### Answer Based on the available sources, I don't have specific documentation on how to live monitor a Retell voice agent call in real-time (such as listening in on an active call) . However, the sources do mention some related monitoring capabilities: Webhook-based call monitoring allows you to receive real-time notifications when calls start and end via the

call_started

and

call_ended

webhook events. [(1) ]() Dashboard visibility - Depending on compliance regulations, you can monitor live calls in progress and view detailed analytics on agent performance from your dashboard. [(2) ]() Real-time transcription - Retell provides live transcription that works during conversations via Automatic Speech Recognition (ASR) . [(3) ]() For detailed instructions on live call monitoring (such as listening to calls in progress or real-time call supervision) , I'd recommend checking these potentially useful sources: - [Webhook Overview]() - [Retell AI | AI Voice Agents for Enterprise Calls]() Would you like me to provide a general answer based on my knowledge, or would you prefer to reach out to Retell support via [Contact Sales]() for specific live monitoring capabilities?
