Thanks — I’m responding to your question about detecting voicemail beeps via tool calls. Short answer: There isn’t a built‑in tool call that specifically detects voicemail beeps. What you can do instead: • Use silence-based detection (monitor background silence interval after answer) to flag likely voicemail. • Run an LLM-based answering‑machine classifier on the call audio for ~70–80% accuracy in detecting voicemail vs live answer. • Combine both: use silence detection as a fast heuristic, then confirm with the LLM classifier and trigger tool calls (e.g.,

route_to_agent

,

leave_message

,

hangup

) based on the result. Quick question to tailor guidance: is this for outbound dialing (predicting answering machine on connect) or for inbound calls? Also, do you have real‑time audio access for immediate analysis or only recordings?
