunctionCallRequest. In response, the client processes the request, calls the desired function, and then sends back the result as a FunctionCallResponse.

to the server. You know your function call was processed successfully if the conversation proceeds and the agent replies
Conclusion
the FunctionCallResponse
message serves as a standardized JSON command that the client must send in direct response to each FunctionCallRequest received. This ensures consistent communication, facilitates prompt data exchange, and maintains a reliable workflow between the client and server.
