### Answer
Based on the available documentation, I don't have specific information about manually intervening in or ending live calls outside of the agent's programmed logic.
The documentation covers automated call handling through the Call Transfer Node [(1) ](
) for transferring calls to human agents, and discusses warm transfer capabilities [(2) ](
) [(3) ](
) where the AI can hand off calls to human agents with context. However, none of these sources explicitly describe a manual intervention feature for ending or taking over calls while they're in progress.
For a definitive answer on manual call intervention capabilities, I recommend:
- Checking the [Call Transfer Node documentation](
)
- Reviewing the main Retell AI documentation for call management features
- Contacting Retell AI support directly about manual intervention options
Would you like me to provide a general answer based on my knowledge instead?
