<p class="MsoNormal">You appear to be receiving the audio correctly, so I suspect your problem is simply that you are not decoding it properly.<o:p></o:p></p>

<p class="MsoNormal">The data in your file ("test.alaw") should be PCM a-law audio, 1 channel, with a sampling frequency of 8000 Hz. You probably need to tell "ffmpeg" explicitly what kind of data this is; it probably won't be able to 'guess' the data type
otherwise.<o:p></o:p></p>
