Audio recording feature not supported by EG25-G

I am not able to record the audio of uplink or downlink with Quectel EG25-G. If I try to record the audio it is been stored into UFS but not sd card. I tried a similar feature with MC60 it worked perfectly.

Dear Sir,
this feature is being developed on EG25-G and is theoretically supported, but there is no documentation for it now.

If I consider EG25-G is new module then the same feature didn’t work on EC25 as well.
