### Answer I don't have explicit documentation showing how to override the

response_engine

specifically when creating a phone call using the Python SDK. The Python SDK provides methods for creating phone calls: [(1) ]()

python
client.call.create_phone_call(**params)

And for registering phone calls:

python
client.call.register_phone_call(**params)

There is an

agent_override

parameter available for

register_phone_call

, which allows overriding agent settings like

voice_id

. [(2) ]() However, I don't have documentation confirming whether

response_engine

can be overridden through this mechanism or what the exact parameter structure would be. Check out these potentially useful sources: - [Create Phone Call API]() - [Register Phone Call API]() - [Python SDK API Reference]() Would you like me to provide a general answer based on my knowledge instead?

​ To learn more, see the sources I considered: [[1] RetellAI/retell-python-sdk/api.md](https://github.com/RetellAI/retell-python-sdk/blob/main/api.md) [[2] /v2/register-phone-call ignores agent_override](https://discord.com/channels/1186424376300679209/1451520682667147376) ​
