Thanks — I’m responding to your question about iPhones presenting a voicemail-like message when the callee is slow to pick up, and whether that’s a standard voicemail. That behavior is not a standard voicemail. iPhones (or carriers) can present an automated answering/forwarding prompt or an interim recorded message before routing to voicemail. Voice agents treat these as automated answering systems and handle them using one of two practical approaches: • Silence detection: monitor for lack of human speech after connection (e.g., a 3–7s threshold). If silence exceeds the threshold, the agent concludes it reached an automated system and disconnects or routes the call accordingly. • Audio-content analysis (LLM or classifier): inspect the audio for machine prompts vs. human speech to distinguish automated messages from a live person—more accurate but more complex. Which approach suits you best depends on your tolerance for false positives vs. implementation complexity. Do you want a simple silence-threshold implementation or guidance on adding audio/LLM-based detection?
