Playing Audio Files over Calls on EC200U Using QuecPython

I am using the EC200U module with QuecPython, and I need to play an audio file over call. However, it seems QuecPython does not support selecting the audio channel for playing audio files over call.

Can I use AT commands within the QuecPython environment to resolve this issue?

If it’s possible to use AT commands or if this functionality is natively available in QuecPython, please provide guidance.
