问题
Is it possible to modify an active call by overlaying a sound track during the call? I looked up the SDK, but couldn't find any API to do this in the documentation.
I am trying to investigate the feasibility of playing a previously recorded call/audio clip onto an ongoing call.

No, sorry, there is no API to access the in-call audio stream.
