I dint know if it's just me ...but the tools don't get called on their own ... The assistant knows what tool to call next ...but it doesn't... Until the users says something ...it could "ok" or "are you there" etc...only then does it make the tool call. The tool calls are synchronous, i am returning the toolcallid, the response format is per vapi docs, GPT4o , deepgram Nova 2 eleven labs,
