The file isnt empty:
-rw-r--r--  1 root root 487200 Dec 31 09:18 test.alaw

I think you got me wrong, VLC CANT play the file.
If i try to open it, it is 0 seconds long.

Regards
Markus

First, I assume that your file is non-empty - i.e., you actually received data :-)

Assuming that your file is non-empty, then it *should* be containing PCM a-law audio, because that's what the server (Asterisk) reported.  The fact that VLC (which uses the LIVE555 RTSP/RTP client library) was able to decode and play the stream confirms this.  So the problem must be with the way that you are (trying to) decode it.  I'm not an expert on "ffmpeg", unfortunately (but perhaps someone else on this mailing list might be able to help you).
