05/27/2025, 8:42 PMIs there any way to play an audio file while agents make tool calls? Either dashboard or API?
Example: "Can you please schedule a meeting?"
Agent: " Sure thing, one second."
Tool Call triggers mp3 or wav file (public URL or on vapi?)
wav file play a hold music until tool call complete.

05/28/2025, 9:29 AMI ended up using the client messages in the SDK. It worked well. I simply checked for all tool calls.
// Check for tool calls starting
const hasNewToolCall = message.messages?.some((msg: { role: string; toolCalls?: any[] }) =>
msg.role === "tool_calls" &&
(msg.toolCalls && msg.toolCalls.length > 0)
);
// Check for tool call results/completion
const hasToolResult = message.messages?.some((msg: { role: string; content?: string }) =>
msg.role === "tool_call_result" ||
(msg.role === "tool" && msg.content !== "Tool Result Still Pending But Proceed Further If Possible.")
);
