I have selected m4a/aac as recording format, but all my call recordings are saved with mp3 extension.

Format : MPEG-4 ... Commercial name : HE-AAC

It looks like the actual file format is AAC, but the file extension is wrong. Can you enable debug mode by long pressing BCR's version number, make a call, and then upload the log file that gets created in the output directory?

I suspect this is a bug in the Android ROM you're using though. Android is responsible for determining the file extension, not BCR.

Thanks for the logs. This might actually be a BCR bug. I'm looking into it now.

This is fixed in #368, which will be included in version 1.47.

For your existing recordings, you can just manually rename them from .mp3 back to .m4a since the file contents is already a valid M4A/AAC file.
