Why not use sox for this purpose?
sox mygsm.gsm -r 8000 -c 1 mywave.wav resample -ql
Once it's a wav you can mp3 it with lame or your preferred encoder,
but encoding and playing mp3s takes more cpu than just playing it in
gsm, or stopping after sox and playing as a wav.

My previous experience is to just use sox. It works, it's free, it
does what it says it does. What makes ffmpeg so special?
