### Answer
I don't have information in the available sources about a built-in feature to detect if another AI bot is on the other end of a call with your Retell agent.
The documentation covers features like voicemail detection, but detecting AI-to-AI conversations isn't mentioned.

Check out these potentially useful sources:
- [AI Voice Agent Platform for Phone Call Automation - Retell AI](

- [AI Voice Agent](

- [Documentation](

Would you like me to try a general answer based on my knowledge, or you could reach out to Retell support directly via [Contact Sales](
) for clarification on whether this capability exists or is on the roadmap?
