I think my assumption that mod_amrwb in passthrough mode allows native playback was wrong.

But at lest I made some progress. Master branch includes integration with libvo-amrwbenc and libopencore-amrwb libraries. With them I can transcode WAV to AMR-WB on the fly.

But playback of native AMR-WB file with mod_native_file still fails. No errors, just silence.

The question remains: is it possible to natively play AMR files without transcoding with FS?

Hi,
I have FreeSwitch 1.6.19 with mod_amrwb and mod_native_file installed.
But when I try to playback amr-wb file I see the following error "cannot play or record native files with variable length data".

Is it possible to play amr and amr-wb files with FS and if so how?
