Hi. We have this requirement that seems to fit A9G module hardware perfectly.
We need to build a solution that call certain phone number and play an audio file from SD card to them during the period of the call.
Currently we can call and play audio file but not both at the same time. While playing an audio, if a call is made, the playback is paused until call ended and if we try to play during a call, it return an error indicating a call is in progress.
I believe this limitations are imposed by the firmware of the A9G module, which unfortunately is not open-source.

Is there a way around this?
