Yes,

but my problem is that I did exactly that, I was switching the codec to
Speex in OpenMeetings and tested the recording, the problem was that FFMPEG
was not able to strip the audio correctly from the stream.

However I think there are also some changes in your code required to
transcode Speex2GSM and GSM2Speex.

The 8KHz sample rate is a strict requirement? I think 8KHz is rather bad
quality, is it possible to use higher sampling rate? Maybe 16 or 32 KHz?
