But I was wrong... That will only convert it to another wave file
In my case, double the size, but still wav despite the extention.
(But this is what you wanted, I believe)
Then to get it to .mp3 I needed to do it as follows.:

ffmpeg.exe  -c pcm_alaw  -i test123.sample  test.wav
ffmpeg.exe  -i test.wav  test123.mp3

So in your case the test.wav would be your answer.

It might be that I've been misleading with the former subject, Danie. The
a/m sample is g729 raw audio packets. Attempting the cmdline you've offered
yields:

test-123.sample: Invalid data found when processing input

Both on windows (ffmpeg-git-e403a97-win64-shared) and linux.
Where you actually successful in executing this cmdline?
